Recently several visitors of blog have asked me about this ebook, which is being advertised quite widely across the Internet. So I purchased a copy myself to find out what all the fuss was about.

My opinion on this e-book is, if you do not have this e-book in your collection, your collection is incomplete. I have no regrets for purchasing this.

Adopt the habit mindset instead of the diet mindset

The first step towards losing fat permanently has more to do with your mindset than it does with nutrition or exercise. You have to change your entire attitude about nutrition and exercise. Instead of adopting the mindset of short-term diets, you must adopt the mindset of lifelong habits. A habit is a behavior that you perform automatically without much conscious thought or effort. Once a habit is firmly established - good or bad - it takes enormous strength to break it. It's like trying to swim upstream against the current. The entire concept of dieting for fat loss is flawed. When you say you're going on a diet the underlying implication is that it's a temporary change and at some point you're going to have to go off' the diet. With this type of attitude, you're setting yourself up for failure right from the start. Permanent fat loss can't be achieved by going on and off diets. It can only be achieved by adopting new exercise and nutrition habits that you can maintain for the rest...

Dietary Carbohydrate

A negative correlation between total sugars intake and body mass index has been reported in adults (Dreon et al., 1988 Dunnigan et al., 1970 Fehily et al., 1984 Gibson, 1993, 1996b Miller et al., 1990). Increased added sugars intakes have been shown to result in increased energy intakes of children and adults (see Chapter 6) (Bowman, 1999 Gibson, 1996a, 1997 Lewis et al., 1992). In spite of this, a negative correlation between added sugars intake and body mass index has been observed in children (Bolton-Smith and Woodward, 1994 Gibson, 1996a Lewis et al., 1992). Published reports disagree about whether a direct link exists between the trend toward higher intakes of sugars and increased rates of obesity. Any association between added sugars intake and body mass index is, in all likelihood, masked by the pervasive and serious problem of underreporting, which is more prevalent and severe among the obese population. In addition, foods and beverages high in added sugars are more likely to...

Hygienicdietary habits

There is little doubt that the change in lifestyle of civilization was resulting in an increase in the prevalence of dental caries, referring mainly to the increase of the diet of soft foods that contain carbohydrates. The physical consistency of the diet food adhesives are more retentive than non-cariogenic. To know the habits of the patient is recommended to apply a questionnaire which included a series of questions regarding daily brushing and eating habits, focusing on behavioral risk factors for dental disease.

The Role of the Dietitian

Dietitians also have many other roles outside the health services. Increasingly practitioners work with government agencies, for example, in dietary surveys of the population, in execution and evaluation of nutrition intervention programs, and advising on the practical application of policy. In industry, they may work as advisors to food companies, wholesale and retail suppliers of food, and with companies producing specialized dietary products. In addition, dietitians are increasingly working independently as consultants, for example, in private practice, journalism, and sports nutrition. The scope of the dietitians' work is illustrated by Table 1, which lists the special interest groups for dietitians in the United Kingdom. Obesity Management

The Dietitians Role in Food Service

In the United States and countries that follow the US model hospital dietitians work in either administrative or clinical (therapeutic) areas. Administrative dietitians manage the provision of food services for all patients and staff. They are responsible for food production and quality control in the delivery of the hospital meal service as well as ensuring their nutritional adequacy. They are also often responsible for budgeting and staffing of the dietary departments and usually relate to other administrators and managers, having little or no direct contact with patients or medical staff. The clinical dietitian is the person who has direct contact with patients and the medical and paramedical staff involved in their care. In the United Kingdom, very few dietitians have overall responsibility for food service. However, there is usually close liaison between the dietitians and the catering manager in hospital practice to ensure the provision of nutritionally sound selective menus....

Weight Gain During Pregnancy

Infant mortality rate. 181 However, data from the Pregnancy Nutrition Surveillance System from the CDC showed that very overweight women would benefit from a reduced weight gain during pregnancy to help reduce the risk for high-birth-weight infants. 181 her BMI measured and recorded at the time of entry into prenatal care. For women with a BMI of less than 20, the target weight gain should be 0.5 kg (1.1 lb) of weight gain per week during the second and third trimester. For a woman whose BMI is greater than 26, the weight gain target is 0.3 kg (0.7 lb) per week during the last two trimesters. Women who are overweight or obese at the onset of pregnancy are advised to gain less total weight during the pregnancy (see box above). 182

AAssociation of Body Mass Index With Mortality

Many of the observational epidemiologic studies of BMI and mortality have reported a 'U-' or 'J-shaped' relationship between BMI and mortality. 28 Mortality rates are elevated in persons with low BMI (usually below 20) as well as in persons with high BMI. 28, 31 32 In some studies, adjustment for factors that potentially confound the relationship between BMI and mortality, such as smoking status and pre-existing illness, tends to reduce the upturn in mortality rate at low BMI ,31 but in a meta-analysis the higher mortality at low BMIs was not eliminated after adjustment for confounding factors. 32 It is unclear whether the elevated mortality observed at low BMI is due to an artifact of incomplete control for confounding factors, 285 inadequate body fat and or inadequate body protein stores that result from unintentional weight loss, 286 or individual genetic factors. Currently, there is no evidence that intentional weight gain in persons with low BMIs will lead to a reduction in...

Dietary Fiber and Protection Against Breast Cancer

A growing number of studies have reported on the relationship of Dietary Fiber intake and breast cancer incidence, and the strongest case can be made for cereal consumption rather than consumption of Dietary Fiber per se (for an excellent review see Gerber 1998 ). Between-country studies, such as England versus Wales (Ingram, 1981), southern Italy versus northern Italy versus the United States (Taioli et al., 1991), and China versus the United States (Yu et al., 1991), and one study within Spain (Morales and Llopis, 1992), all showed an inverse correlation between bread and cereal consumption and breast cancer risk. The findings of 378 DIETARY REFERENCE INTAKES Caygill and coworkers (1998) showed an inverse correlation between breast cancer incidence and both the current diet (p < 0.001) and the diet 20 years previously (p < 0.001). However, starchy root, vegetable, and fruit intakes were not related to breast cancer risk for either diet.

Goals of Obesity Prevention in Children and Youth

The goal of obesity prevention in children and youth is to create through directed social change an environmental-behavioral synergy that promotes Reduction in the incidence of childhood and adolescent obesity Reduction in the prevalence of childhood and adolescent obesity Improvement in the proportion of children meeting the Dietary Guidelines for Americans A healthy weight trajectory, as defined by the CDC BMI charts Because it may take a number of years to achieve and sustain these goals, intermediate goals are needed to assess progress toward reduction of obesity through policy and system changes. Examples include Increased number of new industry products and advertising messages that promote energy balance at a healthy weight mate aim of obesity prevention in children and youth, however, is to create, through directed social change, an environmental-behavioral synergy that promotes positive outcomes both at the population and individual levels. Box 3-1 summarizes these long-term...

Nondigestible oligosaccharides food intake and weight control a key role for gastrointestinal peptides

Reduction of food energy intake has been observed in several rat models (lean rats or mice, obese Zucker fa fa rats, high-fat-diet-induced obese mice) in which inulin-type fructans fibres, extensively fermented in the caeco-colon, were added to the diet. The decrease in food energy intake was not observed when fructans were substituted by non-fermentable DF (microcrystalline cellulose) (Daubioul et al. 2002). 3 Some fermentable DFs are able to increase proglucagon mRNA expression when given in high doses in the diet of dogs or rats (Reimer & McBurney 1996 Massimino et al. 1998). Are non-digestible oligosaccharides able to modulate gastro-intestinal peptides involved in appetite and body weight regulation We first compared the influence of inulin-type fructans having different DPs - namely OFS, OFS-enriched inulin (Syn) and high-molecular-weight inulin (Inu) - on daily energy intake, and GLP-1 and PYY production. It is important to note that the differences among inulin-type...

Dietary Management Dietary Guidelines

Dietary recommendations are as for the general population until research proves otherwise. There are no specific dietary guidelines for the woman pregnant with a Down's syndrome child or for the pregnant Down's syndrome woman. There are indications that antioxidant and essential fatty acid intake may be particularly important, and folic acid supplements beneficial, but dietary advice is currently the same as for other pregnant women. The situation is similar for infant feeding. Brain lipids in the human infant are known to change with changing intakes of fatty acids. The needs of a newborn with Down's syndrome for the long-chain polyunsaturated fatty acids docosahexenoic acid and arachidonic acid have not been determined. Since breast milk contains the preformed dietary very long-chain fatty acids that seem to be essential for the development of the brain and the retina, it seems prudent to encourage breastfeeding. The antioxidant defence system has a particularly important role in...

Dietary Interventions

During infancy and early childhood, caloric intake should conform to the current guidelines from the Nutrition Committee of the American Academy of Pediatrics. During the first 6 months of life, breast milk or infant formulas are primary nutritional sources, followed by introduction of solids at 5 or 6 months of age. Solid textures are gradually advanced based on oromotor skills (jaw strength and tongue mobility). Due to the high likelihood for development of hyperphagia and obesity, the majority of parents avoid exposure of the PWS child to high-calorie solids, desserts, and juices. Via close nutritional follow-up during the first 2 years, oral intake can be appropriately adjusted to maintain weight for height between the 25th and 80th percentiles. Caloric restriction under the guidance of an experienced nutritionist is employed only if weight gain becomes excessive. Nutritional strategies beyond the toddler years focus on avoidance of obesity. A number of studies have evaluated the...

