Save time and energy by never having to grocery shop, count calories or cook your meals again. Medifast meal delivery service will send high protein meals directly to your home. By controlling portions, nutrients and calories, Medifast users can expect to lose 2-5 pounds per week for the first two weeks on the Medifast 5 & 1 Plan and 1-2 pounds per week thereafter.

The Medifast Plan menu consists of shakes, bars, soups, and other sides you can pair up to create your diet or the day. Medifast offers 70 meal choices to satisfy different palates and dietary requirements. Kosher, low glycemic, lactose-free and vegetarian diets are all supported by the Medifast plan.

Medifast's success has been proven in multiple clinical studies, the Medifast website offers dozens of real-life testimonials, and its products and programs have been recommended by more than 20,000 doctors since 1980.

A John Hopkins study found the Medifast plan helps dieters quickly and safely lose weight by decreasing the amount of calories they consume each day. The study also found that participants with type 2 diabetes lost 2 times the weight of individuals following the American Diabetes Association's dietary recommendations. Medifast also shows positive results in participants with other illnesses, like hypertension and high cholesterol.

All of the Medifast products are available online, but Medifast does offer some physical centers throughout the country, in Alabama, Arizona, California, Florida, Georgia, Maryland, Minnesota, Pennsylvania, Texas and Virginia.

A sampling of feedback and experiences shared by our community.

I am a 48 year old male with a fairly unactive lifestyle. On May 16, 2011 I started the Medifast diet following the 5/1 plan. My starting weight was 325 lbs. I am 11-1/2 weeks into the diet and have lost 58 lbs.

I come from a family of excellent cooks. Are the food offerings gourmet quality? No. However, they aren't, in general, as horrible as people say. Sure, there's a few clunkers out there but, for the most part, there are so many varieties that you should be able to find your way through. - Greg 8/5/11

I am 49 yrs old...5"5" and I started my program Aug 8th 2010 at 172 lbs I lost 45 lbs in 14 weeks! It's easy and the results are rapid. The first week I lost 8.5 lbs and the first month 17.5 lbs and then I averaged about 2.5 lbs a week. I have been reading lots' of discouraging people on here in regards to the food. Yes, there are some of the meals that you will not care for. But, you will figure out your likes and dislikes right away. Just don't eat more then one pkg out of each box for any returns.For me personally ..I love the bars and like the rice cakes, pretzels and puffs vanilla and mocha shakes yum! - Lorrie 8/4/11

I started medifast around October 2010. I went from 165lbs to about 142lbs in 3 months. I was very pleased. Unfortunately once I became comfortable being able to fit in my own clothes again I stopped the program. I did not start the maintenance program. My own fault. I ended up gaining my weight back and have started weight watchers and it's been successful so far. So depending on wether or not I would of stayed on the program I would have a better review. So it does work, and I do like it. But it was not for me and the food gets old quick! If you keep to it right, and do not cheat! I would cheat just for one day with some medifast and maybe a real meal with the family and I would be gaining a pound.. Just keep to it. - Alyssa 7/4/11

This diet works without a doubt as long as you can stick thru it. It is VERY difficult the first few days but once you make it thru week 1 the cravings pretty much go away. The food will also begin to taste better, however its best to try everything because not everyone like everything. I personally just do the shakes and brownies sometimes the scrambled eggs. They also have a great community site for advice and support and you can get great ways to doctor it up the meals too. The weight definitely comes off quickly and you see results weekly on the scale on with a measuring tape which is great motivation. Of course it has its downside like every diet the weight can come back quickly and more, but only if you don't go into the transition stage and gradual reintroduce foods back into your diet and maintain a healthy balanced diet. - Izzy 5/17/11


The Medifast diet consists of five prepared meals and one "Lean and Green Meal." (L&GM) known as the Medifast 5 & 1 plan. Your L&GM will consist of a lean protein (a seven-ounce serving of chicken, turkey or fish, or a five ounce serving of beef, pork or lamb) with a tablespoon's worth of condiment like ranch dressing, ketchup or mustard. You will also choose your side dish, which can include a salad, or raw or cooked vegetables. You will always eat at least three servings of vegetables in your L&GM.

The Medifast program encourages you to keep your metabolism high and avoid hunger by eating every three hours. It also recommends that you stay hydrated by drinking your choice of calorie-free beverage, preferably water, consuming at least 64 ounces each day. While your Lean and Green Meal and beverages are up to you, the rest of your meals will be chosen from the dozens of low-calorie, high nutritient meal-replacement items that Medifast delivers directly to you. With options like puddings, oatmeal, shakes, and scrambled eggs, it's hard to get bored.

At the beginning of the program, you will remove high carbohydrate vegetables from your diet like corn and carrots, to jump start your weight loss. You'll slowly introduce these items back into your diet over time and they can be a part of your diet in the maintenance phase, if you wish.

While on the Medifast program you don’t have to worry about counting anything; calories, grams of fat and carbs are all controlled and you can expect to lose between two and five pound per week. The Medifast meals are made with 24 different vitamins and minerals to keep you full and satisfy your nutritional needs.

A typical day of eating on the Medifast program looks like:

  • Breakfast – Spiced Pancakes with Sugar-Free Syrup
  • Snack – Chocolate Crunch Bar
  • Lunch – Chicken & Wild Rice Soup
  • Snack – Cinnamon Pretzel Sticks
  • Dinner – Baked Tilapia Fillet; Sautéed Sugar Snap Peas with Mushrooms, Carrots
  • Dessert – Coffee Soft Serve

The Medifast website offers an exercise guideline document, but there is specific workout program. Medifast recommends getting daily exercise, but your intensity, mode and duration are left completely up to you. They suggest running, jogging, swimming, dancing or walking, but with such a low calorie, structured program, getting your daily 30 minutes reccommended for health should be enough for you to successfully drop weight.

