The Results Are In

Study 1

REFERENCE: Crowell, M.D. & Cheskin L.J, The Johns Hopkins University School of Medicine. Multicenter Evaluation of Health Benefits and Weight Loss on the Medifast Weight Management Program.

PURPOSE: To retrospectively evaluate the efficacy of a medically supervised, protein-supplemented modified fasting program (Medifast) for weight reduction and to evaluate the impact of weight reduction on coexisting health problems.

RESULTS: The results of the study concluded that medically-supervised, protein-sparing modified fasts offer a safe and effective means of weight reduction and are accompanied by significant improvements in coexisting health problems. Of samples taken, males lost an average of 67 lbs and females lost an average of 47 lbs during fasting. The study found significant reductions in systolic and diastolic blood pressure, total cholesterol and triglycerides, as well as the normalizing of blood pressure and hypertensive patients.


Additional Information
Study 2

PURPOSE: To evaluate the efficacy of the standard ADA (American Diabetic Association) self-selected diet (SD) vs. a portion controlled diabetic food diet (PCD) in obese patients with NIDDM. The study also aims to evaluate not only the metabolic effects in the long term, but also compliance and any consequent medication changes in patients of the two weight loss regimens. (16-34 weeks of active weight loss, 52 weeks of maintenance) The meal replacements (Medifast) used in this study are soy-based products (bars, shakes, soups) that are considerably lower in sugar than their non-diabetic counterparts and other popular diet products on the market.

Study 3

PURPOSE: The study examined whether women on a weight loss program who are carriers of a genetic variant (Trp64Arg) lose less visceral fat than women who do not have this gene. Participants entered a medically supervised weight loss program aimed at reducing body weight to less than 120% of ideal value. Food was self selected with dietitian supervision, with or without the inclusion of the TakeShape, a Medifast brand modified fasting supplement.