Special Dietary Concerns in Cancer Survivors

There are many, many issues that may play a role in the nutritional state of a cancer survivor. The treatments may cause an increase or decrease in appetite. Nausea, vomiting, diarrhea, or constipation may be present. Intestinal surgery or removal of vital organs such as the pancreas can significantly impact one's diet and nutritional status. These problems need to be addressed individually based on the person's diagnosis, treatment, current weight, nutritional status, and other issues such as ongoing fatigue or nausea. If you have concerns about your diet or related matters, talk to your doctor and consider consulting a dietitian.

Hunger and Eating Behavior

Figure 3 Ratings of hunger made across the day by a group of obese women taking an appetite suppressant drug (dotted lines) or placebo (solid lines). Figure 3 Ratings of hunger made across the day by a group of obese women taking an appetite suppressant drug (dotted lines) or placebo (solid lines). In questioning the relationship between hunger and eating, we are also forced to place the action of hunger within a broader context of social and psychological variables that moderate food choice and eating behavior. Eating patterns are maintained by enduring habits, attitudes and opinions about the value and suitability of foods, and an overall liking for them. These factors, derived from the cultural ethos, largely determine the range of foods that will be consumed and sometimes the timing of consumption. The intensity of hunger experienced may also be determined, in part, by the culturally approved appropriateness of this feeling and by the host of preconceptions brought to the dining...

In addition to asking me to lose weight prior to surgery my doctor has asked me to quit smoking I dont think I can lose

Once again your doctor is not trying to sabotage your surgery. People who smoke do not do as well following any surgery requiring general anesthesia as nonsmokers. If you are a smoker it is likely that it will be more difficult to get you to breathe on your own following surgery than if you were a nonsmoker. Quitting even for a short period of time prior to surgery can make coming off the respirator easier. Quitting smoking on top of losing weight may seem like a major task, but you will be in much better shape for surgery if you do. If you remain off cigarettes long-term following surgery you will dramatically reduce your risk of heart disease, lung disease, and many forms of cancer. A smoke-free you, a lighter you, a healthier you. Think of how you can really change your life in the next six to twelve months.

Relevance of resistant starch to weight management

RS appears to play two roles with respect to weight management. Firstly there is a reduction in the digestible energy available from the RS compared with a readily digestible starch. The presence of RS in foods reduces their caloric density. Recently, research has demonstrated a second role for RS in energy metabolism and metabolic control. The lower glucose and insulin impact of RS causes changes in lipid metabolism that favor lower levels of lipid production and storage. In addition, RS is fermented within the large bowel by the indigenous colonic bacteria producing an important range of compounds called short-chain fatty acids (SCFAs). The amount and type of SCFA produced are proposed to affect carbohydrate and lipid metabolism in the body, particularly in the liver, muscle and adipose tissue. The known effects of RS in relation to weight management are listed in Table 8.1. Each of these aspects will be discussed later in this chapter.

Identification of other obesityassociated diseases

Obese patients are at increased risk for several conditions that require detection and appropriate management, but that generally do not lead to widespread or life-threatening consequences. These include Management options of risk factors for preventing CVD, diabetes mellitus, and other chronic diseases are described in detail in other reports. For details on the management of serum cholesterol and other lipoprotein disorders, refer to the National Cholesterol Education Program's Second Report of the Expert Panel on the Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel II ATP II) (1993). 142 For the treatment of hypertension, the National High Blood Pressure Education Program recently issued the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) (1997). 545 For the most recent recommendations about type 2 diabetes from the American Diabetes Association, see the...

Why do you think obese women are at greater risk of being depressed than obese men

The answer to this question is not clear. From my point of view it is remarkable that most obese people are completely psychologically intact. Obese people face prejudice and discrimination from an early age. Even at the tender age of six, children already harbor prejudice against overweight children. When asked to describe the silhouette of an overweight child, words such as lazy, stupid, ugly, and cheats were used. During adolescence, overweight girls are more commonly teased about their weight than overweight boys. Obese men and women often face prejudice at work, with many employers reporting reluctance or refusal to hire obese people. This bias against the obese appears to be directed more against women than men. As compared to their leaner friends, overweight men and women are less likely to marry. One study found that when compared to leaner women of comparable intelligence, overweight women completed fewer years of school and were less successful in their careers. There is...

Introduction of Dietary Therapy

For regular infant formula or breast milk. In some clinics, only phenylalanine-free formula is given for a few days so that blood phenylalanine will quickly decrease to an acceptable level. A prescribed amount of breast milk or standard infant formula, however, should be shortly introduced into the diet. Whole protein is needed to meet phenylalanine requirements and prevent phenylalanine deficiency, which will lead to muscle protein catabolism and inadequate weight gain. For formula-fed infants, both standard infant formulas and PKU medical foods are used in prescribed amounts and are bottle fed. Breast-feeding of an infant with PKU is possible and, as with all infants, should be encouraged whenever possible. Mature breast milk contains approximately 46 mg 100ml-1of phenylalanine compared to approximately 59 mg 100 ml-1 in cows' milk protein-based formula and approximately 88 mg 100 ml-1 in soy-based formulas. Therefore, breast-fed infants may initially have slightly lower plasma...

Food Guides versus Dietary Guidelines

Food guides are practical tools that people can use to select a healthful diet. Food guide recommendations, such as how many servings of grains to eat, are based on dietary guidelines that are overall recommendations for healthful diets. For example, the Dietary Guidelines for Americans include the recommendation that Americans choose a variety of grains daily, especially whole grains. To help people reach this goal, the USDA's Food Guide Pyramid is built on a base of grain foods and recommends six to eleven servings daily with several servings from whole grains. Thus, the Food Guide Pyramid supports the recommendations of the Dietary Guidelines.

The 2000 Dietary Guidelines for Americans

Aim for a healthy weight Be physically active each day salt, and sugar. There was heated debate among nutrition scientists when the Dietary Goals were published. Some nutritionists believed that not enough was known about effects of diet and health to make suggestions as specific as those given. In 1980, the first edition of Dietary Guidelines for Americans was released by the USDA and HHS. The seven guidelines were (1) Eat a variety of foods (2) Maintain ideal weight (3) Avoid too much fat, saturated fat, and cholesterol (4) Eat foods with adequate starch and fiber (5) Avoid too much sugar (6) Avoid too much sodium and (7) If you drink alcohol, do so in moderation. The second edition, released in 1985, made a few changes, but kept most of the guidelines intact. Two exceptions were the weight guideline, which was changed to Maintain desirable weight and the last guideline, in which alcohol was changed to alcoholic beverages. Following publication of the second edition of the Dietary...

Role of resistant starch in weight management 831 Weight management direct evidence

RS is by its very nature indigestible and so does not contribute directly to plasma blood glucose levels. Therefore, replacing digestible starch with RS is a natural fit for low-glycemic foods and diets. In a 2003 report, the World Health Organization (WHO) reviewed the strength of evidence on various factors that might promote or protect against weight gain and obesity. They assessed the totality of evidence, including randomized controlled trials (highest ranking), associated evidence and expert opinions. This group advised that based on the available evidence there is a 'possible' decreased risk of weight gain and obesity with low-glycemic-index foods. Few studies have looked at the impact of low-glycemic diets on weight loss or maintenance, by directly measuring body weight or body mass index (BMI). However, those that have generally indicate a positive role for low-glycemic diets. Ebbeling et al. (2003) compared low-glycemic-load dietary advice with low-fat dietary advice in a...

Dietary Reference Intakes

Dietary Reference Intakes (DRIs) are a set of nutrient reference values. They are used to help people select healthful diets, set national nutrition policy, and establish safe upper limits of intake. DRIs include four sets of nutrient standards Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). Starting in the mid-1990s, DRIs began to replace RDAs and Recommended Nutrient Intakes for Canadians, which had been the standards for the United States and for Canada, respectively. Not only is it important to know how much of a nutrient is needed for good health, it is also critical to know how much of a nutrient is too much. The UL is the highest intake of a nutrient that does not pose a threat to health for most people. Intake higher than the UL can cause adverse health effects, especially over time. see also Dietary Assessment Recommended Dietary Allowances Nutrients. Food and Nutrition Information Center,...

Requirements and Dietary Sources

Table 4 Recommended dietary intake Table 4 Recommended dietary intake In the US and Britain, as well as in other developed countries, most dietary iodine comes from food processing. Intake can vary, as illustrated in Table 6. Iodophors used as antiseptics in the dairy and baking industries provide residual iodine in milk and processed foods. In addition, iodine is present in several vitamin and pharmaceutical preparations.

