Modifier le comportement alimentaire : mission impossibles ?

Is it possible to modify intake behaviors for body weight control purposes? Over the last 40 years, dozens of international, peer-reviewed articles have described behavior modification approaches aiming at body weight reduction. The present article first presents a historical account of behavioral methods and their results. From the early therapies exclusively addressing behaviors (excluding restrictive diets) until the recent cognitive-behavioral treatments, published studies have reported modest weight losses associated with numerous metabolic, nutritional and psychological benefits whose maintenance, beyond the treatment duration, appear reasonably good. Recent studies specifically address the conditions of long-term maintenance. The main elements of behavioral-cognitive treatments are described briefly. Finally, the particular problems associated with these approaches in the French context are underlined.
