Medifast is a clinically proven weight loss program that is geared toward our busy lifestyles. Medifast participants select a monthly meal plan for a fixed monthly fee. Each meal plan consists of 800-1,000 calories, creating a healthy caloric gap which causes your body to burn fat reserves. Most people lose weight quickly, as much as 20 pounds a month, significantly faster than other weight loss regimes. In addition, Medifast meal plan options include those for consumers with Type 2 diabetes, and similar weight-related illnesses. Medifast emphasizes the importance of exercise, adequate rest and an all-round healthy lifestyle to maintain weight loss and increase an individual's general well-being.
