General


What is Medifast?
Medifast is a portion-controlled, nutritionally balanced, low-fat, and clinically proven program that helps people lose weight faster and more effectively than traditional diet plans. Medifast Meals come in individual packets that you mix with water and microwave or refrigerate, and are available in a wide variety of foods and flavors, including shakes, soups, stew, chili, oatmeal, scrambled eggs, fruit drinks, iced teas, hot beverages, bars, and puddings. Quick and easy to prepare, they offer a healthy fast food alternative to a busy lifestyle!
How does Medifast work?
The clinically proven results of Medifast are based on the use of a structured meal plan featuring Medifast Meals, which are nutritionally designed with a proven combination of protein and carbohydrate, allowing you to successfully lose weight while minimizing loss of muscle. The Jump Start Plan, our standard plan for weight loss, is medically designed to create a calorie deficit, allowing your body to burn fat for energy.
What is the average weight loss amount per week?

Clinical studies indicate that most people lose an average of up to 2-5 pounds per week with Medifast. The scale isn’t the only test, so check other indicators such as your waistline measurement and how well your clothes are fitting you. Individual results may vary, and are dependant upon various factors such as your starting weight, targeted weight-loss goal, level of exercise, presence of medical conditions, use of medications, accuracy with diet compliance, etc.
Has the use of Medifast been researched?
Yes! Since 1980, Medifast has been recommended by over 20,000 doctors. Clinical studies by researchers from Johns Hopkins Bloomberg School of Public Health, as well as other major teaching universities and institutions, have shown the plan to be both effective and medically safe.
Is Medifast safe?
Medifast has been clinically proven through a number of controlled studies. Since 1980, more than 20,000 doctors nationwide have recommended Medifast Programs to their patients and more than one million customers have safely used Medifast.
Does it contain harmful herbs or additives?
No. Medifast does NOT contain any added herbal stimulants, ephedrine, or other ingredients that might be harmful to your body.

Please note that Medifast’s Health Management Shakes (Plus for Women’s Health, Plus for Joint Health, and Plus for Coronary Health)do contain some added herbal/nutrient components such as black cohosh, chaste tree berry, glucosamine, chondroitin, and Pycnogenol®. You should consult with your physician before making the choice to use Health Management Shakes, especially if you are taking medications, have a medical diagnosis, or have specific concerns about the use of an item.

Our Essential 1: Calorie Burn product line contains an added stimulant in the form of caffeine. Each Essential 1: Calorie Burn item contains 100 mg of caffeine and 90 mg of EGCG, a potent antioxidant found in green tea. This amount of caffeine is equal to one cup (8 ounces) of brewed coffee. Using Essential 1: Calorie Burn products is a lifestyle choice, so if you would rather not consume EGCG and additional caffeine, you may choose other Medifast Meals.

Has Medifast been affected by the recent peanut recall (January 2009)?
No. There is no indication that any Medifast products are impacted by the peanut recall of January 2009. Medifast has been in contact with our ingredient suppliers to ensure the safety of our products and we have verified that Medifast does not purchase any ingredients from the supplier in question. Again, we have no reason to believe that any Medifast products containing peanuts have been affected.
