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 have been on Medifast for about two weeks. There are 70 choices of food to choose from including oatmeal, soups,
shakes and bars. I am on vacation and unable to weigh myself but the first week, I lost 6 lbs. I only have 30 to lose so I was thrilled with losing that much in a week. The food is edible and the plan works!!

Horrible taste, I could not get though one afternoon on this stuff, wondering why I spend the money, I could cook an egg in the morning, light soup for lunch, eat a lean meat and vegetable for lunch and would have lost just as much weight. I don't understand how people eat this stuff...

I loved it. Lost 50lbs in 4 mos. It was very easy combined with gym time.

I found the only way it works is you have to have a very regular daily routine. Minimize after hours work functions. Remove yourself from social influance and NO alcohol.

It works, no doubt about it. But you have to commit to lifestyle changes.

I will say this it works. BUT be prepared for light-headedness, I got blacked out vision as if I were ready to pass out. It IS a LIQUID DIET. The soups U see are WATER those bit and I mean bits of veggies in the soup float to the top its not all through the soup. You dont need to work out. U dont have the strength so be SMART. CHECK with your doctor first if you have HBP( High Blood Pressure OR Low Blood PREssure) This is a tough diet and you definantly feel woozy on it, empty like you haven't eaten. I think this should be kept for hospital use. Hospitals would make good money accepting in obese people and using this plan. But I feel U should visit your doctor every three days - until you get used to the diet. BE WARE... if U go back to eating pasta, pizza sandwitches you WILL REGAIN EVERY OUNCE and some.

Buyer Beware

Been on the program for a year in a half. Lost 60 lbs out of my 120 I was going for. If you have food allergies don't bother doing this. I wish I would have researched this more before dropping all the money on this. I'm allergic to nuts & since joining I've become allergic to soy & dairy. That is over half of the food they offer. I have a very active physical job that this diet does not give you the energy or the feeling of being full. I was happy about losing the weight I did, but very difficult with the food choices they offer. What I'm not allergic to taste horrible.

My first 3 weeks on Medifast have been very rewarding. Between the convenience of the 5 Medifast meals and the 1 home cooked Lean and Green meal, I am never hungry and the cravings are gone. My doctor was very pleased when I saw him after 8 days on MF. My fasting blood glucose decreased around 40 points and I lost 18 pounds. These improvements came with Medifast being the only difference. No exercise, no medication, just Medifast.

My doctor and I are both big fans of Medifast.

Medi-fast is VERY expensive.
Look at the nutritional content of the "meals". Basically you get 5 100-120 calorie powdered food like substances a day and a 400 calorie meal you prepare yourself a day. Of course you'd lose weight, because you are starving your body!!!
For starters, their powdered eggs are a much pricier (and nastier) version of egg beaters. Buy some egg beaters and eat 100 calories of those. Or 2 hardboiled eggs (medium) will cost you 125 calories, only 15 calories more than a powdered egg packet.
Lots of companies make low cal protein diet shakes and bars, And those cost about 4-6 dollars for 5-6 portions, and oftentimes less. You can replace a snack or two wtih those.
How about a baby bell cheese and some celery sticks instead too? Or heck some nut butter and celery. Their items are 7 portions for 17 dollars!!!! even their cheapo powdered soups!

I've lost 12 pounds this month on eggs cooked without oil (or just a spray), lots and lots of homemade soup, trader joe mini brie bites, lean protein and veggie dinners, 93% lean ground turkey, my mom's borscht recipe with beans instaed of potatoes and a little low fat sour cream.
Eat sensibly. And eat more than 1200 calories a day. When you eat too little you lose weight, but in the wrong ways. You lose muscle (hence the people who mentioned they had a hard time exercising on the program) and eat more protein and fewer carbs. When you do eat carbs eat complex ones.
A great breakfast? 1 serving of steel cut oats (made with water), 1 tblspoon almond butter unsalted and unsweetened, and some unsweetened frozen wild blueberries or peaches or half of a fresh banana. If you really want to do the tiny meal thing then have half for breakfast and the other half for morning snack.
Then a baby bell cheese round (low fat if you want to conserve more calories) and some celery sticks... You get the idea. Pre-portion things for yourself and eat real food. Drink a slimfast or eat a fiber one bar if you need to too. Just be smart and save your money and don't eat powdered junk.

