The Medifast Plan

The Science Behind Medifast

Medifast is the brand recommended by over 20,000 doctors and used by over one million customers since 1980. Medifast Programs and Products were developed by a physician and have been clinically proven in numerous studies conducted by major university teaching hospitals. Additionally, third-party studies published in leading medical journals have deemed meal replacements an effective means of weight loss and weight maintenance.

Medifast Meals are nutritionally complete, low-calorie, and low-fat, providing everything your patients' bodies need to lose weight quickly and safely. Medifast Meals contain a medically designed balance of protein and carbohydrates, as well as 24 essential vitamins and minerals per serving, ensuring your patients' daily nutritional requirements are met while losing weight on the program. Unlike fad diets that restrict a specific macronutrient such as protein or carbohydrates, Medifast is nutritionally balanced, allowing your patients to maintain lean muscle as they lose weight. This helps your patients continue to burn fat as they transition and maintain their weight loss long term.

Most Medifast Meals are formulated with heart-healthy soy protein, which, according to research studies, may help reduce the risk of heart disease. Soy's naturally occurring isoflavones may also help reduce the risk of bone fractures and osteoporosis. Soy protein is a complete protein, providing all of the essential amino acids. Medifast also offers products formulated with whey protein, for customers who have an allergy to soy or prefer a non-soy product.
