Medifast Diet Review

Medifast was established in 1980 by Dr. William Vitale, and is essentially a meal replacement and meal delivery service for helping people lose weight. The Medifast plan menu consists of protein shakes, soups, and bars. There are over 70 meals you can choose from, and the program prides itself on its customers never having to go to the grocery store. Although the prepackaged meals can be a real convenience, they can also make social outings difficult when wanting to eat out with others. Another problem lies in the fact that the meals may not taste to your liking, causing waste and hunger.* The diet cuts out a majority of carbs, and they limit your caloric intake substantially, which can also be a major adjustment for those trying to get into the swing of losing unwanted weight.* They offer a variety of products such as bars, shakes, and even medifast pancakes.

How Does the Program Work?

Medifast’s most popular diet program is called the 4,2,1, and it covers four Medifast meals, two lean and green meals and one healthy snack.* The Medifast team says that when doing this particular program, you can lose a small amount of weight per week during the first two weeks. While on this particular program, you are only allowed to consume 800-1000 calories a day, which has some critics unsure about the drastic cut of calories and how it will benefit your health. The overall idea of the program is very smart, however the food has been noted to taste terrible to some people, which would be a bad investment in the long run. All of the meals are shipped to your front door, and you are expected to cover the shipping costs.

Sample Meal Plan:

  • Breakfast: Medifast Oatmeal
  • Mid Morning Snack: Medifast Hot Drink
  • Lunch: 7 oz. grilled shrimp, 2 cups of salad greens, ½ cup of broccoli and shredded cabbage, and 2Tbsp. of low carb dressing.
  • Mid Afternoon Snack: Medifast Fruit Drink
  • Dinner: 6 oz. grilled chicken breast, 2 cups of fresh baby spinach, ½ cup of mushrooms and tomatoes.
  • Evening: Medifast pudding made with 1 cup of skim milk.


  • Convenient healthy meals delivered to your home.
  • There are a good variety of shakes, bars, and soups from which to choose.
  • The overall plan is simple to follow.


  • The taste of the meals has been said to taste poorly.
  • Expensive meals for one person ($300.00 a month!).
  • Does not promote long-term health and weight loss.*
  • There is only a 30-day money back guarantee, which only gives your body a chance to sample for a couple of weeks.

Do Dieters Lose Weight With Medifast?

There has been mixed reviews on whether or not this program helps people lose weight for the long term. Because the caloric restrictions can go as low as 800 calories per day, it would be hard not to lose weight, no matter what program you’re using. A lot rides on your liking to the foods that are prepared for you, and whether or not you enjoy the taste. The cost is also a huge factor in people’s weight loss success and or failure, as it is not a cheap program overall to follow long term. We found some outside reviews which were very helpful to read:

Amy* said, “I tried Medifast after hearing ads on the radio. The counselors were nice enough. I carefully followed the program to the letter and had very little success after the first week (about 3 pounds). The packaged food is almost inedible. Seriously, some of the most disgusting food I’d ever put in my mouth! She went onto say that after a summer of struggling through the program for hundreds of dollars and only a few pounds lost she quit. It was a miserable experience for her overall, and she felt like it was too expensive for how bad the food tasted. She would not recommend to anyone looking to start this diet.

Robert* said, “I did lose about 2-3 pounds a week, however did gain some of it back recently, didn’t focus on long term care. Lose weight but got sick, constipation. Horrible, could only eat a few of the different items, bars, shakes. Honey pretzel sticks were the only thing I wanted to eat the rest was a chore to eat. Coaches were helpful. She explained how the program worked and what would happen… she kept me accountable and that was very helpful.” He went onto say that the changes that they made were much needed but it was very expensive for his budget

Is Medifast Easy To Follow?

The program overall has a lot of moving parts in which some people have a hard time following it. Others however see the pre-made meals and snacks as quite the convenience if they like the taste of them, that is! The food is pre-packaged so the overall quality of the food is in question as many of the items contain soy which is not known to be great for you, as well as other preservatives that do not help with your waistline. There were side effects of feeling massive hunger as the portions seemed off for some people, as well as sudden weight loss too fast which can also cause health complications. Blood sugar, and body composition can be very sensitive, so easing your body into a new diet routine with healthy food and plenty of water is key with anything.


Pre-made meals may not be for everyone, but this program does promote healthy eating and does not over promise large unrealistic numbers with your weight loss goals. It is convenient, but it does come with a price tag and is still processed, not clean eating type of food program that would not only guarantee weight loss but would also improve your overall health. The saying “you are what you eat” mean exactly that, eat healthy and clean and your body will reward you in feeling clean and healthy from inside out. Have you ever noticed how eating fresh, non-packaged foods even for a short while improves your energy levels, gives a natural glow to your skin, and even makes you feel lighter?

One month of meals for one person starts at $300.00-$400.00, and it goes up from there. It is a steep price to pay for meals when you are unfamiliar with the taste at the beginning. This factor alone makes this program unaffordable for a large amount of the general population. This program is not for everyone, but there are a mixed number of negative to positive reviews based on taste and convenience to note.*

    I’ve had great success on Medifast and I would definitely recommend the plan for those who have tried and failed with other plans as I have. The food is what it is. There are some really good meal replacements and some that aren’t that great. And there are many ways to prepare the lean and green meals so that is hard to get bored. With so many options though, you’re sure to find a few things you like. And if one follows the program, from weight loss to transition to maintenence, as well as taking responsibility for why you came to need this program (or any weight loss program) to begin with, you will find success during and after Medifast. It’s not for everyone but what is? This plan works for me where I had no success in weight watchers. At the end of the day, you get out of it what you put into it.

    Egg whites mixed with 1 cup of a green fresh vegetable steamed, twice a day, 1/2 slice of rye toast dry at noon. Four cups of egg whites with a salad for dinner using a tablespoon of white vinegar and 1/2 teaspoon of honey for dressing. Do not eat meat more than twice a week. Oatmeal in a small amount with almond milk as an alternative meal.

    $300 a month is expensive?That’s about half of what I pay now.

    Has any one else had an issue with acne break outs? Within the first week I began having breakouts, which is rare for me, even as a teenager. Did some reading and noted that soy allergies can manifest themselves as acne. Love to hear if anyone else has experienced this.

    I agree with the other comments I read above-the food is horrible(too spicy for someone with acid reflux) and the nutritional bars all contain hidden sugars to make them taste good-but could be potentially harmful to someone with diabetes 1 & 2. The minute you stray from the plan to live normal-you gain weight and the consultants do no like it when you count calories on the side-they reprimand you severely verbally. I was able to loose weight when I combined some of their products and counted calories-it was MY choice to stick with my diet-I had several check in calls from them where I was yelled at and they kept using the same prepared questions. They did not personalize it to the individual and the job they had to support the purchases of their extremely expensive foods. There are similar diet foods on the market that are half the cost and give you the same nutrition and benefits. I spent almost $250+ a month on food-in addition to normal foods which really stresses our family budget. The consults are all skinny and cannot relate to someone who is obese fighting to loose weight-they know very little about actual nutrition and current healthy updates on food only what they are told. I got tired of the cost, verbal abuse and chose to quit and loose weight on a adapted plan.
