Clinically proven weight loss designed, used, and recommended by doctors

Medifast Meals were first created in 1980 by William Vitale, M.D. His products were sold directly to doctors, who in turn prescribed them to their patients for weight loss.

Medifast has been recommended by over 20,000 doctors and used by over one million customers—including doctors and their family members—since 1980.