Medifast recommends waiting two to three weeks before introducing exercise if you do not already exercise regularly. You should also consult your physician if new to exercise. Start slow, and gradually increase you time and intensity as you feel things become easier. If you have been exercising consistently prior to starting Medifast, it is recommended that you reduce your intensity and duration of exercise for the first couple of weeks so your body can adjust to your lower calorie levels, and do no more than 45 minutes of vigorous exercise each day during this time period.

Medifast suggests, as do we, that you find something that you enjoy for your workouts so you are more likely to stick to them. The gym isn't your only option. You can take up jogging outside, dance classes, swimming, or biking to get in some exercise while finding a new activity you enjoy.

I started on 4/2/16 . To date I have lost 32 lbs. It is a simple, effective and healthy way to lose weight.. My blood pressure and blood sugar are at normal levels, and most importantly both my doctor and I are very happy with my results.

It worked for me. The food isn't great or ok but it's edible. Luckily if you have time it's somewhat easy to go off plan while staying on plan when you have an AMAZING garden, however with some family hardships I lost my way but am now back on board. Also for the one with a type 1 daughter she should be monitoring her disease and be seeing an Endo it's not Medifasts job, also just because you are going somewhat low carb doesn't' mean you can stop insulin intake for example my sons ratio is 1 for every 15 carbs plus 13 lantus a night regardless of what he eats. Personally I would never recommend a Keto diet to a type 1 because when testing Keytones how would you tell if you were in DKA or just ketosis. To me that wouldn't be worth the risk.

I've tried Medifast, and can confirm that it works! Thanks for the great review.

I was on medifast for 6 months. What I liked was the 1:1 consultation and support. I did lose 30 pounds despite struggling to engage fully in the system. However, I found most of the food inedible and got to the point where I was skipping meal to avoid eating much of the food. This does not work in this system as it effects metabolism. The bars are all pretty good. Some of the shakes are ok. The cereal is alright and beyond that I really struggled to eat anything and I am NOT a picky eater.

The idea behind medifast is great. Problem is - the food is MARGINAL (at best) and downright DISGUSTING (in some cases). Additionally, the idea is to DETOX from sugar, but you fill your body full of chemicals and preservatives-and they are NOT toxic? That is laughable! So - if weight loss is the ONLY goal, it is good. If you want HEALTH to go along with it, find a different program!

In just over 6 months, I have lost 73.6 lbs. I am off blood pressure and type II diabetes meds. My doctor is amazed at the improvement in my blood tests and calls me his 'poster child'. This program has changed my life.

I have failed so many times over the past 20 years. I needed something structured, easy, convenient....and to build up my battered confidence that I even COULD lose weight, I needed to see results. This is working for me. The food is OK, I'm not hungry, I have bags of energy and I am down 20 lbs in less than 6 weeks.

My daughter type 1 diabetic tried Medifast and they did not monitor her disease. She lost 17 lbs. 1st few months but had terrible high blood sugars. Now they have taken her off her weight loss program due to contract of 16 weeks and she has gain all and more back. Very discouraging for her and that they did not make an initiative to help with her to lose the way she had planned.

Bad after-taste with MOST MEALS - tried for two weeks now, will not re-order!!

posted Feb 3rd, 2015 3:34 am



Food has way too much artificial sweetener. Flavor of fake sugar was overwhelming
I was unable to make it through one day.
Their return policy is awful. I lost a lot of money on a diet I did for one day.

I was 285lbs. Black male with history of hypertenison. So, just a step from type II diabetes and or stroke. I went on medifast diet first of nov, by the time for Easter, I was 221. All this and i wasn't strick. I like the foods for the most part. Some items "no", most yes!

Worst diet ever. Tastes terrible and I was always hungry. Literally threw it away. Waste of money.

The food is basically in edible. No one in my office can eat more than one bite of anything I have had them try. I was so determined to do this diet I opened all the boxes and put the food in my work cabinet and home. Little did I know I wouldn't be able to eat it. This diet food is terrible! Would never recommend it and totally wasted my money. Nutrients email is much better. I can't even give this stuff away. People eat it and then have to rinse their mouth out. Total rip-off. Another lesson learned.

Medifast does work if you strictly adhere to its plan. I was on Medifast 5&1 for 3 months, and dropped down to the number I aimed for on the scale, and it did help me tame my sweet tooth and carb cravings. I did gain the weight back due to personal stress after getting off the plan. I found the foods not too bad and had no complaints about them.

posted Nov 29th, 2014 4:15 am



I love this program. I have lost 88 pounds in 27 weeks. I am seven pounds from goal. As a busy mom of four and middle school teacher, I love the convenience of the meals. There are only a few meals that I don't like; otherwise, the food is very satisfying.

I ordered food, and they lost my order and shipment and will not give me my money back until it is tracked down. They blame it on UPS and UPS has no answer either.. If you are open to have your money stolen then this is the business for you!!!

Horrible customer service and shoddy business. Stealing money is their only objective. Stay away

My first time trying medifast, I lost 18 pound the first two weeks. I only didi the program for a month and lost a total of 23 pounds without exercising. Since then I've had a baby and will be doing the program again. This time for 4 months. I'm hoping to lose about 60 pounds this time. Best of luck!!!

I am on week four and finding it very successful. I especially enjoy the counseling support and would recommend this as part of the plan. All but one of the food items I have tried have been pretty tasty.