Regulation of Dietary Supplements

Congress passed the Dietary Supplement Health and Education Act (DSHEA), which President Bill Clinton signed into law the same year. One provision of DSHEA clarified the definition for dietary supplements outlined above. DSHEA also mandated the establishment of the Office of Dietary Supplements (ODS) within the National Institutes of Health. The ODS coordinates research on dietary supplements and acts as a clearinghouse for regulatory issues. It also maintains an excellent resource for consumers, the International Bibliographic Information on Dietary Supplements (IBIDS), which is a database that contains citations published in scientific journals on the topic of dietary supplements. The public can access IBIDS on the ODS website. DSHEA established a new regulatory framework for supplement safety and for the labeling of dietary supplements by the U.S. Food and Drug Administration (FDA). Dietary supplements are regulated under food law, but with certain provisions that...

Dietary Trends American

Americans have become more aware of what they eat, and how it might affect their health. Concerns about the safety of the food supply are on the rise, and increasing nutritional awareness has led to an increase in vegetarian, organic, and health-food options in supermarkets. Lite food is in, and indulgence is out. But are Americans practicing what they preach A closer look at American dietary trends reveals that parts of the American diet are still lacking in nutritional quality, despite consumer demand for healthier options.

Recommended Dietary Intakes

The US and Canadian recommended iron intakes are intended to meet the requirements of 97.5 of the healthy population, replacing excreted iron and maintaining essential iron functions with a minimal supply of body iron stores. They also assume a relatively high bioavailability of the dietary iron. The recommended 8mg daily for adult men and postmenopausal women can easily be met with varied Western-style diets. More careful food choices are needed to obtain the 18 mg recommended to meet requirements for 97.5 of adult menstruating women. This higher recommendation reflects the high menstrual iron losses of some women the median iron requirement is 8.1 mg for menstruating women. During pregnancy, dietary iron recommendations are increased to 27 mg daily, based on the iron content of the fetus and placenta (approximately 320 mg) as well as the expanded blood volume associated with a healthy pregnancy. Meeting this recommendation generally requires iron supplementation. Supplementation...

Dietary Iron Food Sources

Typical Western diets contain approximately 6mg iron per 1000 kcal. Men and women consume approximately 16-18 and 12-14 mg daily, respectively. In the United States, 24 of dietary iron is supplied by breads, pasta, and bakery products. An additional 21 comes from (mostly fortified) cereal products. Other abundant dietary sources are red meats (9 from beef), poultry, legumes, and lentils. In countries such as the United States, fortification practices increase the influence of grain and cereal products as sources of iron. In countries without fortification to at least replace the iron lost during milling, the refinement of grain products considerably reduces dietary iron content. The populations of developing countries that eat little meat and do not include legumes or lentils as a dietary staple are at increased risk of inadequate iron intake.

Box 12 Does the Patient Want to Lose Weight

All patients who are overweight (BMI 25 to 29.9), or do not have a high waist circumference, and have few (0 to 1) cardiovascular risk factors and do not want to lose weight, should be counseled regarding the need to keep their weight at or below its present level. Patients who wish to lose weight should be guided per Boxes 8 and 9. The justification for offering these overweight patients the option of maintaining (rather than losing) weight is that their health risk, while higher than that of persons with a BMI < 25, is only moderately increased (page 62).

Protein consumption as a percentage of total calories

The baseline recommendation for people who participate in cardiovascular and resistance training exercise on a regular basis is 30 of total calories, although this percentage can vary depending on your needs. As we discussed in the chapter on carbohydrates, some people get better results with a lower carbohydrate intake. If carbohydrates are lower, then fats or protein must be higher. This is why, if you're carbohydrate sensitive, you might decrease your carbohydrates to about 40 and increase your protein to as much as 35-40 of your calories. Once you've selected your percentage of calories to come from protein, simply multiply the percentage of calories from protein by your total calories for the day the same way you did for fats and carbohydrates. This will tell you how many calories should Your optimal calorie intake to lose fat is 1700 calories per day To determine your protein intake, multiply your caloric intake by 30 1700 calories per day X .30 510 calories from protein There...

Portion Sizes Caloric Intake and Obesity

Scientists have begun to trace the link between portion sizes and increased obesity in the United States. According to the Centers for Disease Control and Prevention, between 1971 and 2000 American women increased the number of calories they consumed by 22 percent (from 1,542 to 1,877 per day), while men increased their intake by 7 percent (from 2,450 to 2,618 calories). Government recommendations, by contrast, are a mere 1,600 calories a day for women and 2,200 a day for men. Many of the additional calories consumed have come from carbohydrates, which has led some scientists to theorize that an increased emphasis on reducing saturated fat in diets led people to believe they could consume all the carbohydrates they wanted. Moreover, many more meals are now consumed outside the home, and serving sizes at national restaurant chains have become two to five times larger than they were in the 1970s. Cookbook publishers have followed suit by increasing portion sizes in recipes. During the...

Prevention of Further Weight Gain

Some patients may not be able to achieve significant weight reduction. In such patients, an important goal is to prevent further weight gain that would exacerbate disease risk. Thus, prevention of further weight gain may justify entering a patient into weight loss therapy. Prevention of further weight gain can be considered a partial therapeutic success for many patients. Moreover, if further weight gain can be prevented, this achievement may be an important first step toward beginning the weight loss process. Primary care practitioners ought to recognize the importance of this goal for those patients who are not able to immediately lose weight. The need to prevent weight gain may warrant maintaining patients in a weight management program for an extended period.

Dietary Mg Deficiency

Severe Mg deficiency is very rare, whereas marginal Mg deficiency is common in industrialized countries. Low dietary Mg intake may result from a low energy intake (reduction of energy output necessary for physical activity and thermoregulation, and thus of energy input) and or from low Mg density of the diet (i.e., refined and or processed foods). Moreover, in industrialized countries, diets are rich in animal source foods and low in vegetable foods. This leads to a dietary net acid load and thus a negative effect on Mg balance. In fact, animal source foods provide predominantly acid precursors (sulphur-containing amino acids), whereas fruits and vegetables have substantial amounts of base precursor (organic acids plus potassium salts). Acidosis increases Mg urinary excretion by decreasing Mg reabsorption in the loop of Henle and the distal tubule, and potassium depletion impairs Mg reabsorption. Mg deficiency treatment simply requires oral nutritional physiological Mg supplementation.

The truth about the glycemic index and fat loss

Although the GI has some useful applications, such as in post-workout and pre-workout carbohydrate choices, it's not the most relevant factor when it comes to fat loss. The GI is only one of many criteria you should consider in selecting your carbohydrates during a fat loss program. The GI is definitely a factor you can consider when deciding which carbohydrates to eat, but using the GI as your only criteria for choosing your carbohydrates is a mistake. If low GI foods were the key to fat loss, then you could eat ice cream, peanut M & M's, and sausages and you'd lose weight. There are more important factors than the GI. For maximum fat loss and optimal health, a much more relevant criteria than GI is whether your carbohydrates are natural or processed.

Smoking Cessation in the Overweight or Obese Patient

Cigarette smoking is a major risk factor for cardiopulmonary disease. Because of its attendant high risk, smoking cessation is a major goal of risk-factor management. This aim is especially important in the overweight or obese patient, who usually carries excess risk from obesity-associated risk factors. Thus, smoking cessation in such patients becomes a high priority for risk reduction. Evidence Statement Smoking and obesity together increase cardiovascular risk, but fear of weight gain upon smoking cessation is an obstacle for many patients who smoke. Evidence Category C. Rationale Both smoking and obesity are accompanied by increased risks for cardiovascular disease. Many well-documented health benefits are associated with smoking cessation, but a major obstacle to successful smoking cessation has been the attendant weight gain observed in about 80 percent of quitters. This weight gain averages 4.5 to 7 lb, but in 13 percent of women and 10 percent of men, weight gains in excess of...

Dieting and Eating Disorders

11 is easy for anyone who has been exposed to mass and popular culture in the U.S.A. in the past twenty years to believe that dieting is an exclusively female activity and that eating disorders only affect woman. Advertisements for weight-loss companies such as Weight Watchers and Jenny Craig primarily feature women, and young women have also been, until recently, the primary focus of discussions about anorexia and bulimia. Since the 1990s, however, diet companies, doctors, and the media have discovered that men deal with body-image problems and struggle with overweight and disordered eating as well. While men have actually been dieting and struggling with eating disorders for centuries, an increasing number of popular and professional publications in the past fif teen years have focused on the unique problems of obesity in men, male dieting, and men with eating disorders. In twentieth-century Western culture, overweight and eating disorders have largely been perceived as a female...

Secrets of low carb dieting How to get all the low carb benefits without the low carb side effects

There are three secrets to getting all the benefits of low carbohydrate dieting without all the side effects. The first is carbohydrate tapering, which is the practice of eating more carbohydrates early in the day and fewer later in the day. The second secret is using moderate carbohydrate reductions, not the removal of all carbohydrates. The third is carbohydrate cycling. When combined, the results of these three techniques can increase fat loss beyond your wildest dreams and expectations Lets take a closer look at each one.

