The Plan is designed to help you lose a significant amount of weight while keeping you full and satisfied.

We're Backed by Science

Medifast Meals are doctor-designed nutrition. They are low glycemic, low in calories, scientifically formulated with the best proportion of macronutrients (carbs, protein, and fat) and fortified with the optimal vitamins and minerals. And each meal has a similar nutritional footprint, so you can swap them and still be thoroughly nourished!

Numerous studies at major university teaching hospitals have proven Medifast Meals to be safe and effective. Studies published in major medical journals have proven meal replacements to be an effective method of weight loss and weight maintenance.
