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 even has specific plans for the unique needs of women, men and diabetics.

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. You can choose to go to a center, but you can complete the program online just as easily.

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.

Lucy Mcgee, did you do your research? You are only supposed to eat 5 medifast meals (plus a lean protein and salad) per day. This comes out to 800-1000 calories per day, but the amino acids and vitamins in the food keep your body from going into starvation mode. Where did you get $50 per day and 2000 calories from?

It cost me about $12 a day, and being hypothyroid, nothing has let me lose faster than Medifast. Not weight watchers, atkins or south beach.

This food is very expensive and it is nothing special. It costs about $2.50 per hundred calories pretty much across the spectrum. So for an average male wanting to lose wight with a 2000 Kcal diet, the cost would be $50.00 per day.

One can use someone like Jamie Oliver's cookbook and create much healthier meals for less money which taste much better.

But they do sell a dream. Uggh.

I've been using the Medifast products with the Take Shape For Life program for 4 months now. I lost 25 lbs in 7 weeks and am now coaching others in the program, which is free to clients! Medifast compensates us, so you get a personal coach to guide you through it! How awesome is that?! That was the key to my own personal success. I am now on my way to Optimal Health! Contact me if you want a coach to guide you in this amazing program.

I had done medifast years before and decided to try it again after having a baby to lose the baby weight. I am in good health and do not have any issues.
Shortly after ordering my supply I started to notice whenever I ate the food I would get extremely sick. I was throwing up, so dizzy I can't stand and this would last for many hours. At one point it was so bad I contemplated calling 9-1-1 to take me to emergency room. I really couldn't connect the two and just thought it was a coincidence. So I waited weeks and then try again and it would make me sick again. I called Medifast to tell them what happened and asked to return my food they said I couldn't return it because it was past 30 days. Here's what I have to say:
#1: They obviously know there food makes people sick and this is not an isolated incident. Hence, why they refused to stand by their product.
#2: There claims that this diet is healthy. If you are doing this diet you know that it is not healthy to eat a 700 calorie diet. But that still doesn't mean that it's okay to make people sick.
#3: I've been researching this online and the symptoms I had are very common, there are plenty of people posting the same thing.

I started the plan in May 2012 and stayed consistent for 3 weeks. I'm 6'1 and my beginning weight was 226. Why three weeks? Like many, I was suspicious and leery. I've never had trouble with weight (I played college basketball), but over the years with inactivity, kids, and a rigorous work schedule, I gained a bit. A little more information for you about my beginning figures, my suit jacket size 46L, pants 39W...yikes! Okay did the plan for 3 weeks and dropped 15lbs to 211. Great feat, but I decided to stop with the plan because I quickly learned how to eat and manage my meals. Today, I weigh 180lbs and have done NO exercise and haven't been maniacal about depriving myself of good food. I simply made better choices: eliminating sodas, fried foods, pastas/rice/bread, cheese and most dairy, and
many high sugar items. Don't get me wrong, I've had some cookies, donuts, and other sugar goods here-n-there, but I've been consistent.I really watch the carbs...I use an app called "Lose It". It really helps me manage my daily intake. Just so you know, I'm wearing a 41L sportcoat and 34W pants. More importantly, I feel fantastic.

In parting, there's no way Medifast can be maintained as your complete lifestyle food option. It should strictly be used to kickstart weight loss efforts and as an educational tool...teaching you what to eat, how to eat, and how different foods affect your body.

Take my comments for what you will, but it does work and can be maintained. I'm living proof and I couldn't be more thankful to the person that introduced me to the program.

I have lost nearly 60 pounds and have been maintaining my weight at a little above my target. The last few pounds seem to be a little difficult. Yes, some of the offerings are not to my taste, but there are plenty of others to choose from. The best part of the plan is the health coach. A person supporting weight loss is what has been missing from all the other diets I've tried. It's great having someone cheering you on and giving great advice. The benefits far outweigh any cost monetary or gustatory. I no longer need to take crestor to control cholesterol, and my high A1c is now smack in the middle of normal range. Thanks Medifast and my health coach!