Shifts in Dietary and Activity Patterns and Body Composition Seem to Be Occurring More Rapidly

The pace of the rapid nutrition transition shifts in diet and activity patterns from the period termed the receding famine pattern to one dominated by NR-NCDs seems to be accelerating in the lower and middle-income transitional countries. We use the word 'nutrition' rather than 'diet' so that the term NR-NCDs incorporates the effects of diet, physical activity, and body composition rather than solely focusing on dietary patterns and their effects. This is based partially on incomplete information that seems to indicate that the prevalence of obesity and a number of NR-NCDs is increasing more rapidly in the lower and middle-income world than it has in the West. Another element is that the rapid changes in urban populations are much greater than those experienced a century ago or less in the West yet Clearly, there are quantitative and qualitative dimensions to these changes. On the one hand, changes toward a high-density diet, reduced complex carbohydrates, increased added sugar and...

Dietary Changes Shift in the Overall Structure over Time

The diets of the developing world are shifting equally rapidly. There are no good data for most countries on total energy intake, but there are reasonable data to examine shifts in the structure of the diet. Food balance data were used to examine the shift over time in the proportion of energy from fat.

(Popkin BM (2002) The shift in stages of the nutrition transition in the developing world differs from past experiences Public Health Nutrition 5(1A) 205-214.)

Dietary Counselling and Fortification

Dietary counselling, usually provided by a dietitian, is an integral part of oral nutritional support. It includes advice on dietary fortification, which is often the first-line treatment of malnutrition in the home and other care settings. Counselling may involve advice on eating patterns (e.g., eating certain types of snacks at particular times of day) or addition of energy- and protein-rich food ingredients (e.g., cream, milk, oil, butter, sugar, and skimmed milk powder) to meals. Commercial energy- and protein-containing supplements can also be used to improve intake without substantially altering the taste of food and drink. The use of nutritionally fortified food snacks as part of the diet may improve both the intake and the status of micronutrients. However, the success of these dietary strategies is limited in patients with severe anorexia, those living in poverty and due to other social factors, and in those with inadequate motivation. Thus, patients may find it difficult to...

Causes and Mechanisms of Overweight and Obesity

The regulation of energy balance needs to be explored, including the neuroendocrine factors that control energy intake, energy expenditure, and the differentiation of adipose tissue resulting from excess calories. The genes that are important in human obesity need to be identified. These include those that alter eating and physical activity behaviors, those that affect thermoge-nesis, and those associated with the comorbidi-ties of obesity. The roles of environmental and behavioral influences on metabolic factors important in obesity, as well as gene-environment interactions, need to be studied. Predictive factors should be examined to identify who is most at risk of developing obesity, and whether there are critical periods of life when these factors are most operative. In addition, the influence of the intrauterine environment on the development of obesity needs to be investigated, particularly to determine whether early deprivation leads to a later propensity for overweight and...

Individual Nutritional Status and Dietary Intake Data

Information on the dietary intake and nutritional status of individuals in a population is essential for monitoring trends in these indicators over time and in response to political and environmental changes, as a means of identifying groups for intervention, and to assess the impact of interventions on nutritional status of the population. Although dietary intake and simple anthropometric measurements, such as weight and height, have often been the focus of health and nutrition surveys, it is essential that other indicators of nutritional status such as micronutrient deficiencies also be documented because they continue to be important public health problems in most developing countries. Furthermore, as discussed previously, information on factors that are direct (e.g., the prevalence of infections) and indirect (e.g., maternal education and family socioeconomic status) causes of nutritional problems increases the usefulness of nutritional surveillance information for policymakers....

Body Composition in Childhood and Definition of Childhood Obesity

However, the percentage of body weight that is fat varies normally throughout childhood (Table 1). The infant is born with modest amounts of fat. More than 50 of the energy in breast milk comes from fat, and young infants lay down fat very rapidly so that in the 4 or

Assessment of Overweight and Obesity in Childhood

Definition of overweight obesity from weights in relation to height and age. In adults, body mass index (BMI weight in kg (height in m)2) is used as a proxy for fatness. A BMI > 25kg m2 (overweight) is associated with a significant increase in the risk of mortality and with an increased prevalence of complications of obesity. In childhood, BMI varies with age in a nonlinear fashion. Since at different ages children tend to retain their growth positions in relation to those of their peers, the International Obesity Task Force has defined childhood overweight and obesity as those points on the BMI centile, or standard deviation, for age distribution charts that, if followed to the age 18, would meet the adult cutoff points for overweight and obesity (BMI, 25 and 30kg m2). This definition involves no direct assessment of body fat or lean body mass for age. It needs evaluating against other evidence of excessive body fat and the prevalence of complications of obesity, particularly since...

Preventing weight Gain with Internet Programs

Two of the ten leading health indicators of Healthy People 2010 (U.S. Department of Health and Human Services USDHHS , 2000) focus on weight management and physical activity. Decades of research show the central role of these health behaviors for disease prevention (Koplan & Dietz, 1999) given their association with heart disease, particularly, the association with central obesity (Alexander, 2001 Melanson, McInnis, Rippe, Blackburn, & Wilson, 2001 Pi-Sunyer, 2002) the enormous burden placed on the health care system by the diseases associated with overweight and obesity (Manson & Bassuk, 2003 Must et al., 1999). Most Americans and people in other developed countries are overweight (body mass index BMI > 25) or moderately obese (BMI > 30) and are sedentary (Fielding, 2001 Flegal, Carroll, Ogden, & Johnson 2002 Hedley et al., 2004 Institute of Medicine, 2002 Rafferty, Reeves, McGee, & Pivarnik, 2002 USDHHS, 2002). Hill, Wyatt, Reed, and Peters (2003) predict by 2008...

Dietary Management

The amount of snacking will probably be appropriate (Table 3). There is no consistent evidence that reduction of any particular energy source is more effective than any other in promoting fat loss, so 'balanced diets' conforming to the 'healthy diet' principles of WHO and many governments should be followed.

Prevention of Obesity in Childhood

The prevention of obesity involves creating lifestyle changes at the family, school, community, and national level. Initiatives need to be affordable and sustainable so that those most at risk of obesity are reached and feel ownership of community programmes. Table 5 suggests changes needed to reduce the obesogenic factors in the current Westernized environment. If the obesity epidemic is to be halted, governments and international industries have to work with communities to bring about effective change.

Dietary Fat A Good Thing in Moderation

Despite fat's bad reputation, it is a very important nutrient. Dietary fat plays many critical roles in the body, such as providing essential fatty acids, fat-soluble vitamins, and energy. It also serves structural functions in hormones and in cells. Most government health agencies and professional health organizations encourage people five years old and older to eat a diet with less than 30 percent of total calories from fat, and less than 10 percent of that from saturated fat.

Objectives of Obesity Prevention

There remains a great deal of confusion regarding the appropriate objectives of an obesity prevention program. It is often assumed that to be effective, any intervention to address the problem of excess weight in the community should result in a reduction in the prevalence of overweight and obesity. However, such an objective is unrealistic and may be counterproductive. Most communities are experiencing significant increases in the average weight of the population as a result of a sizeable energy surplus resulting from reduced energy expenditure combined with an increased energy intake. This is leading to rapidly escalating rates of overweight and obesity. To reverse this trend will require not only the removal of this energy surplus but also the creation of a negative energy balance that will need to be maintained by the whole population for a significant period of time. Few (if any) interventions are capable of reducing energy intake, or increasing energy expenditure sufficiently,...

Causes of the Obesity Epidemic

There are a number of plausible explanations for the growing epidemic of overweight and obesity. Genetic factors play a role. Some people are more susceptible to weight gain than other people given conducive environmental circumstances (Friedman, 2003). Changes in environmental and behavioral factors affect the entire population and likely most affect those at genetic risk (Booth, Chakravarthy, Gordon, & Spangenburg, 2002 Booth, Gordon, Carlson, & Hamilton, 2000 Chakravarthy and Booth, 2004). Technological changes reduce the necessity of physical activity in jobs and other aspects of daily life (Hill & Melanson, 1999 Hill & Peters, 1998). New cities and most suburbs are designed for cars and reduce the need for walking (King, Bauman, & Abrams, 2002 Reid, Schmid, Killing-sworth, Zlot, & Raudenbush, 2003). Few people consistently exercise or engage in leisure-time physical activity and the small percentage of active people may be declining (Booth et al., 2002)....

Importance of Weight Gain Prevention in Adults

There are a number of important reasons why it is preferable to focus on weight gain prevention as the key individual and population objective of obesity prevention initiatives in adults (Box 1). The association between elevated body mass index (BMI) and increased risk of ill health is clear and consistent. Box 1 Why focus on weight gain prevention Weight gain in adulthood carries an independent risk of ill health. Riskforchronic disease begins to increase from lowBMI levels and significant weight gain can occur within normal limits. Extended periods of weight gain are difficult to reverse. Weight gain in adulthood is mostly fat gain. The relationship between absolute BMI and health risk varies with age and ethnicity but no such variations occur in the relationship between weight gain and ill health. A focus on weight gain prevention avoids exacerbation of inappropriate dieting behaviors. It avoids reference to poorly understood terms such as 'healthy weight.' However, research has...

