The OPTIFAST Program offers new hope to the obese. It is a medically based obesity treatment program that helps obese patients lose weight safely and maintain their weight loss. Developed by Sandoz Nutrition (now Nestlé HealthCare Nutrition), the OPTIFAST Program is based on the belief that a problem as complex as obesity requires a complex solution—one that deals effectively with the physical, social, and emotional aspects of being overweight. OPTIFAST has evolved to be a multidisciplinary approach to obesity treatment that combines a high quality, calorie controlled full meal replacement diet with behavior modification, nutrition education, exercise, psychological support, and medical monitoring of the patient’s conditions.


The OPTIFAST products are manufactured by Nestlé HealthCare Nutrition. This includes a series of nutritional products useful in the treatment of obesity. Foremost among them is the OPTIFAST 800 full meal replacement products which can be used by patients in a complete meal replacement program. The OPTIFAST Formula contains balanced nutrition, including high quality protein, carbohydrates, minerals, and vitamins. It contains no amphetamines, laxatives, or water pills, and is available only through physicians who have received training in the OPTIFAST Program.
