Tools for Success: FAQs

How does Medifast work?

Medifast plans for weight loss and weight management were developed to be combinations of our doctor-developed Medifast® Meals and healthy Lean & Green™ Meals. Your Medifast Authorized Provider will walk you through the plan that best suits your health needs and provide individualized care and support, to help you achieve long-term success with weight management.

Is Medifast safe?

Yes. The Medifast brand has been recommended by over 20,000 doctors since 1980. Clinical studies conducted by researchers from the Johns Hopkins Bloomberg School of Public Health, as well as other teaching universities and institutions, have shown Medifast to be both effective and safe.

If I have diabetes, can I still lose weight with Medifast?

Yes! Medifast is safe for individuals with type 1 or type 2 diabetes. Medifast uses carbohydrate-controlled plans, and this helps you manage your blood sugar levels while you lose weight. Follow your health care provider’s recommendationsfor your specific needs, and if you have any other medical conditions, he or she will recommend the Medifast plan that is most appropriate.

Is Medifast a liquid diet?

Absolutely not.While we started our product line with delicious shakes, they are just a small part of more than 80 different Medifast Meals you can choose as part of your plan.  And at least once a day, you get to enjoy a Lean & Green™ Meal that consists of lean protein (such as chicken, fish, tofu, and lean beef) and non-starchy vegetables (such as salad greens, tomatoes, broccoli, mushrooms, and many more).

How long does it take?

Your weight-loss phase will be based on how much weight you want to lose and the recommendations of your health care provider. After weight loss, our Medifast plan supports you through transition and weight maintenance, to help ensure that you maintain your success.

How do I pay?

You may purchase some meals and get started right in your health care provider’s office. Check with your individual provider about the procedure. Once you've started the plan, you can visit your provider’s website to purchase your Medifast Meals, which are conveniently shipped right to your door.
