In September 2012, Medifast's subsidiary, Jason Pharmaceuticals, paid a $3.7 million USD civil penalty for false advertising. The Federal Trade Commission and United States Department of Justice said that advertisements for the "Medifast 5 & 1 Plan" low-calorie diet told consumers they could "lose up to 2-5 pounds per week.", and that these weight-loss claims lacked a reasonable scientific basis, and were unsubstantiated. Under the settlement, any future claims made by the company must be backed by at least one human clinical study.