Perfect! Nothing has ever been more productive for effort spent. I think it is easy, takes out the guess work and you actually see weight loss weekly!

gain weight back if you don"t stay on their food. Some people have been getting very sick with it

I have been on it for close to a month. I like the fact that you eat/drink the products every 2-3 hours. Compared to other liquid diets, this is what works best for me. The thing I don't like about this program is the cost. It's about $300 a month.

Medifast definitely works! I started the program last summer around this time and lost 50 pounds in a few months which I have maintained. It has changed my lifestyle. The transition plan will help you to maintain the weight loss. My wife is now a health coach with Take Shape For Life so if you are interested in starting the program, please e-mail us at burhoe@teamtsfl.com ... you will have someone to help you with the program as well as additional discounts. Thanks!

I have had great success with this diet before and am back for the last time(I hope). Both the previous times I had medical issues which forced me off the diet with no chance to maitain. But this time I am sure it will work and I can be a Happier and healthier Me!

They also do not encourage exercise only after you have lost the weight you need to well sorry but exercise and diet go hand in hand.

posted Jul 10th, 2012 5:27 pm



Too expensive, and too restrictive, prefer the diet I am doing now incorporates fruits,, dairy, which this program does not allow gains the weight back once you stop eating their food. It does work if you only eat their foods, deviate and it all comes back.

I previously had tried medifast prior to my wedding in 2010, and I had lost 37 pounds in 3 months with not following it perfectly all the time.
Currently I am back on the Medifast plan and I have lost 6 pounds since last Monday!! At times it is hard but I know no matter what as long as I stick to it, it will work. I will continue to update my progress :)

I have been on & off the Medifast programs over the years, i've always lost weight, Now I've been back on since May 29th and I've already lost 11lbs as of today. I can't wait to update my progress with you guys. Some of the foods aren't that good, but some aren't too bad either. I stick mainly with bars & shakes let's see what happens.

posted Jun 8th, 2012 7:20 pm



This food is so awful that I have to hold my breath and chug it down. Each product I have tried is very gritty and tastes of cardboard with very little seasoning or flavor at all. Yes, I have lost weight, but it's probably because I spend many of my waking hours in the bathroom! I'm sure I would continue to lose weight, but I just cannot muster the strength to drink and eat this awful stuff. There has GOT to be a better way to lose weight and get healthy!

posted Jun 7th, 2012 7:15 pm



I just started the program today and it's not too bad. everything I tried was good I would say my least favorite so far is the pudding but I was still able to eat it. I am doing the online ordering with the personal coach and she is amazing. I first had gone into a local shop and was scared off by the insane cost just to "join" and then I would have to pay for food on top of that. For me the online deal was a no brainer and I am still accountable to my coach. After researching both before deciding I can say the only difference was a blood and metabolic test which I did not feel were worth the $1000. wish anyone else who wants to try the best of luck....I'm hoping to loose 30lbs in the next few months.

I was led astray by a representative that was going through a divorce who lost weight on it...worst thing I have ever done..biggest waste of $...food sucks..I puke ever time I opened a package..tastes like cardboard...drinking water and eating cardboard are not a healthy way to ose weight..then my "counselor" told me I was a failure and was never committed..thanks for the support...told me I didn't need microwave but I did...told me there was food I liked on list..there wasn't ,,the greens you can eat are strange..she gave me crap bc the only "greens" I like are green beans...seriously so disappointed by being led astray by an overly hyped representative who is only losing divorce pounds who is so insensitive..I lost more weigh by walking and cutting portions...DO NOT WASTE YOUR MONEY

I did this diet in 2008. I lost 100 ounds. Went from a size 18 to a 6. However, I got pregnant soon after my goal weight , and ended up gaining 80 lbs back. I've been trying to get back on track for 3 years. Once you go off, it is hard as heck to get back onto it.
