Does Medifast work?

Customer reviews suggest Medifast plan is easy to follow and has quick results. Medifast is a nutrition and weight loss company that prides itself on supporting any dietary restrictions and health considerations. The program works because the meal plans decrease your calorie and sugar intake, which causes the body to lose weight.

Medifast meal kits include breakfast, lunch, dinner and snack options, plus a Healthy Living Workbook and Medifast blender bottle for meal replacement shakes. Medifast also provides support to meet your dietary restrictions as well as health considerations. Daily exercise is required as part of the program.

Because Medifast was started by a doctor, it has been a popular referral by doctors for patients looking to lose weight. (Medifast claims the support of over 20,000 doctors.) The program offers two diet choices and a maintenance plan once weight goals are met.

Does Nutrisystem work?

Nutrisystem weight loss programs are glycemic index-based diets made up of good food choices and correct portion sizes. Customer reviews suggest it’s easy for the average person to follow a Nutrisystem weight loss plan, and the plan is designed in such a way that makes maintaining your weight loss easy too. After you reach your goal, you’ll start to slowly phase out Nutrisystem meals for your own.

During the program, participants receive online support through consultations and forums. Home delivered meals make up the simple 28-day program. The program also supports healthy living through diet and exercise. Vegetarian plans are available, as well as specialized programs for senior dieters and those with diabetes. Daily exercise is also part of Nutrisystem weight loss plans.

Bottom line: Medifast or Nutrisystem?

Both Medifast and Nutrisystem provide prepared meals and diet plans, but Medifast reviews score slightly higher in taste comparisons over Nutrisystem. Overall, Medifast offers more options for those with medical needs and dietary restrictions.
