08 Mar 2018 --- Although different popular diets can help some people achieve modest weight loss with potential improvement in health risks, maintaining long-term weight loss remains challenging, and individuals with obesity should expect to regain weight when they stop treatment, according to a Scientific Statement by the Endocrine Society. The statement's authors examined the latest scientific evidence on a variety of diets, commercial diet plans such as Weight Watchers, exercise, obesity medications and types of bariatric surgery. Based on a review of more than 400 studies and peer-reviewed articles on obesity, the experts found all of the weight loss interventions had a high degree of variability when it came to effectiveness.