Who Should Obesity Prevention Strategies Target

Deciding where to invest limited time and resources in obesity prevention is a difficult task but finite health resources make this a necessity. WHO has identified three distinct but equally valid and complementary levels of obesity prevention (Figure 1). The specific 'targeted' approach directed at very high-risk individuals with existing weight problems is represented by the core of the figure, the 'selective' approach directed at individuals and groups with above average risk is represented by the middle layer, and the broader universal or populationwide prevention approach is represented by the outer layer. This replaces the more traditional classification of disease prevention (primary, secondary, and tertiary), which can be confusing when applied to a complex multifactorial condition such as obesity. Figure 1 Levels of obesity prevention intervention. (Adapted from Gill TP (1997) Key issues in the prevention of obesity. British Medical Bulletin 53(2) 359-388.) Figure 1 Levels of...

Can Fat Substitutes Help to Reduce Dietary

Fat-modified foods can fit into a healthy eating plan. According to the American Dietetic Association, they offer a safe, feasible, and effective means to maintain the palatability of diets that are controlled in fat or calories. But they are only one of the many tools that can be used to achieve nutrition goals. Foods with fat substitutes should be consumed as part of an overall healthful eating plan, such as that outlined in the Dietary Guidelines for Americans. see also Artificial Sweeteners Dietary Guidelines for Americans Fats.

Obesity Prevention Programs

A number of systematic reviews have assessed the current scientific literature on programs addressing the prevention of obesity in both children and adults and have identified only a limited number of evaluated programs. The reviews concluded that there was simply too small a body of research conducted in a limited number of settings to provide firm guidance on consistently effective interventions. However, reviews of childhood obesity prevention initiatives indicated that certain approaches appear to be associated with greater success. Intensive intervention in small groups was a successful management strategy in children, as was involving the entire the family. Reducing levels of inactivity was successful at both treating and preventing weight gain. Some interventions that increased time spent in formal physical activity were successful in controlling weight gain, but generally multicomponent programs that addressed a range of strategies were deemed to hold the most promise. There...

Obesity is a chronic and relapsing disease hence, it is the long-term efficacy of these dietary strategies in maintaining lowered weight (and minimizing the risk of diet-related chronic diseases) that is of fundamental importance.

Clinical and Public Health Approaches to the Obesity Epidemic

Overweight and obesity are addressed by both clinical treatments and public health approaches. We will briefly describe these approaches and describe an alternative that bridges clinical and public health approaches. Higher dose, longer term behavioral interventions focusing on dietary changes and physical activity via lifestyle changes show modest weight loss (Andersen, Wadden et al., 1999 Anderson, Konz, Frederich, & Wood, 2001 Diabetes Prevention Program Research Group, 2002 Jeffery et al., 2000 Lowe, Miller-Kovach, & Phelan, 2001 Marcus, Dubbert, et al., 2000 Perri & Corsica, 2002 Riebe et al. 2003 Wing, 1999, 2000 Wing, Voor-hees, & Hill, 2000). Weight loss of 5-10 that is maintained favorably impacts risk factors for heart disease (e.g., blood pressure and lipids), cancers (e.g., body fat), and diabetes (e.g., insulin resistance see Perri & Corsica, 2002). Some people are successful in long-term weight loss on their own (McGuire, Wing, & Hill, 1999 Wing &...

Drug Treatment of Obesity Rationale

Diet restriction even when combined with behavioral therapy and increased exercise is often unsuccessful in achieving weight loss and maintenance in obese subjects. Obesity is not a single disorder but a heterogeneous group of conditions with multiple causes. Although genetic differences are of undoubted importance, the marked rise in the prevalence of obesity is best explained by behavioral and environmental changes that have resulted from technological advances. In such circumstances, it is appropriate to consider pharmacological treatment as an adjunct to the other treatment modalities. In broad terms a pharmacological agent can cause weight loss by reducing energy intake or absorption and by increasing energy expenditure. Current drug treatment of obesity is directed at reducing energy food intake either by an action on the gastrointestinal system or via an action through the central nervous system control of appetite and feeding.

Types of Obesity Surgery

At least 30 surgical techniques have been developed for the treatment of obesity. Superficial cosmetic removal of adipose tissue (liposuction) will not be considered because it has no lasting benefit and it is not regarded as a treatment for obesity. Jaw wiring (intermandibular fixation) can restrict intake of food but it is no longer recommended for surgical treatment of obesity due to a lack of long-term efficacy. The operative procedures currently used for the surgical treatment of obesity are outlined below. Able to lose weight prior to surgery Have no evidence of psychiatric disease or maladaptive eating behaviors Absence of endocrine disorders that can cause morbid obesity Gastric banding involves the external 'pinching off' of the upper part of the stomach with a band usually made of Dacron. A modification of the gastric banding is an inflatable circumgastric band attached to a subcutaneous reservoir that allows access by a hypodermic syringe to inject or withdraw fluid thereby...

Efficacy of Surgical Treatment for Obesity

Surgery is usually successful in inducing substantial weight loss in the majority of obese patients. This is achieved primarily by a necessary reduction in calorie intake. In a review of RCT comparing different treatment strategies of obesity, surgery resulted in greater weight loss (23-28 kg more weight loss at 2 years) with improvement in quality of life and comorbidities. The Swedish Obese Subjects (SOS) study demonstrated long-term beneficial effects on cardiovascular risk factors. The development of type 2 diabetes mellitus is most favorably influenced with a 14-fold risk reduction in those obese patients undergoing surgical treatment.

Multidisciplinary Approach to the Management of Overweight and Obesity

Published evidence confirms that patients do better whatever the treatment when seen more frequently and for a greater length of time. Moreover, strategies that involve expertise incorporating dietetic, behavioral, and exercise experts as well as physicians and surgeons are also more successful in sustaining weight loss. This underlines the importance of a multidisciplinary approach. Treatment programs should include a system for regular audit and the provision for change as a result of the findings. Any center that claims to specifically provide expertise in weight management should incorporate the essential elements outlined in Table 7.

Preventing Weight Gain

Hill et al. (2003) and Jeffery and French (1999) point out that the annual mean weight gain across the population is small. Hill et al. (2003) estimated that among people 20-40 years old, the annual weight gain is 1.8-2.0 pounds year. Data from the CARDIA study (Lewis et al., 2000), which investigated weight changes in African American and Caucasian males and females over 15 years, indicate that overall weight gain during young to middle adulthood averages 1.5 pounds year. The largest weight gain occurs in the 20s and then levels off. Weight gain is due to a small energy imbalance (energy gap) over many years. Hill et al. (2003) estimated mean energy accumulation accounting for both the metabolic costs of storing energy and considering their estimates for the 90th percentile for excess energy storage is only about 50 kcal day (50 calories per day). Many people are consuming on average as little as 100 kcal more than expended each day to account for storage of 50 extra kcal per day...

Why am I losing weight

About 10 of people with PD lose weight. This usually happens late in PD, but weight loss may occur early. Weight loss occurs with decreased food intake, increased metabolism, or both. In PD, weight loss may occur for the following reasons It's thought but not proven that in PD the hypothalamus (a region in the brain that controls all the glands and the ANS) is reset and causes the body to burn calories more quickly. If you're losing weight, eating well, and don't have a marked tremor or dyskinesia, causes of weight loss other than PD must be considered. These include cancer depression diabetes drugs, such as high doses of Sinemet, amphetamines, cancer chemotherapy drugs, cocaine, laxatives, lithium, or thyroid drugs diseases of the stomach (ulcers) or intestines (colitis, diverticulitis) infections, including AIDS and tuberculosis and thyroid disease, or overactivity. A useful rule in PD is to weigh yourself regularly and to keep a record of your weight. Then, if you see a downward...

Dietary Guidelines for Health Function and Disease Prevention

Concomitant to recommendations for daily nutrient intake based on requirements, guidance and orientation for the pattern of selection of nutrient sources among the food groups have emerged as so-called 'dietary guidelines.' They are often accompanied by an icon or emblem, such as a pyramid in the US, a rainbow in Canada, and a Hindu temple in India, each of which expresses the general tenets of the dietary guidelines in a visual manner. A quantitative prescription, or some notion of balance among foods and food groups, is the basis of dietary guidelines there is also often a proscription for foods considered to be harmful or noxious. The additional susceptibility of older persons to chronic degenerative diseases makes adherence to these healthful dietary patterns, throughout the periods in the life span preceding the older years, more relevant. Recent epidemiological research has shown that compliance or behavior concordant with healthy eating guidelines are associated with lower...

Barriers to Meeting Recommended Nutrient Intakes and Healthful Dietary Intake Patterns by Older Persons

The late Professor Doris Calloway, in the early 1970s, commented ''People eat food, not nutrients.'' This highlights the paradoxes in considering and enumerating the objectives of dietary intake at the level of the Elderly persons face a number of challenges in meeting their recommended nutrient intakes. In the first instance, they are likely to be those with the least sophisticated or available knowledge of the nutrients required and the food sources to provide them. The social, economic, and physiological changes imposing on the lives of persons surviving to advanced age pose logistical problems for their selecting and purchasing a diet. Economic dependency and the limited incomes of older persons may restrict their access to high-quality foods. Social isolation, depression, and impaired mobility, as well as chewing difficulties may limit the variety of items included in the diet with advancing age. In some circumstances, it may be that free-living and independent elders are...

