Medifast Diet Ingredients and Side Effects

Here are some common ingredients added to Medifast’s prepackaged foods:

Soy Protein Concentrate

Soy Protein Isolate

Milk Protein Concentrate



Artificial Flavor

Xanthan Gum


Acesulfame Potassium

Modified Food Starch

Guar Gum



Maltitol Syrup



Soy Protein: This soybean extract is often GMO unless otherwise stated. According to Health Research Funding:

“May cause mineral deficiencies… Soy products have some anti-nutrient contents”

“Blocks calcium absorption… soy products contain phytic acid, a natural plant based substance responsible in blocking calcium and some other valuable minerals”

Soy has issues due to its natural components which may decrease the amount of minerals the body absorbs.

Fructose: This basic fruit sugar is often added to processed drinks and foods as a cheap sweetener.  A clinical study performed by the University of California Davis found that it was:

“associated with the insulin resistance syndrome…. May be detrimental in terms of body weight and adiposity”

Not only did it fail to suppress appetite, but it’s been shown to have damaging effects on metabolism and overall health.

Large amounts of it are stored as fat which can potentially increase the risk for cardiovascular diseases.

Guar Gum: Common thickener extracted from the guar plant. Web MD describes its issues:

“Side effect include increased gas production, diarrhea, and loose stools”

“can cause blockages of the esophagus and the intestines”

It’s often added to processed foods as a cheap binder and thickener.

Sucralose: Artificial sweeter which is around 1,000 times sweeter than standard table sugar. It has no calories since the body cannot use it.

Studies have been performed which showed this ingredient was potentially dangerous. A study by Duke University found:

“Alters Gut Microflora and Increases Intestinal P-Glycoprotein”

This can be potentially damaging to the immune system, and when eaten, sucralose is considered a toxin according to this study.

A list of the top 10 ranked diet plans are made available in the link provided here.

Web MD has this to say about the Medifast Diet:

“those extreme changes may make sticking with the program a challenge”

“this is an extreme diet, so don’t try it without talking to your doctor first”

They call it extreme due to the 800 to 1,000 calorie limit a day that is suggested. This is extremely low and will result in weight loss, but it can be difficult to maintain.

The Achieve plan offers:

  • 4 Medifast meals: 70 different food options are offered such as sweets, soups, pastas, bars and shakes.
  • 2 lean and green meals: This is separate from the prepackaged meals. One choses 3 servings of vegetables. 2 servings of healthy fats and 5 to 7 ounces of lean protein from the menu offered.
  • 1 Healthy snack: This can be a serving of fruit or yogurt, a baked potato, whole wheat pasta, or several other offered foods. Also separate from the prepackaged foods.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

Medifast Diet  Quality of Ingredients

The ingredients added to the prepackaged foods are commonly found in other processed meals. These cheap additives are potentially unsafe, and they can actually make it harder to lose weight.

The added fructose, artificial additives, binders, and cheap thickeners are not quality ingredients. They may also make it harder to sustain the diet.

An 800 to 1,000 calorie a day diet is recommended, which is considerably low. Web MD has this to say about liming calories:

“Women should not restrict themselves to less than 1,000 calories per day… men to less than 200 calories per day without medical supervision”

When reducing calories to such a small limit, there’s a possibility for nutritional deficiencies and side effects. This is why this limitation is often only suggested to people under strict medical supervision.

The Price and Quality of Medifast Diet

Pricing can vary, but Web MD says:

“a 4-week supply of meal replacements will cost at last $300 plus shipping”

The foods offered are low in calories, but they’re also often loaded with artificial and processed additives. These kinds of ingredients can be found in other processed foods for much cheaper. The only difference is that there are fewer portions offered.

Health USA News also says about Medifast:

“It doesn’t perfectly align with the government’s guidelines for healthy eating… provides a little too much protein and too few calories”

“At 800 to 1,000 calories a day, it also dips low for many diets”

Both the kinds of foods offered and the limitations on calories make this a poor diet plan. There’s far too much of a risk of not being able to stick to the diet due to its extreme limitations. This is not suited for all people, and it’s the reason why many customers said they couldn’t continue with the Medifast Diet.

A list of the highest rated diet plans is made available in the link provided here.

Business of Medifast Diet

Medifast, Inc. is the name of the group; their contact information is listed as:

Phone Number: (800) 209-0878

They settled a $3.7 million dollar lawsuit for making false weight loss claims of:

“Medifast 5 & 1 plan…. (could help) lose up to 2-5 pounds per week”

The Federal Trade Commission found:

“did not have a reasonable basis in scientific evidence to support the claims”

They also have complaints on Consumer Affairs and Rip Off Report.com. Here’s what some customers had to say:

“I did not sign up for an auto renew account but my account automatically auto renewed”

“They always sign up for automatic shipments”

“terrible customer service & absolutely don’t care”

“They will not give money back”

Many users were concerned that the company did not allow for a money back return. People also said that the customer service staff was unhelpful, and that they were constantly put on hold for long periods.

