Program Overview
Medifast is a medicallybacked weightloss system that combines portioncontrolled, nutritionally complete meals with personalized coaching. The core idea is simple: replace highcalorie, lownutrient foods with balanced, lowcalorie options while learning habits that keep weight off for life.
Founded in 1980, Medifast has helped millions of people lose weight and keep it off. It is a prescriptiononly program in many countries, meaning a healthcare professional reviews your health status before you begin.
How It Works
- Consultation. A certified health coach (or a medical professional) assesses your goals, medical history, and lifestyle.
- Personalized Plan. Based on the assessment, a daily calorie target is setusually 8001500kcal for rapid weight loss, followed by a maintenance phase.
- Meal Replacement Phase. For the first 24 weeks you eat 56 Medifast shakes, bars, or soups plus one lowcalorie vegetable snack.
- Transition Phase. Gradually add whole foods while still counting Medifast meals to keep you within the calorie goal.
- Maintenance & Lifestyle. Once goal weight is reached, you shift to a flexible plan that mixes Medifast products with regular meals, emphasizing portion control and activity.
