"In my opinion, the OPTIFAST Program is the most effective medical treatment for significant obesity.

Its emphasis on behavior modification enables motivated patients to achieve medically significant weight loss and to keep it off for the long run. The program is supported by more than 80 clinical studies in peer-reviewed medical literature, and it has worked for my patients for over 20 years."
