OPTIFAST® Success Stories


40 lbs*

“The OPTIFAST program helped me to reset the way I thought about food to find self-control when I did not have it before. If I could say anything to my old self, it would be just do it. It's going to be the best thing you ever did for your health.”

* OPTIFAST® patients who actively participate in a 26-week program typically lose approximately 30 pounds with weight loss-related improvements in blood glucose, blood pressure, and cholesterol levels.1-4
**Maintaining a healthy weight is associated with reduced risk of diabetes, heart disease, sleep apnea, and increased life expectancy.  These benefits are not limited or attributed to weight loss with the OPTIFAST® Program, specifically. However, no patient’s case is typical.
