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.

Why should I trust your reviews? Don't you think the credibility of your reviews are compromised when you run ads along side them for the very products being reviewed? I was curious about Medifast and there were so many Medifast ads on the page I wasn't sure if I was reading a review or promo material.

Medicast does workIF you follow the program. I used it and the only reason it stopped working is because I stopped following the plan. My excuse was my birthday would come and I would eat whatever I wanted. By my birthday I would lose 50 pounds from Jan to may. I think it is a great,program and plan on following it and making it to maintenance. The food was fine once I figured out how to prepare it to my liking. Having the online support and a coach is the way to go, I was never a yo-yo dieter but Medifast is a plan I believe in. Good luck to all who try it,go one day at a time.

Medifast enrolment, Winter Garden Orlando Fl
I enrolled last week, on Monday, and started the program next day. I did not like the food at all in the beginning, but I told myself I am new with this food, just give it a chance. On the second day, I still didn??t like it and felt kind of sick, just thinking that I have to eat their special meals and snacks. 3 days later, I felt there was no way I could follow the program, so I got the contract and read that I could cancel within 7 days. I wrote a cancellation letter, faxed it and e-mailed it on Saturday so they would have it on Monday morning. To make a long story short, they sent me an e-mail refusing to give a refund. Now I have to go to small claims. Be aware that when you go to these places, they offer you the moon and stars to get your money. Make sure that they spell out how their cancellation due date actually works, because they turn the whole policy in their favor if you try to cancel. They should give you some trial food packets and then let you come back and sign. Do not let them use their high pressure sales tactics on you to sign their expensive ($1,000) contract. This, by the way does NOT include their food, which will cost you an additional $75-$100 per week. What a nightmare with this company! My recommendation is to study the pros and cons of any particular program before committing to it. If they insist on signing a contract and asking for money up front, RUN!!! We all know this does not end well with that kind of deal.

Need ideas for the Medifast lean and green meals I??ve been on and off the Medifast program for over a month. I have a hard time sticking with it faithfully. It??s easier for me during the day while I??m at work, but when I get home in the evenings I can??t stick with the lean and green meals. I find it hard to make dinner for myself and make my 5 year-old daughter something different. I know this program works if you stick with it, but when I??m home I??m finding it extremely difficult. Does anyone have any ideas for me? Also, can I still take B12 and Omega 3 vitamins to help with my energy?

I'm a 60 yr old male with diabetes. I have not been able to control my blood sugar in 15 years. I've had to keep upping my oral medications until I maxed out and then went on insulin.
The 2nd day I went on the Medifast diet my blood sugars stabilized. Within a week I got off the insulin shot at night and only remained on oral medications.
I kid you not. I was shocked how this diet has changed my life. I credit it with SAVING my life.
I was 241 lbs on 1/1/2012. It's now 4/16/12 and I'm down to 193 lbs.
And I've done some cheating on this diet too but mostly stuck with it.
The bars, shakes, pizza chips etc are my favorites.
Another good thing about this diet is it takes the indecision out of my daily life on what to eat for the 5 meals per day.
When I eat the one personal protein/vegetables/salad each night it fills me up. Your body becomes accustomed to eating healthy small amounts of food.
I've never been able to lose weight my whole adult life. Everybody always talks about losing weight but not many accomplish it.
Everyone who sees me marvels of how good I look and how I quickly I lost the weight.
I went to an orthopaedic surgeon the other day and he was more interested in how I lost my weight than my surgery.
He needed to lose weight himself.
If I can do this, anyone can and I'm not trying the bull around.
This diet works.

I have just begun my 8th week on Medifast. Have lost 27lbs during the first 7 weeks. I am one of the users that has not had any major problems and I have been able to follow the instructions to a T. The only downside (sort of) for me is that I am very tired at the end of the day - but during the day I have much more energy and none of my previous aches and pains. I say it's only sort of a downside as I now sleep really well and do not have problems waking up - issues I had before starting MF.

I have no doubt this program will not work for everyone (what one does?), but it's worth at least checking out if you can afford it and want fairly quick, steady weight lost. Not only am I losing weight, but I haven't felt this good physically in years. Even though it's a meal replacement program, you can learn many skills for proper eating and nutrition - if you want to learn. If you get tired of the food, there are many, many tips & little tricks to change it up and make it more to your liking.

I started out with ordering 2 weeks of food to see if I could handle it - that would be my recommendation is to give it a small try and see if it might work for you. Again with the caveat, IF you can afford it.

Great program! Lost the weight I wanted, FAST!!!

