Symptoms and Side Effects

What symptoms and side effects might I experience on the program?

*NOTE: Most of the time, our Clients report feeling energized and better than they did prior to starting a Medifast Program. If you are ill or do not feel well, see your doctor. Unless your doctor says otherwise, you should be able to continue on the Medifast 5 & 1 Plan, as most symptoms experienced are temporary.