I am pretty sure you will lose weight on the medifast diet. The reason being is the food is so nasty, almost inedible that you will probably be starving yourself from the many skipped meals and passes on the food. This is absolutely the most gross food I have ever eaten. Please invest in a healthy cookbook and skip this waste of money!

posted Jan 23rd, 2012 5:33 pm


The BEST food supplements ever!! The meals are NOT inedible. The "shakes" are NOT powder floating in water. The "bars" are NOT a little rice with something on them. Honestly, waste your money. You will lose weight because there is NO sugar in there, but you will be able to last because the food supplements are so good.

I did this program a few years back and it started out good and turned to crap.
I had hit a plateau and the counselors I had told me I needed to cut back on my cardio.
They tried pushing more products on me.
I cringe every time I hear their commercials on the radio .

I joined Medifast in Mid April 2011, and as of September 2011 (4.5 months) I lost 45 lbs. Now I am on Maintenance and doing fine. I still have 1 medifast meals a day...mostly the hot capuccino....what's not to like about a breakfast that has fiber, high protein, and only 100 calories---did I mention it tastes great as well. Generally speaking,
the food choices and food items are excellent. You really must find the items that suit your palate.....for me it was the Maryland Crab Soup, Beef Stew, BBQ Bites (think BBQ flavored & pretzel-like), the Brownies (Kaboom!!!), and Lemon Mirangue Bars, and Chocolate Shake (with appetite suppressant) I said, you've got to find a niche for your own palate. I recommend exercise 2 to 3 times a week....this makes the weight loss and transition back to 'regular' food easier. I emphasize 'regular' because even when you are on maintenance you are still in a medifast state of this I mean you are a stickler for portion control, you stare down candy bars and walk-away with a victorious smile, you prepare your healthy snacks and lunch the night's like being a member of Seal Team 6 taking covert action against regaining weight. When you are on maintenance you come up with all kinds of things to keep you on the straight and, having a jar of peanut butter in your desk (at work) for that quick 1 teaspoon 30 calorie snack. Bottom line, this is a great diet program and it helps you to change your mindset towards food and eating. Its all about the lifestyle change. Hope this was help. A toast to success with your weight loss pursuit....with Medifast you'll see the results quickly and enjoy the journey all the more.

Forgot to mention, if you sign up for auto-ship and your shipment is over $250.00, the shipping is free. You can customize your shipment and get only the items you prefer. Aso if you own/use a personal blender (they also sell one) the shakes, soft serve and puddings turn out better. The oatmeal was the only thing that I thought tasted like vitamins and minerals that they add in. I use a little sugar-free pancake syrup in it and it tastes better. You can be very creative with this plan and there is so much that you CAN eat while on it. Just don't over-do. If you do cheat and gain a few just go back to the plan and within two to three days you will be back on track. Good luck.

I have lost 22 lbs on MF so far. I like the food. If you research Mf recipes you have much more choices. I make muffins using the oatmeal, egg beaters and b.p. Also you can make bread using tomato soup, add condiments and lunch meat and you've got a sandwich. Using the broccoli soup, you can make mini quiches,(3= one meal) Without some of these recipes, I would be very bored just eating what they provide. I plan to stay on this diet until I reach my goal of 30 lbs. This one is the only one that has worked for me. Good luck everyone and be patient.

I've been on the diet for about two months now and I have gradually lost 2 to 4 lbs a week. I exercise regularly, but have noticed that exercise doesn't seem to accelerate my weight loss. More importantly than weight loss, I notice better fitting clothes even for the difference of a pound or 2. As to the foods, I love the eggs, oatmeal, nutrition bars, pudding, and cheese bites. I am not much of a fan of the milkshakes, which is why Slimfast never did it for me. It did take a little while to get use to the food, but when you restrict yourself like this, you soon learn to enjoy them. I'm just being honest about that. I've lost 28 lbs to date, and I have another 40 to go. People everywhere keep telling me not to lose anymore. Baloney. I am going to get to the right weight no matter what. What I like most about medifast is that it has taught me something about quantity control and making sure I eat throughout the day. Before that, I would eat 2 to 3 very large meals, that I thought were healthy and therefore justified. I'm glad to finally break that nonsense.

I am waiting for my food to arrive so I can start the program. I ran into a friend about a week ago and she had lost 450 pounds. I was in such shock when I seen her. I asked her how she did it and she told me MF. So after talking to her I decided that if she can lose weight like that, I can lose the 40 pounds I need to lose. It was such and inspiration talking to her and seeing her after all that weight loss...

I love the flexibility of the lean-green meal. I usually opt for chicken or fish with a spinach salad and another veggie.