I started the program last week and find it is very manageable. Before I started, I did a lot of research and collected many receipes. As a result, the food has not been that bad. As a personal conviction, I have decided not to weigh myself or take my measurements. I want to see if this program is real. What is real is when I put on my clothes and they no longer fit. What is real is when I get up and have more energy. What is real is when I begin to look at my progress and decide on making better food choices. At the end of the week, this is what has been real. I stay within the food guidelines and I have noticed small changes. I will continue this program until my vision becomes a reality.

Started 3 weeks ago and was skeptical. I have lost 15lb in three weeks. I feel great. Due to the low sodium etc my hands and feet are no longer swolen. I have lost one dress size so far. Looking forward to losing more.
The structure of the lean and green has helped me to cook healthy meals, which I hope I will continue long after reaching my goal weight. I actually look forward to coming home & cooking for myslef instead of picking up unhealthy fast food. I do not feel I am depriving myslef & It fits easily into my busy lifestyle and work schedule.
The starter pack is OK, but you will need to add to it. I find the bars and shakes are good if you are on the go. The soups are good. Don't like the chilli, but overall no problems with the taste of everything.
I also really feel this is something I can stick to, and can also turn back to easily if I start to gain weight again.
Yes it is expensive, but I honestly think I am spending less overall on food than I used to.
Oh and for dinner last night I ate a nice cut of Fillet Mignon, Mushrooms, and a plate full of asparagus, with a serving of ranch dressing as my healthy fat drissleled over the asparagus.
I urge you to try it. If you are not losing weight on it, then you are realy not sticking to the plan. 8 glasses of water a day is crucial, and no alcohol.

I just started the 2 week trial program to see if I could stick to this and what the food tasted like. They sent me 2 weeks of chicken noodle soup, 2 weeks of oatmeal (which i have never liked) and a variety of shakes and brownies. There is no variety the same food day in and day out. I don't care how good or bad the food would be that is boring. I am not sure I will be able to last a full 2 weeks, eating the same thing everyday! I am very disappointed and the food does taste terrible.

posted Mar 19th, 2012 9:22 pm


I think the problem most people have with the taste of the food is due to the fact that our society is used to food that is loaded with sugar, sodium, artificial flavors and sweeteners. It takes a while for the taste buds to grow accustomed to food without those ingredients. Once you adjust, you'll find that the high-fat, sugary, artificially-flavored foods you once enjoyed don't taste as good as you remember. That makes it easier to transition to whole, natural healthy foods whr you can actually enjoy the taste of real food. Medifast is just a bridge to get you from where you are to where you want to go, and if you are truly motivated to reach your goal, the taste of Medifast food becomes a non-issue. Good Luck!

I'm a Take Shape For Life Health Coach, and I believe, and my clients would testify, that the key for long-term weight management is lifestyle change. Most people can't do that by themselves, that's why my coaching business is thriving. I help people set health goals and support them through the process, at the same time teaching the Habits of Health. 85% of people who lose weight on diest gain it back - plus about 10lbs more - within 2-years. With a health coach, it's almost the opposite. More people are successful because of the support, encouragement, and accountability. Please feel free to contact me if you're interested in more information about health coaching.

It's very important to become involved with the online MF community. There you learn things like the fact that if you soak the soups over-night they are much better. That if you stick with it, your tastes will change. Can't count how many people hated the oatmeal in the beginning, but later came back to it and loved it. The MF community members will also give you lots of tips on how to prep the food. The information on the packets isn't always the best way to do it... and for folks saying just the same # of calories in "real" food... it's not the same. The MF meals are vitamin fortified. If you try to eat the low-level of calories without the suppliments added to the MF meals, you'll be under-nourished. The MF meals are formulated to keep you out of starvation mode. The MF nutritional support will advise how to modify the diet if you want to exercise (i.e. a 4-2 plan instead of a 5-1 plan), because if you increase the calorie deficit too much by exercising a lot, your body will start conserving fat instead of shedding it.

Btw, your example MF meal above is misleading. I've yet to see a 7oz tilapia fillet. When I measure out my 7oz of tilapia, it usually works out to 6 or 7 tilapia filets and I have to split it between two meals (meaning I actually end up eating two lean and green meals that day, for a total of seven meals). Also, during the 5-1 phase, you would not have sugar snap peas or carrots in your lean and green meal!

I've been on it since October and have lost 40lbs.

Again, anyone who decides to give MF a try, please, please, please connect with the community for guidance and support. It makes all the difference.

The food tasted horrible. I tried it for 4 days and it never got better for me. I am sure you can loose weight with it because I want to throw up everytime I eat...Do not recommend this at all!

