Weight-Loss Plans

How Our Plans Work

Medifast was developed by a doctor to help you lose weight fast. The delicious Medifast Meals you’ll enjoy are nutritionally balanced, packed with protein and contain 24 vitamins and minerals. You’ll eat every few hours to help keep hunger away as your body burns fat and you lose weight.

Our easy-to-follow plans: 3 simple parts.

Medifast Meals

Each Medifast Meal is fortified with the essential vitamins and minerals you need for healthy weight loss.

Our nutritionally balanced meals are all based on a similar design, so they are easily interchangeable and you’re assured of getting great nutrition everyday.

Choose from over 65 delicious options like bars, shakes, breakfast foods, soups, pastas, desserts, and more!

Lean & Green Meals

A lean and green meal includes five to seven ounces of lean protein, three servings of vegetables, and up to two servings of healthy fats, depending on your lean protein choices.

Make your own meals using great-tasting Medifast recipes, which can be found on our blog or in our cookbook, or if you are too busy or don’t like to cook, enjoy one of our Medifast Flavors of Home® lean and green meals.
