People Who Viewed Medifast Also Viewed Trim Down Club.

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.

protein shakeHow 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

constipationIs 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?

healthy skinOne 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 did Medifast, lost 17 pounds, got extremely ill (not realizing it at the time). My liver counts, insulin, and glucose counts were so messed up. And, even tho I am an avid exerciser and not heavy – I gained every single pound back. Also, the food takes horrible. Would not recommend.

  • Sarah Polansky

    I was on Medifast for 7 months and lost 60 pounds. I have tried every kind of diet since I’m 12 years old. I am 61 years old now! So that’s a lot of dieting history.
    I have had 3 operations to lose weight. I was in the clinical trials for the lap band. I lost 110 pounds with that surgery. But the band slipped and I had to have emergency surgery to have it removed. I gained back 90 out of the 110 pounds that I had lost. Next, I had the gastric by pass surgery. I only lost 40 pounds with that surgery. So I was still about 50 pounds over what I was when I lost the weight with the lap band.
    My friend was very successful with the Medifast diet, so I figured I would give it a try. My coach was very helpful. I didn’t like all the foods. But, I learned which ones I liked, and stuck with those. I changed a few things in my life that I hope I will stay with. I stopped drinking diet coke. I was a huge diet coke drinker. My coach told me that it’s hindering my weight loss and I must stop drinking any diet coke. And I started drinking water – 8 cups a day! I hate drinking water! I forced myself to do it! And I got used to it. Can’t say that I love drinking water, but I am able to do it. I also started eating every 2 1/2 – 3 hours. My coach explained to me that this causes your metabolism to work efficiently all day. The way I was eating before – eating in the morning and then not eating all day and then eating all night, was the worst thing to do. My metabolism was in slow motion from not having any food all day.
    I had a very hard time the first 10 days of the program. I literally felt like a drug addict in withdrawal – probably withdrawing from the diet coke, white flour and sugar. After 10 days, my cravings and my discomfort and feeling sick disappeared and I really did not find the program hard at all.
    I am now on my own maintenance. I did the Medifast maintenance for the first 2 months after I lost the weight and now I am doing my own thing.
    I am basically eating 3 meals a day, 3 snacks in between the meals ( not Medifast products – I buy any snack below 110 calories – granola bars, baked chips, whole wheat pretzels) and I eat 2 slices of whole wheat bread a day, a fruit, and a yogurt and also 10 almonds a day. If I want to cheat – I’ll also eat a light microwave popcorn – which is 100 calories. I find this is alot of food. I am not hungry and I am basically eating all day.
    The thing that I like is that I feel if I ever do gain back a couple of pounds ( I weigh myself once a week religiously), I can always go back on the Medifast plan for a week or 2.
    The diet really worked for me. I do recommend it. But, diets are a very personal thing and this plan is not for everyone. It is a little expensive. But, if you think that basically, it’s your food for the day – it’s not really that much.
    If you figure out all the money you spend on the junk that you eat, this does not come out that much more!
    Good Luck!

    I have never been successful with any diet OTHER THAN MEDIFAST. I gained 80+ pounds with both babies and lost it each time using the Medifast program. Now, 24 years later, I’ve found that the pounds have slowly found their way back on to my body simply because I’m getting older and I not as hard on myself in terms of diet. So, in an effort to get back on track, I tried several different diets: Juicing, paleo, Atkins, organic plant based diet, etc etc etc….Didn’t lose any weight and, in several instances, I gained weight! So, I came back to old faithful and MAN AM I GLAD I DID!
    I think the difference for me is that I DO NOT THINK OF THE POWDERS AS FOOD. They are not soups, oatmeal, pancakes or mac & cheese! They are a low calorie fasting mechanism given names that are pleasant and that we understand. I do not expect to enjoy any of them….the meals do something MUCH MORE IMPORTANT…they supply my body with the perfect balance of nutrition in a 100 calorie pack so that I do not feel sluggish, headachy, tired, or weak. I have energy and I can concentrate at work. Instead of the ‘lean green’ meals, I opt to add about a cup of steamed veggies to some of the meals to add bulk. I use zucchini, brussel sprouts, mushrooms, spinach and sweet onion. Then, top with a sprinkle of garlic salt and I can eat it. It’s not great but, when I’m finished, I can actually feel my body wind back up, ready to go again!
    THE KEY IS that I don’t have to make any decisions about WHAT I can eat or HOW MUCH I can eat. I simply go to the boxes and pick one. NO THINKING OUTSIDE OF THE BOX 🙂

    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.

    • Nancy Molle

      That is not living.

  • Capt. Chris Pike

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

  • Alexandra Mouzas

    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.

  • Sherry J. Lewis

    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.

      Has anyone bottom sick from the soup products. I was sick for two days something was changed in the formula

      • Nancy Molle

        they are horrible. I used to put chicken bouillon in them. I gained most of my weight back. I had to eat it for three years just to maintain. You can never stop or it will come back. What a waste of money.