Hi, I have been on medifast for almost three months. I have lost almost 40 pounds since I started. Yes you do need to find out what you like and what you do not. I loved the bars and the soft serve. I did hit a stand still for a while. it seemed like no matter what i did i held at a certain weight. I got discourage but kept at it. Now Iam strarting back down. I found out that I need oatmeal for breakfast and that keeps me feeling fuller all day long. don't know why but right now I am not questioning it. Keep with it as it does work if you work it.

I started this diet on February 7th because I was tired of feeling FAT. My friend and I am are doing it together. I have lost 10 pounds so far and I am still working towards losing 10 more. The food is diet food. Try a little of everything too see what you like. I eat the blueberry oatmeal for breakfast, the bars for snack, the soups for lunch and the pretzels or chocolate shakes for my other snack. I have my lean and green for dinner and then another yummy treat which is their chocolate chip cookie. It is yummy especially when you cook it in the oven as well as the brownie. DO IT and you will lose weight. I have struggled my whole life losing weight this is the first time I have actually lost weight. So thank you medifast!!!!

worst tasting stuff

The food was AWFUL! It all tasted like cardboard! The eggs are powder, the soups are all dehydrated so they are crunchy and inedible, the protein powders are thick and taste like baby formula, it just hits the back of your throat...I am on my 4th day and yes I have lost 4 pounds, but that's because I only eat half a protein bar cause it takes me 15 minutes to get it down between the gagging..i am only eating half of everything! it's awful! Take their idea...high protein, low carbs, 5 100 calorie meals a day, and 1 small veggie and lein meat a day and you will lose weight with EDIBLE food

I need to lose 15 lbs. I went on Weight watchers and followed it to the letter, weighing everything, exercising, etc. It took me 5 months to lose 5 lbs. I got so frustrated I went off the diet and gained it all back. SO I decided to try Medifast. So far so good...I have lost 5 lbs in 1 month. I figured out what I like, the dutch chocolate shake, the bars and the brownies and the Maryland crab soup. I think it will be easy to live off of that for the next 2 months so I can take off all the weight. Try works!

I started this diet because I gained a tremendous amount of weight during my 2nd pregnancy in 2003. I stayed overweight from 2004-2009 and in return my health suffered including my feet, hips, and legs. I was in so much pain from carrying the extra weight that I told myself that I'd rather just die. I couldn't play with my son or walk far without the hip pain making me cripple over in severe, throbbing pain. I couldn't do anything I wanted to do anymore and slowly became a recluse. I was just a shadow of my former self. So, at work a friend/co-worker told me about a diet called "Medifast", she gave me a few packets/bars of her stock and told me to try it out for a day to see if I liked the food. I did like the food, I mean it's definately "diet food" doesn't taste gourmet or fatty but it is not inedible like some posters say. I decided in March of 2009 to fork over 250 something for a month's worth of food. The first few days were hard, I won't deny that. I felt hungry and tired. Also at first I would weight myself daily because you drop 1-2 pounds a day the first week or two and it was motivating me to stick with it; however during week 3 I lost nothing, at that time I didn't know that's a common thing because your body is adjusting. I also could not drink wine anymore which was extremely difficult for me to adjust to because I loved having wine during the weekends. Anyway, I stuck with it and at 6 weeks I had lost 22 pounds. I continued to stick with it and within five months I lost a total of 89 pounds - went from a size 20 to a size 4. My hair did not FALL OUT, some do and some don't and my gallbladder did not go crazy like some report; in fact my severe PMS and period issues went away - I would have severe cramps, bloating and fatigue all my life and those symptoms completely went away during the program. Here it is 2012 and I've been on the maintenace program since my weight loss and have not gained anything back - nothing! I have muscles now and run marathons. I make love with the lights on and wear all the cute clothes that show off my healthy figure. I have energy to do anything I want and my depression is completely gone!!!!! Yes, it's a diet and yes it's hard at first but you got to want to LIVE because when you are fat you aren't living you are DYING!!!!! I would have rather just withered away and died than continue to stay overweight. I was so miserable and Medifast helped me change my eating habits and yes YOU CAN DO ANYTHING YOU PUT YOUR MIND TO!

I just started the Medifast program a week ago. So far I am completely satisfied. I staeted out by getting rid of all the food in the house that would not comply with the diet, living alone makes this easier. I keep to the progeam, to a T, and was extremely suprised when I had my first weigh in this morning. I lost 12.6 lbs. I read several reviews and one mentioned disiness and almost blacking out. I have a fairly active day at work and I have not frly any of these symptoms. I actually feel no different than prior to starting the program. I do realize that everyone is different. However, I think that was a rare case. Well, I have 79 more pounds to go. I just keep my mind set on the goal and stay positive!!
