OPTIFAST® Liquid Diet

OPTIFAST® is a high-quality, nutritionally balanced, calorie-controlled liquid diet.

It is a more rapid, yet medically safe way of losing weight that gives a sense of accomplishment without compromising long-term weight loss. In addition to being effective, most of our participants agree that the removal of food has allowed them to more fully understand and change their eating patterns for the better.

OPTIFAST is often a treatment that works in conjunction with our Weight Loss Education programs, both of which are aspects of our Comprehensive Weight Management Center.

The OPTIFAST program is a clinically proven weight loss program with documented outcomes in more than 80 studies. Research has shown that the average weight loss in a full formula OPTIFAST program is 52 pounds. Participants have also seen an average of:

  • A 15 percent decrease in cholesterol
  • A 29 percent decrease in blood sugar
  • A 10 percent decrease in blood pressure
