Medifast has been in existence since 1980 and is currently recommended by over 20,000 doctors, according to the program’s website. The diet, developed by William Vitale, a medical doctor himself, is high in protein and nutrients and low in fat, carbs, and calories.
Medifast subscribers can choose from among a number of personalized plans, including those designed specifically for men, women, teens, seniors (70+ years of age), vegetarians, and people suffering from diabetes, gout, celiac disease, or gluten sensitivity.
Participants in the basic 5 & 1 Plan eat six meals a day, five of which they purchase from Medifast, either online, at a Medifast Center, or through a registered Medifast medical doctor. These Medifast-provided meals (over 70 of them to choose from) include eggs, oatmeal, pancakes, soups, chili, stew, hot drinks, fruit drinks, iced teas, bars, puddings, shakes, and “soft serve.”
