The OPTIFAST^® PROGRAM

OPTIFAST is the original medical weight loss program. It has been available in the US for over thirty years, and during that time, it has been used safely by more than a million people and been the subject of over 84 different research articles.

The OPTIFAST Program is a comprehensive medical weight loss program that combines a specialized meal replacement formula diet with medical monitoring to ensure safe and effective weight loss and a behavioral change program that address all aspects of successful weight management including diet, physical activity, and lifestyle skills like stress management and creating a realistic self image.

The OPTIFAST program was developed at a teaching hospital in the US and gradually spread to other healthcare institutions here and abroad. It has been used safely and successfully for over thirty years by more than a million people. Not only was OPTIFAST the first medical weight loss program, it was also the first weight loss program of any type to publish both short- and long-term weight loss results.

The safety and effectiveness of the OPTIFAST nutritional products and the OPTIFAST medical weight loss program have been proven in over 84 research papers, published in leading science and healthcare journals.

Since its inception, the OPTIFAST Program has incorporated proven new weight loss techniques and nutritional advances while maintaining the high quality program and core strengths that have built its reputation for healthy success.
