Fifty Years of Behavioral/Lifestyle Interventions for Overweight and Obesity: Where Have We Been and Where Are We Going?

Donald A. Williamson
Objective This paper reviews the literature pertaining to the structure and content of intensive lifestyle interventions (ILIs) for overweight/obesity since Richard Stuart described this new treatment approach in 1967. A consensus opinion has formed that behavioral/lifestyle treatment of overweight and obesity should be viewed as a mainstream intervention for the treatment and prevention of type 2 diabetes and medical complications associated with obesity. Methods The development of modern ILIs and demonstration of their efficacy are compared by structure, content, and efficacy of four major randomized controlled trials: Diabetes Prevention Program (DPP), Look AHEAD, POUNDS Lost, and CALERIE. Results The results of these studies indicated that modification of lifestyle behaviors related to nutrition and physical activity can yield weight loss and prevention or improvement of a variety of medical conditions associated with obesity in a variety of subpopulations. Conclusions Recommendations for the structure and length of behavioral/lifestyle interventions have been recently adopted by agencies and institutions that approve reimbursement for medical services. These recommendations represent a giant step in the effort to recognize ILIs as a mainstream approach for the treatment of obesity and comorbid medical conditions. Nevertheless, they do not adequately represent advances made since the publication of the DPP results.