Dietary Intake and Body Mass

Dietary Body mass index individual's body weight is one of the strongest determinants of bone mass because of the skeleton's responsiveness to the load that is placed on it. Individuals with small body frames or those who are excessively thin have an increased risk of osteoporosis due to a lower overall skeletal reserve to draw on for calcium needed to offset the annual loss of bone that occurs later in life. At the extreme end of this spectrum, individuals with anorexia nervosa are at risk of osteoporosis because of alterations in hormonal status and amenorrhea in addition to insufficient dietary intake of nutrients required for bone health. Although overall caloric intake impacts body weight, many nutrients and dietary components have been studied in relation to their impact on bone health (Table 1). Several of these key nutrients and components of the diet and their roles in bone health and skeletal homeostasis are detailed next.

Dietary Intake and Energy Expenditure

Dietary Intake Reduced dietary intake is an important contributor to malnutrition in children with CLD. Fatigue, anorexia, nausea, vomiting, diarrhea, altered or reduced ability to taste, and early satiety may all contribute to decreased ingestion of food. Organomegaly and ascites can further compromise dietary intake by reducing gastric capacity. Additionally, many diet modifications, for example sodium, fluid or protein restrictions, make food even more unpalatable. These dietary restrictions are imposed on patients with relatively high risks of fluid overload and encephalopathy, which, when left untreated, can lead to serious irreversible defects 8 . Recently, Watanabe et al. 14 found that bile acids induce energy expenditure by promoting intracellular thyroid hormone activation. In this study, mice were fed a bile acid (cholic acid)-containing high fat diet. These mice showed subsequent reduction in weight gain, white adipose tissue weight and brown adipose tissue weight compared...

Introduction role of dietary and supplementary calcium in weight control

The recommended daily intake of calcium (1000 mg day for most adults, 1200 mg day for pregnant women) has been set to meet the requirements of bone-health and the prevention of osteoporosis. Beyond this, calcium plays an essential role in numerous other vital functions regulation of cell membrane fluidity and permeability, nerve conduction, muscle contraction and blood clotting. Calcium has anti-hypertensive properties and the consumption of calcium in sufficient amounts may reduce the risk of colon cancer. Various studies over the last few years have shown that increased calcium intake can significantly fight overweight and obesity. In the following sections the question will be addressed as to whether a role for calcium in weight control is substantiated by facts gained from epidemiological studies and the results of in vitro, animal and human intervention studies, showing either a positive role for calcium in lipid metabolism and weight control, or no effect at all. In order to...

Uses of the Food Guide Pyramid

Individuals can use the Pyramid educational materials to plan a diet that contains all needed nutrients and is moderate in fat and saturated fat. This is important in the United States, where the major causes of death, such as heart disease, are related to diets high in fat, especially saturated fat. Obesity is also a major health concern in the United States. Although physical activity is a critical component of weight management, food intake also plays a role in energy balance. The Food Guide Pyramid educational materials provide serving sizes and a recommended number of servings for people of different ages and activity levels. This guide can help people learn to eat reasonable amounts of food in a country where large portion sizes are the norm.

Dietary Sources of Phosphorus

A conservative estimate is that most adults in the United States consume an extra 200-350 mg of phosphorus each day from these sources and cola beverages. Therefore, the total phosphorus intakes for men and women are increased accordingly. Because the typical daily calcium intake of males is 600-800 mg and that of females is 500-650 mg, the Ca P ratios decrease from approximately 0.5-0.6 to less than 0.5 when the additive phosphates are included. As shown later, a chronically low Ca P dietary ratio may contribute to a modest nutritional secondary hyperparathyroidism, which is considered less important in humans than in cats. Table 1 provides representative values of calcium and phosphorus in selected foods and the calculated Ca P ratios. Only dairy foods (except eggs), a few fruits, and a few vegetables have Ca P ratios that exceed 1.0.

Determining the role of calcium in weight control

Recently, an anti-obesity effect of dietary calcium has been postulated (for reviews see Teegarden (2003), Zemel (2002) and Zemel and Miller (2004a)). Although first observations in rats and men showing an inverse relation between calcium intake, adipocyte intracellular calcium and obesity had already been published at the end of the 1980s (Draznin et al., 1988), this idea has never been more popular in the scientific community since the publication of the papers of Zemel and colleagues (Xue et al., 1998, 2001, Zemel et al. 1995, 2000). These publications were based to a major extent on investigations on obese and insulin-resistant mutant mice ('agouti mouse') and led to an intensive re-examination and extended interpretation of data from several epidemiological studies. 11.2.1 Epidemiological and intervention studies showing a role for calcium in weight management Data from the US NHANES III (Third National Health and Nutrition Examination Survey), the CSFII study (Continuing Survey...

Dietary versus supplementary calcium and weight control

On the other hand, these studies also show that calcium has an anti-obesity effect of its own that is independent from other components of the diet. However, based on the results of the available positive studies and without exact knowledge of the mechanism, it is not possible to answer the question as to what extent this calcium effect is independent from the level of the 'normal' dietary calcium intake. According to our current understanding it could make sense to increase calcium intake above that of the recommended intake by using calcium-fortified food and or calcium supplements in order to optimise intake for an anti-obesity effect. Independent of the answer to these questions, some quantitative information can be given to the extent of the anti-obesity effects of calcium. A quantitative re-analysis of the data from Davies and Heaney (Davies et al., 2000), using simple bivariate and multiple regression models, revealed The actual importance of these effects becomes evident...

American physician credited with first suggesting calorie counting as a means of gaining and losing weight

Peters served as chairman of the Public Health Committee of the California Federation of Women's Clubs in Los Angeles. She is the author of the first bestselling American diet book, Dieting and Health With Key to the Calories, published in 1918. Framed as a response to World War I (and dedicated to Herbert Hoover, whose claim to fame at that point was that he fed starving Belgium) it set out obesity as a crime to hoard food for which one would be fined or imprisoned. How dare you hoard food when our nation needs it (Peters 1918 12). The book is said to have sold 2 million copies and was published in more than fifty-five editions by i939. As the model for recent modern diet books, it was directed and marketed primarily to women, written in a popular style, and included testimonials of successful weight loss. Unlike modern diet books, however, Peters included suggestions for weight gain as well as beauty tips, such as how to eliminate wrinkles. Her key to the calories was an extensive...

Using the Estimated Average Requirement and the Recommended Dietary Allowance

The Estimated Average Requirement (EAR) estimates the median of a distribution of requirements for a specific life stage and gender group, but it is not possible to know where an individual's requirement falls within this distribution without further anthropometric, physiological, or biochemical measures. Thus from dietary data alone, it is only possible to estimate the likelihood of nutrient adequacy or inadequacy. Furthermore, only rarely are precise and representative data on the usual intake of an individual available, adding additional uncertainty to the evaluation of an individual's dietary adequacy. An approach for using data from dietary records or recalls to estimate the likelihood that an individual's nutrient intake is adequate is presented in Dietary Reference Intakes Applications in Dietary Assessment (IOM, 2000). This approach is appropriate for nutrients with symmetrical requirement distributions, which is thought to be true for all macronutrients in this report for...

Apple Pomace As A Dietary Fortificant

Apple pomace, a dietary-rich ingredient, is considered as a potential food ingredient for food products because of its well-balanced proportion of soluble and insoluble fractions of dietary fiber. Apple pomace has better quality dietary fiber due to the presence of bioactive compounds such as polyphenols, flavonoids, and carotenes. Concentrates from apple pomace as such and after processing have been evaluated for their functional properties.

Variability in Weight Gain

The BMI-specific target ranges for pregnancy weight gain are relatively narrow, but a very wide range of gain actually occurs. In a California study, for example, only 50 of the mothers who had an uncomplicated pregnancy with a normal birth-weight infant gained the recommended 12.5-18 kg, with the remainder gaining more or less. Since a substantial amount of the variation in weight gain is due to physiological variability and prepregnancy BMI, deviation from the recommended range may not necessarily be cause for concern. However, it is especially important to assess the dietary patterns and other behaviors of women whose weight gain is unexpectedly high or low. The IOM Implementation Guide for weight gain recommendations provides helpful information on the assessments that should be used.

Maternal Weight Gain and Birth Weight

Inadequate weight gain is associated with poor fetal growth even when the contribution of fetal weight and factors such as length of gestation are taken into consideration. Birth weight is an important determinant of child health and survival low-birth-weight (< 2.5 kg) infants are 40 times more likely to die in the neonatal period. Low weight-for-length at birth may be a risk factor for chronic disease in later life. It has been estimated that in women with a normal prepregnancy BMI, each kilogram of total pregnancy weight gain has an average effect on birth weight of 20 g. In California, women with pregnancy weight gains below recommendations had a 78 higher risk of the infant being born small, whereas women who gained in excess of recommendations were twice as likely to give birth to a large infant. As noted previously, maternal BMI at conception is strongly inversely related to expected pregnancy weight gain. Nevertheless, heavier women still tend to deliver heavier infants...