Customer Opinions of Medifast Diet

Here are some customer quotes about the Medifast Diet:

“Horrendous food, very costly, total disappointment”

“My stomach was constantly turning; eventually the gas became so bad”

“The food was extremely horrible and made me feel so dizzy and weird”

“The “food” tastes like cardboard and is NOT healthy because it is full of additives and preservatives”

The majority of reviews on the food were negative. Many were concerned that there were side effects, and that the food tasted artificial. For many it was impossible to continue using the diet. Some people did manage to lose weight, but this is common in low calorie meal plans.

People did complain about gas, bloating, headaches, nausea, fatigue, and hair loss. This caused many concerns in people, as they were uncertain as to what could have caused these symptoms.

The overwhelming consensus is that the food options are not very good, and that they’re full of unwanted cheap additives.  The top 10 ranked diet plans list is viewable when you click here.

Conclusion - Does Medifast Diet  Work?

The Medifast Diet consists of pre-packaged low calorie foods, as well as diet advice and suggestions for grocery foods. Though it’s comprehensive, many users have said the quality of foods is poor, and health sites like Web MD have confirmed it’s difficult to maintain. Customers were also often disappointed with the high amounts of artificial ingredients, and potentially harmful additives. This includes things like binders, cheap sweeteners which can cause metabolism issues, and GMO additives.

Our experts have rated many different diets, and the highest ranked one of 2016 was the 18Shake Diet. It offers 2 all natural supplements, an appetite suppressing high protein meal replacement, and a metabolism boosting stimulant free diet pill. Customers have left glowing testimonials and opinions on the 18Shake Diet. Both combine to help provide weight loss benefits such as increase metabolism, improved digestion, well-rounded nutrients, and many other benefits.

Both supplements are backed by a full 30 day money back guarantee. All purchases are supported with this no questions asked risk free policy. Discover more information about the 18Shake Diet Plan by clicking here.

I went on the plan January 17, 2011 to lose weight before my son's wedding.
I lost 100 pounds in under 8 months. I think the food is good, what i don't like I return. It's easy to follow and I really like it but you need a coach. I went off for the wedding, and gained 10 pounds in 2 weeks because I just started eating regular food and not transition style. I am back on it until Christmas and hope to lose another 50. I never did any exercise so I am going to try now.

I just got my shipment today for Medifast. I have 16 lbs I want to lose. I'm excited about it. I've used Nurrisystem in the past with good results, but I wanted to try something different this time. Over the last year and a half, I've gained all of my weight back.

I just started the diet this week, so far I am having a really hard time adjusting to the food. By yesterday I felt like giving up. Anyone out there feel the same way? Please help....

I am 58 years old and have been trying unsuccessfully to lose 10 lbs for the last 15 years. I saw my niece who had lost 85 lbs and asked what she did. It was Medifast. I ordered it and started it. I have lost 14 lbs. in about 2 months. It has been the easiest diet I have ever done. I don't have to make much of a decision of what to eat. Just grab an envelope and mix. 2 minutes preperation...tops. So quick and easy. I love most of the meals. Couldn't tolerate the broccoli soup. It was gross. So is the Capacino. Everything else is really tasty. I have only cheated once and got right back on track. Knowing I paid over $350. is motiviation for staying on it. I have realized what I put into my mouth mindlessly. And I think I can do well once I transition off the product. I finally feel in control and I look great. I love Medifast.

I started this diet over a week ago. I purchased my supplies on Ebay. So far I love it. In one week I lost 7 lbs. Some of the food is better than others. I do not like the vanilla flavored items and the mint chocolate bar is gross but everything is at least edible. I have enough supplies for about 1 months. At that point I will decide whether to stay on it or go on a medically supervised meal replacement program . I have a significant amount of weight to lose and am a little bit leary of doing it long term with no medical supervision. I also had to adjust the calories. I know you are not supposed to excercise on it for the first month but I have to swim to keep one of my knees from being extremely painful. I just figured out how many calories I burn swimming and replace half of them with a low sugar fruit like berries or yogurt.. The weight is still coming off me and I am not in danger of making myself sick. I have high hopes for this program because so far I love it!!!!

I have been on Medifast for 1 month I have lost 10lbs 15 inches I fill great and I still have a month to go. This plan keep me full and not craving for other types of food.

When u have a significant amount of weight to loose, and u loose it, hairloss happens. Most individuals who have an extra 100 or so pounds to loose will experience hairloss no matter the plan they use. Eg- Richard Simmons' curly fro that he is known for is a result of hair plugs. He does not hesitate to say so either.

My hair fell out and I was told my gall bladder was in trouble after being on it about three months. You will lose but you may have bald spots. Check out the actual medifast site where the actual medifast dieters post and you will read so many medifast users losing a scary amount of hair

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.

