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.

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.

Medifast does help you lose weight but it is just as unhealthy as most of the other meal replacement programs out there. If the food wouldn't benefit a thin person , it doesn't benefit an over weight person either. people have to remove the thin is healthy lie from their thought process and investigate all natural, nutritionally complete, health programs that ALSO have the side effect of weight loss.

I am one week into this program. Have lost almost 5 pounds. I find it interesting that anyone one hear would claim that I haven't done my research...I have. I realize it is high protein, low fat and low carb...basic. I know what to do...I just have a very hard time executing it without structure. I am a working mom with 5 kids and 1 granddaughter. I am a very busy person with little time to shop and prepare for healthy meals. Not on this plan. I have food for the entire month. It is practical for someone like me...

I've lost 73 pounds in 6 months. I feel better than I have in years!!! I'm healthy, lots of energy. If I'd known it would be this easy, I would have done it sooner had I known about Medifast. I've done every diet imaginable, but Medifast is the only one I have lost this much weight with, and now I have the tools I need to keep it off forever. The best part? I look and feel younger! No saggy skin or lose of muscle tone like other diets.

It is working for me! I am so glad it is a lifestyle change! I have lost 57lbs in 11 weeks! I eat 6 meals a day and exercise about three times a week. This program is fast, simple, and convenient! I cant believe it! I am half way to my goal!

In 2008, I lost 20 pounds on Medifast in 20 weeks. Now I have gained back 12 of those pounds, partly because of stress due to my husband's illness, and partly because I fell back into old habits. I want to get back on Medifast, because it was the only plan that worked for me. Hopefully, I can get in shape before summer.

This is an easy to follow plan that yields very quick results. It is all laid out for you so you don't have to think about what you are going to eat and in what amount until you have your lean and green dinner.

posted Jan 8th, 2010 7:32 pm



I tried this plan after a friend lost 25 lbs this summer! I too had about 25 to lose and it sounded like something I could do. I have lost 20 lbs and have 5 to go in just 11 weeks. My husband started at the same time and has lost 47 lbs. It works, it is easy and convenient, and I no longer crave fast food and high fat comfort foods. I haven't felt this good in years. I love and support this program so much that I became a health coach for TSFL. This program offers the popular medifast meals plus a free health coach to help you along the way. This is really important for success. I used my health coach a lot in the early weeks, and I still talk to her everyday. Email me for more details...

This diet is filling someone's pockets with gold. They first hook on the diet plan. Then you get the TSFL plan. Can't believe people don't research this. It is a high protein diet that comes in a powder... Just stick with leans meats, green vegetables, and exercise.
And for the ones who say that the food bill has went down....Baloney...
They plant that seed in your head. I have personally witnessed a couple of the TSFL people chase down overweight people telling they can fix their life.
I was personally over weight, border line diabetic, and high blood pressure. I done my research, cut out the cola's and the sugar, white bread and few other things. Got a treadmill started slowly at 15 minutes at first now I do at least and hour a day. Lost 95 pounds 2 years ago and maintaining. I can go to a resturant with friends and eat.
So for those of you who just want to make your coaches and the company pockets fatter thats your choice.

Medifast is great! Keeps you going all day!

I just wonder how "Anne" can blame losing cuticles and nails from this diet?

Medifast is by far the best weight loss program I??ve ever tried! I love it, and although I??ve bumped myself out of ketosis several time due to a birthday party, family reunion, and a concert, I??ve still lost 25 lbs. and 2 pant sizes, in less than 2 months! I can??t wait to lose the other 35 lbs. that I have to lose! And, because of all of the nutrients I??m getting, my nails are growing like crazy! It takes dedication, but it??s so worth it. It has changed the way I look at food! And, the people that say you??ll gain all the weight back, obviously missed the whole point of this plan. You can??t go back to eating the way you did before Medifast, and you have to exercise! It??s a lifestyle change!! If you??re desperate, try it, and remember that it takes about 3-5 days to enter ketosis, but once you??re there, you ARE NOT HUNGRY!!! Which, for me, is a wonderful thing:) It was so much help to have my health coach (miofit.com) just hold my hand thru the whole process. Almost there!!!