Pregnancy Weight Gain and Postpartum Risk of Obesity

On average, well-nourished women retain relatively little weight approximately 1 year postpartum (approximately 0.5-1.5 kg). Delivery is followed by a rapid loss of weight in the subsequent 2 weeks due to fluid loss. This is followed by a slower rate of loss for the next 6 months, so a complete return to preconception weight should not be expected in less time than this. In general, weight still retained at 1 year postpartum is unlikely to be lost without lowering intake and or increasing physical activity. If weight retention is substantial, it can add to the risk of obesity in the longer term, and obesity is a major public health concern in many countries. The relatively low average weight retention postpar-tum obscures the fact that many women do retain an excessive amount of weight. Those who retain most are likely to have gained large amounts of weight during pregnancy. At 10-18 months postpartum, weight retention was 2.5 kg for women who gained more than the IOM recommendation...

Dietary Guidelines for Pregnancy

In general, pregnant women should follow the dietary advice provided by reputable national or professional organizations for all members of the public. For example, the Dietary Guidelines of the US Department of Agriculture include advice to eat a variety of foods maintain or improve your weight and choose a diet low in fat, saturated fat, and cholesterol and moderate in sugars, salt, and sodium. However, advice to control or maintain body weight, or to consume alcohol in moderation if it is consumed, is inappropriate in pregnancy. Specific guidelines for pregnant women are available and provide more specific information on recommended nutrient intakes, weight gain, the need for vitamin mineral supplements, activity, and the use of alcohol and other substances. Examples include a position paper by the American Dietetic Association and guidelines from the March of Dimes. Most of the increased requirements for nutrients during pregnancy can be met primarily by an adequate dietary...

The ultimate secret to fat loss

Aerobic exercise is the real secret to losing body fat. Except for the genetically gifted people who appear to have been born ripped, it's extremely difficult - if not impossible - to lose fat permanently with diet alone. Dieting without exercising is one of the major reasons for the 95 failure rate of weight loss programs today. The reason is simple A decrease in calorie intake, if extreme and or prolonged, slows down the metabolism while an increase in activity can actually speed up your metabolism. As you learned in chapter seven, eating (and eating often) boosts your metabolic rate. So by doing regular aerobic exercise and eating more often, you get a double boost in metabolic rate Most people are afraid to increase calories and increase cardio simultaneously because they figure the two will somehow cancel each other out. Surprisingly, the opposite is true they enhance each other.

Vulnerable to losing weight

Joe was a little subdued when I drove him back to The Great Barn on Monday evening. We had all had such a lovely weekend and he clearly wasn't looking forward to being back under the strict supervision of the staff at The Great Barn. As soon as we arrived one of the members of staff on duty took me aside to ask for feedback of our weekend. I gave her a brief outline of events and admitted that Joe had probably been a little more active than he should have been, playing football and cricket with his friends and bouncing on the trampoline for a short period with his brother. This didn't go down too well and I was given quite a lecture about how Joe should only be doing a very limited amount of gentle activity and that he was still very vulnerable to losing weight. There seemed little point in arguing, so I simply agreed that we would be very careful in future. However, deep down I felt that Joe had had an excellent weekend and become much stronger mentally. He had coped extremely well...

Confronting the Childhood Obesity Epidemic

Obesity in U.S. children and youth is an epidemic characterized by an unexpected and excess number of cases on a steady increase in recent decades. The epidemic is relatively new but widespread, and one that is disproportionately affecting those with the fewest resources to prevent it. Although it does not have the exotic nature or immediate mortality of severe acute respiratory syndrome, anthrax, or Ebola virus, it is harming a much broader cross section of our young people and may significantly undermine their health and well-being throughout their lives. Obesity can affect a child's health immediately through physical or psychological conditions such as type 2 diabetes, hypertension, steatohepatitis, depression, and stigma. Obesity can also affect a child's health in the longer term with additional illnesses that include arthritis, cancer, and cardiovascular disease. Infectious disease epidemics require and usually receive immediate highlevel attention, with resources invested to...

Smoking Cessation And Weight Gain

It is not clear whether weight gain during cessation is temporary or permanent, although the majority of studies indicate that some weight gain (about 5 pounds) is likely to be long-term. Although the mechanisms responsible for the weight gain are not clear, a number of hypotheses have been set forward. These include a metabolic effect for smokers this is supported by research indicating that smokers and nonsmokers have few differences in the amount of calories consumed. Another hypothesis is that smoking lowers the body's ''set point'' for weight and smoking cessation raises that set point to be equivalent to that of nonsmokers. A third hypothesis is based on the observation that an increase in caloric intake occurs in those who stop smoking, and increased consumption may be responsible for the weight gain. Although weight gain is likely to accompany cessation, actual weight gain during smoking cessation does not appear to be related to cessation outcomes. Nevertheless, in reaction...

Strategies Of Weight Control During Cessation

The focus of weight control strategies during cessation has revolved around diet, exercise, and most recently, pharmacologic agents. Weight control programs through behavioral self-management of dietary intake have been largely ineffective. In two large randomized trials of behavioral weight management during cessation, the standard care (control) groups with no weight control intervention had better cessation outcomes than the groups that received the behavioral intervention. One of the studies, however, reported that the amount of weight gained was lower for individuals receiving the dietary weight control intervention than individuals not receiving it. In recent years, a number of research studies examining the effect of physical exercise on weight control during cessation have been conducted. The majority of these studies have been conducted with women. The largest randomized study to date found that women who participated in exercise as well as a smoking cessation program were...

How to double your rate of fat loss with more frequent aerobic workouts

How would you like to learn a way to double your fat loss in the next seven days It's really quite simple To burn more fat you have to burn more calories. Most beginners start off with three days a week of cardio training. Usually they see good results initially because their bodies aren't accustomed to exercise and any increase in activity above no activity will always produce some results. This is why Because three days a week is for beginners, health, or maintenance. If you want twice as much fat loss and you want it twice as fast, double your cardio. Suppose you burn 400 calories per workout for three workouts per week. That's a total of 1200 calories per week burned. If you doubled that to six days per week at 400 calories per workout, you would burn 2400 calories. YOU JUST DOUBLED YOUR FAT LOSS EVERY WEEK That was a real no-brainer, wasn't it YOU JUST TRIPLED YOUR FAT LOSS By the way, this kind of cardio training is how I reach 3 - 4 body fat for competitions I do approximately...

Regulation of Prostaglandin and Leukotriene Synthesis by Dietary Fatty Acids

The diverse physiologic and pathologic functions mediated by eicosanoids highlight the importance of their fatty acid precursors in the diet. Unlike cellular proteins that are genetically predetermined, the PUFA composition of cell membranes is dynamic and is pivotally dependent on dietary intake. The typical Western diet is high in the n-6 family of PUFA (up to 25-fold more n-6 fats than n-3 fats are consumed). This predominance of n-6 fat is due to the abundance in the diet of the 'parent' 18-carbon PUFA linoleic acid (LA 18 2 n-6), which is present in high concentrations in corn, soy, safflower, and sunflower oils. Once ingested, LA can be converted to AA by a series of elongation and desaturation enzymes (Figure 6). Hence AA is the predominant PUFA of membrane The enzymes involved in the metabolism of the 20-carbon PUFAs to PGs and LTs can use either n-9 (eicosatrienoic acid EtrA 20 3), n-6 (arachidonic acid AA 20 4), or n-3 (eicosapentaenoic acid EPA 20 5) PUFAs as the substrate...

Dietary Protein Allowances and Implications of Adaptation

The Estimated Average Requirement (EAR) defines the notional mean requirement for the population group. The Recommended Nutrient Intake (RNI) is defined according to the range of interindividual variability and is two standard deviations above the EAR. The RNI (or Recommended Dietary Allowance) is thus an intake that will meet the requirement of most of the population assuming normal distribution of requirements and is therefore a 'safe allowance.' The Lower Nutrient Reference Intake, which is two standard deviations below the EAR, defines the lowest intake that will meet the requirement of some of the population. It follows from these definitions that in deriving dietary allowances from nitrogen balance studies, the variability in the reported values is very important since this is used to set the RNI. The currently agreed value is based on an EAR of 0.66 g kg and a SD 12 (i.e., 0.82 g kg). Such calculations try to assess true between-subject variation rather than measurement errors....

