Weighing the options: criteria for evaluating weight-management programs. The Committee to Develop Criteria for Evaluating the Outcomes of Approaches to Prevent and Treat Obesity.

The scientific evidence suggests strongly that obese individuals who lose even relatively small amounts of weight are likely to decrease their blood pressure, reduce abnormally high levels of blood glucose, bring blood concentrations of cholesterol and triglycerides down to more desirable levels, reduce sleep apnea, decrease their risk of osteoarthritis of the weight-bearing joints and depression, and increase self-esteem.

Very low calorie diet programs have limited long-term success that may not justify the risk of adverse effects and high costs, and longer program attendance and continued exercise are associated with improved weight maintenance.

Thirty-month evaluation of a popular very-low-calorie diet program.

Very-low-calorie diet programs can be effective in maintaining a medically significant weight loss in some patients at 30 months after program entry, and the high costs and rate of weight regain indicate the need to find a more affordable and effective strategy for weight loss and maintenance.
