Dietary approaches to manage body weight.
It has been established in the Canadian Community Health Survey that 23% of Canadians are obese while 36% are over weight. The fact that obesity is associated with an increased risk of developing cardiovascular disease, type 2 diabetes and other chronic diseases explains why many efforts have been put forward to develop tools that can be helpful for achieving body weight loss. Nutrition intervention is at the cornerstone of obesity treatment. In order to achieve body weight loss, energy intake must be lower than energy expenditure. This mathematical equation is rather simple and can falsely suggest that achieving long-term weight loss is simple and easy. However, many studies have demonstrated the poor long-term success of weight loss interventions. Biological as well as behavioural and environmental factors can all contribute to body weight regain after weight loss. This paper will discuss some nutritional strategies that can be helpful to induce a reduction in energy intake. Namely, the impact of reducing energy density, reducing portion size and improving the recognition of hunger and satiety signals and diet modification will be discussed.