Determining the role of omega3 fatty acids and other polyunsaturated fatty acids in weight control

The positive effects of omega-3 PUFAs were observed early on among Greenland Inuits, who, despite high fat intake, displayed low mortality from coronary heart disease (Dyerberg et al., 1975). Other epidemiological studies have reported lower prevalence of obesity, type 2 diabetes and cardiovascular diseases in populations consuming large amounts of omega-3 PUFAs from fatty fish (Mouratoff et al., 1969 Kromann and Green, 1980). Subsequent studies have demonstrated that dietary supplementation of omega-3 PUFAs exerts positive effects in several metabolic diseases including coronary heart disease, hypertension, arteriosclerosis, diabetes and inflammatory diseases (Terry et al., 2003 Din et al., 2004 Calder, 2004 Ruxton et al., 2004). The PUFAs are fatty acids containing two or more double bonds. These fatty acids are essential since they cannot be produced in the human body and must therefore be provided in the diet. There are two main types of PUFA, the omega-3 and the omega-6 fatty...

Origin and Framework of the Development of Dietary Reference Intakes

This report is the sixth in a series of publications resulting from the comprehensive effort being undertaken by the Food and Nutrition Board's (FNB) Standing Committee on the Scientific Evaluation of Dietary Reference Intakes (DRI Committee) and its panels and subcommittees. This initiative began in June 1993, when FNB organized a symposium and public hearing entitled, Should the Recommended Dietary Allowances Be Revised Shortly thereafter, to continue its collaboration with the larger nutrition community on the future of the Recommended Dietary Allowances (RDAs), FNB took two major steps (1) It prepared, published, and disseminated the concept paper, How Should the Recommended Dietary Allowances Be Revised (IOM, 1994), which invited comments regarding the proposed concept, and (2) It held several symposia at nutrition-focused professional meetings to discuss FNB's tentative plans and to receive responses to the initial concept paper. Many aspects of the conceptual framework of the...

Dietary Sources and High Intakes

Table 2 lists the riboflavin contents of some commonly consumed foods in Western countries. As is the case with most other B vitamins, the richest food sources comprise items such as offal and yeast extract, with meat and dairy products also providing quite generous amounts fruit and vegetables somewhat less, and the smallest amounts, in relation to their energy content, being present in ungerminated grains and seeds, such as nuts. There is an enormous difference in intakes and in status observed between most Western countries, where the dietary intake tends to be quite generous, and many developing countries, which depend on monotonous and ribo-flavin-poor staple foods such as polished rice. In developing countries, riboflavin deficiency tends to

Professionalization of Dieting

In the history of dieting, various groups and individuals have been responsible for handing out dieting advice. From the 1860s to the 1950s, the church and religious groups, as well as celebrity and socialites from Lord Byron to Upton Sinclair, emphasized the importance of keeping the body pure (Griffith 2004 50). In the 1960s, people shifted from following traditional diet advice of keeping the body clean to conforming to a thinness campaign (Bordo 2003 102-3). Restrictive diets became popular and, thus, the average American looked to supermodels like Twiggy for advice. Again, in the 1980s, celebrity figures and fad doctors published the bulk of dieting books and gave out dieting tips on how they were able to achieve a slim figure. Celebrities like Jane Fonda and Oprah, among others, provided their personal dieting stories for Americans to follow. Currently, the research-driven food and dieting industry has caused a shift in dietary advice, which emphasizes the expertise of medical...

Dietary Selenium Absorption and Mechanisms of Incorporation of Selenium into Selenoproteins

Figure 1 summarizes the main pathways of interconversion of selenium in mammalian tissues. Selenium appears not to be an essential element for plants, but it is normally taken up readily into their tissues and is substituted in place of sulfur, forming the seleno-amino acids selenomethionine and selenocysteine, which are then incorporated at random in place of the corresponding sulfur amino acids into plant proteins. All branches of the animal kingdom handle selenium in essentially similar ways. When ingested, plant selenium-containing proteins liberate free seleno-methionine and selenocysteine, either for incorporation at random into animal proteins or for metabolic turnover, to liberate inorganic selenide, which is the precursor of active selenium to be inserted at the active site(s) of the selenoproteins. Selenide is also supplied by the reduction of selenite and selenate that enters the diet from nonorganic sources (i.e., from the environment) or from dietary supplements of...

Selenium Distribution Status Assays and Dietary Reference Values

A summary of reference values and recommended intakes of selenium from three publications is presented in Table 2. Dietary reference values for Intake AI, Adequate Intake RDA, Recommended Dietary Sources UK Department of Health (1991) Dietary Reference Values for Food Energy and Nutrients for the United Kingdom, Report on Health and Social Subjects No. 41.

WHO FAO WHO FAO (2002) Human Vitamin and Mineral Requirements. Report of a Joint FAO WHO Expert Consultation, Bangkok, Thailand. Rome WHO FAO. More recently, selenium recommendations or reference values have been slightly lower. The US committee that set Dietary Reference Intakes in 2000 interpreted the Chinese estimate of 41 mg day needed to saturate GPx in adult men, and data from New Zealand indicating selenium intake adequacy at 38 mg day, as...

High intensity interval training HIIT for fat loss

After low intensity exercise, the magnitude of the EPOC is so small that its impact on fat loss is negligible. Somewhere between 9 and 30 extra calories are burned after exercise at an intensity of less than 60-65 of maximal heart rate. In other words, a casual stroll on the treadmill will do next to nothing to increase your metabolism. Ironically, weight training has a much higher magnitude of EPOC than aerobic training. Studies have shown increases in metabolic rate of as much as 4-7 over a 24hour period from resistance training. Yes - that means weight training does burn fat -albeit through an indirect mechanism. For someone with an expenditure of 2500 calories per day, that could add up to 100 - 175 extra calories burned after your weight training workout is over. The lesson is simple Anyone interested in losing body fat who isn't lifting weights should first take up a regimen of weight training, then - and only then -start thinking about the HIIT

Traditional Eating Habits

Traditional eating habits of Mediterranean countries, and those countries along the basin, include olives, fish, lamb, wheat, rice, chick peas and other In ancient times, sea trade brought many of the world's cultural and culinary achievements to the nations around the Mediterranean Sea. More recently, the Mediterranean diet which features low-cholesterol foods such as vegetables and fish, and includes very little meat has been recognized as one of the world's healthiest.

Obesity and Sleep Apnea

There are several correlates of sleep apnea. It is well recognized that it is more prevalent in males, although the difference is less pronounced in population-based studies than in laboratory-based studies. 20 Some studies have suggested that the prevalence of sleep apnea in women increases after menopause. Snoring also correlates with sleep apnea, increasing up to late middle age and decreasing thereafter. 20, 282, 654, 655 The other major correlate of sleep apnea is obesity 20, 653, 654, 656 in both men and women. In general, women have to be significantly more obese than men for the clinical syndrome to be apparent. 657 At present, no published epidemiologic studies have examined the relationship between race and sleep apnea. Given the high prevalence of obesity among specific populations and minorities, sleep apnea may be highly prevalent in these groups. The evidence that treatment of obesity ameliorates obstructive sleep apnea is reasonably well established. Although the...

Present Day Eating Habits

Modernization has created significant changes in food consumption patterns in the countries of the Mediterranean region. The factors affecting the traditional dietary customs of the region are economy, environment, society and culture, disasters (e.g., war, drought), the expansion of food industries, and advertising campaigns promoting certain foods (e.g., soda, candy bars). Fast-food restaurant chains are also altering traditional diets. The expansion of fast food has resulted in the population consuming processed foods such as sweets and snack foods, which were never a part of their nutritional sustenance.

Dietary recommendations and therapeutic use

As presented here, PUFAs have the potential to affect a large number of metabolic processes and, therefore, these fatty acids are beneficial in obesity and its related diseases. The most important effect of omega-3 PUFAs, and in particular EPA and DHA, is the triglyceride-lowering effect observed in humans (Connor et al., 1993). Lowering circulating triglycerides has been proven to protect against coronary heart disease and the use of fish oil or increased consumption of fish after myocardial infarction reduced reinfarc-tion and mortality (Calder, 2004). The American Heart Association have presented guidelines for dietary fish intake, proposing that patients without documented coronary heart disease should eat a variety of fish, preferably oily fish, twice a week (Kris-Etherton et al., 2002). Patients with documented coronary heart disease should consume dietary supplementation of at least 1 g EPA and DHA per day. Long-chain omega-3 PUFAs derived from fish and fish oils have...

Recommended Dietary Intake Chart

For more than 50 years, nutrition experts have produced a set of nutrient and energy standards known as the Recommended Dietary Allowances (RDA). A major revision is currently underway to replace the RDA. The revised recommendations are called Dietary Reference Intakes (DRI) and reflect the collaborative efforts of both the United States and Canada. Until 1997, the RDA were the only standards available and they will continue to serve health professionals until DRI can be established for all nutrients. For this reason, both the 1989 RDA and the 1997 DRI for selected nutrients are presented here.

Dietary Reference Intakes Recommended Intakes for Individuals

Note This table presents Recommended Dietary Allowances (RDAs) in bold type and Adequate Intakes (AIs) in ordinary type followed by an asterisk (*). RDAs and AIs may both be used as goals for individual intake. RDAs are set to meet the needs of almost all (97 to 98 ) individuals in a group. For healthy breastfed infants, the AI is the mean intake. The AI for other life-stage and gender groups is believed to cover needs of all individuals in the group, but lack of data or uncertainty in the data prevent being able to specify with confidence the percentage of individuals covered by this intake.
