Weight gain and obesity develop when the energy intake from food and drink exceeds energy expenditure from physical activity and other metabolic processes. It is often assumed that the prevention of weight gain should focus solely on attempting to alter these behaviors within individuals and communities. However, research has consistently shown that numerous and diverse factors, including environmental and social factors, influence the behaviors that lead to excessive weight gain. Addressing aspects of the obesogenic (obesity-promoting) environment, as well as individuals' eating and physical activity patterns, is considered to be critical to the success of any obesity prevention program.
The 2003 WHO report on diet, nutrition, and the prevention of chronic disease undertook a detailed review of the literature and identified a range of key factors that either increase or decrease the risk of weight gain and the development of obesity (Table 2). These factors were rated on the quality of evidence available to support their contributory role. This analysis serves as a very useful guide as to the focus of weight gain prevention initiatives.
