Medical Monitoring

Do Medifast users require medical supervision while on the program?

You should consult with your physician prior to beginning (and throughout the course of) any weight-loss program. We strongly recommend you talk to your physician prior to starting, and throughout the course of, your weight-loss program if you:

  • are over the age of 70
  • are under the age of 18
  • have diabetes, hypertension, or any other serious medical condition
  • are taking medications, especially for diabetes
Are there any special guidelines for Medifast customers age 65 and older?

If you are 65 years of age or older, this program should be done with your physician's supervision. Your physician may recommend that you use a higher calorie meal plan than the 5 & 1 Plan (such as the 1,100-1,500 calorie meal plans found in the Medifast for Seniors Guide) based on your individual needs. Dosages of medications may need to be adjusted, and labs and vital signs may need to be monitored. For more information, please refer to the Medifast Senior Guide (PDF).
