The prevalence of obesity in af¯uent societies is reaching
epidemiological proportions and even if our understanding and knowledge of the causes leading to obesity are ever increasing, health professionals cannot seem to reverse this situation. Obesity is being characterized as a long term energy imbalance, that is energy intake (EI) being greater than energy expenditure (EE). Many studies have shown that nutritional and food-related non-nutritional factors in¯uence the adjustment of EI to EE. The main objective of this report is to describe the effects of some of these factors with the intent to propose strategies that would enable health professionals to further improve their inter- vention in obese individuals.
