Clinical Trial Summary

This research is to develop a weight loss and weight maintenance program through dietary modifications for adults with obesity. Although scientific studies have shown the feasibility of rapid and safe dietary weight loss and subsequent weight maintenance, no efficacious dietary weight management program is widely available, and thus bariatric surgery remains the most reliable approach for weight loss/management. Safe and effective dietary weight loss and subsequent weight maintenance require flexible, individualized advice by an experienced dietitian/nutritionist.
