At the heart of the OPTIFAST Program is a portion-controlled, calorically precise, nutritionally complete diet that takes the guesswork out of eating. The benefits of OPTIFAST shakes, soups and bars include:

• High-quality, complete nutrition
• Pre-portioned and calorie-controlled servings
• Stimuli narrowing
• Quick and simple preparation
• Freedom from having to make food choices

During the Active Weight Loss phase, patients consume only the OPTIFAST meal replacements. Hunger typically goes away after the first week. Many patients report increased energy, attributed to more stable blood sugar levels, balanced diet, decreased weight, and increased activity level.

The active weight loss phase is followed by a 4-6 week transition period during which participants gradually add self-prepared foods back to their diets. Participants move to a long-term weight management program rich in fruits and vegetables, grains and low-fat proteins. During the program they will have learned techniques to include small amounts of their favorite foods into their new healthy lifestyle.
