The Medifast 5 & 1 Plan® is designed for fast, safe weight loss. Eat five of our specially formulated meals and one Lean & Green™ Meal of your own, and you can lose 2-5 pounds a week for the first two weeks and 1-2 pounds per week thereafter.
But it doesn’t end there. We’ll see you through every phase—with plans for weight loss, transition, and maintenance—to help you make those changes last.
Your next phase starts with Medifast,
the science of a healthy life.
Eat six meals a day and lose weight quickly, all while learning healthy eating habits that will remain with you long after you reach your goal.
You can expect to lose 2-5 pounds per week during the first two weeks and 1-2 pounds each week thereafter.
There’s life after weight loss, and it starts with Medifast’s Transition Plan.
Once you’ve achieved your weight loss goal, follow the 6-week transition to lifelong healthier eating.
After all your hard work, learn how to keep the weight off! Medifast offers you a common-sense approach to healthy weight maintenance.
Medifast’s Maintenance Guide teaches you how to balance your food intake based on the calories you burn.
How long you follow the plan is based on your body and how much weight you want to lose.
During Transition, you incrementally increase your daily caloric intake by reintroducing a different food group each week.
Luckily, the formula is simple!
To maintain your current healthy weight, your calories in need to equal your calories out. Otherwise, you’ll continue to lose weight—or gain weight back.
Once you’re reached Maintenance, we’ll help you calculate your daily caloric needs and build a maintenance plan based on your height, weight, age, gender, and activity level—so you stay fit for life.
Enter the Medifast 3 & 3 Plan:
In this phase, you’ll eat three meals and three “fuelings” per day. Your daily meal plan will feature lean protein and vegetables, and 3 Medifast Meal Replacements.