I love all of the bars and the snacks (puffs, pretzels, bites). Salty/crunchy has always been my downfall and these options offer me a lot of indulgence. One of the most important things I can pass along is to read the "Take Shape for Life" book that comes along with the program. I have yo-yo dieted all my life. This is a life altering process you're undergoing. If you understand the dynamics that go behind it, especially the psychological ones, it WILL help you through. My biggest was fear of failure. Seeing the immediate results (15lbs my first week) has given me the encouragement to continue. My goal is 100 lbs and I'll be the weight I was at 18 years old. If I make it, great, but if not, I'm not going to beat myself up. I'm already weighing less than I have in 10 years and have gone from siz 46 jeans to 42.

Good luck everyone. You're worth the effort.

Ladies and Gents, Im a 20 year old male. I was in need of losing weight. I played sports all my life, and gained a lot of weight after a sports injury. After my first year of college i gained even more, reaching my max weight in May 2010 of 430 pounds.. yeah a bigg boy. I started the program in Sept. 2010, not really knowing what to think, well let me tell you, its amazing. Yeah so some of the food doesnt taste the best but ur health is more important, so live with it, cant handle it.. then i guess cont. to be over weight..!! Yes you dont feel that well the first two weeks as your body is going thru some major changes. Fight it off and you will start to feel wonderful.. Yes, you shouldnt exercise for the first month. But if you follow the dang program IT WILL WORK.. hands down, no questions asked. I recently got back from the National Conv. in Orlando FL. And the ave. weight loss out of the 2500+ people there was 60 pounds.. Still want to complain to everyone it doesnt work..? Plain and simple, if it didnt work for you, YOUR doing something wrong, not the program..In less than one years time I have LOST 150 POUNDS!! HOW...? i stuck to the program and dont cheat. I run every other night, i lift weights on the other nights, i swim, i walk, i enjoy life again. YOU CAN DO THIS.. Medifast and the TSFL program has honestly given me my life back. I have more energy than ever before, i need less sleep because i get better quality sleep. I can think sharper on a daily basis. For those of you that say its too costly, well let me put it this way, can you actually put a price on being healthy and happy..? I know i cant..? Find YOUR WHY.. the reason you need to drop weight.. your reason to be healthy, and feel younger. Find some determination and dedicate yourself to the program...IF A YOUNG KID CAN DO IT.. WHY CANT YOU...?? THERE IS NOT A BETTER PROGRAM THAN THIS ONE.. its safe, fast, and easy.. GOD BLESS AND GOOD LUCK PEOPLE..

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!..and also someone was saying that it's full of artificial ingredients..not so ..read the nutritional info on the box or on their website. The other thing is someone was saying that they don't eat the bars because it held their weight back ..again..not so..all the meals are interchangeable and you can mix them up or eat the same meal every 2-3 hrs and it won't change a thing. Oh and one more thing I really really need to mention..one post said that you can go down to the Walmart and buy similar items ..sorry, this is definitely not true and I bet if I spoke to that person that posted that today ..she would still be exactly where she was weight wise when she posted the post....If it was that easy..we all wouldn't be on here talking about our weight issues! Instead we would be going to Walmart;)
I will tell you one thing about this program for me it was the easiest thing I have ever done. . eat a meal every 2-3 hrs drink water.."SIMPLE" Seriously it was that easy! I think if you want something bad enough and you are ready it will work and you won't sabotoge yourself. Just know that with any program you will have some adjustments in the beginning. And again after you are off of the program. It is a way of life and your body and mind will love you for it! Some people had said that they thought it was a con..trust me on this that it is very real I am living proof! Just to keep my self in check and share the wealth with family and friends I became a health coach. I am a real person with real results ..when nothing else worked this was my saving grace and I thank God everyday for showing me the way! Feel free to contact me with any questions you may have I would be more then happy to answer any questions you may have.

Medifast does work and is the easiest to follow.

I have Celiac Disease (evil Gluten), and I must commend Medifast for looking to help all possible customers out there. Once I started to adjust my diet for my dysfunction I began to gain weight and have a very weird relationship with food; I could/can never stop thinking about it. I needed a simple solution to lose about 15 to 20 lbs (I'm not really overweight like many doing this, but need to make sure I don't gain too much in the future and remain a healthy weight). I tried Weight Watchers but since I can't eat their microwave meals any more(and I don't cook) it wasn't simple. Nutrisystem also has no options in their delivery system for people with allergies(My mom does nutrisystem and loses about 2 lbs a week). While I must admit not all of Medifast's meals are fabulous they do keep keep you pretty satisfied. You never really feel deprived because you can enjoy that one good meal a day. I have a very crazy schedule, but I am managing to work this into it. The shaker jar they give isn't too great, so I bought a Zyliss one that is made for protein shakes. It blends it perfectly. I recommend this diet. I feel it is simple to stick with and you see results quickly. I started less than a week ago, but already feel less bloated and fit in my clothes better. Good luck all!

I love it. I was desparate to lose weight. I tried nutrisystem for two weeks. No results. I only do the shakes 5 a day and lean dinner...and I FINALLY am losing. Im not young and am middle aged and feared gaiing more and more was my destiny. The shakes with one cup of water (no more) and about a cup of ice tastes like a milk shake when made in a blender. I love this diet bettter than any other. Ive yo yo my whole life...not huge gains and losses just enough to go up a few sizes and not allow any clothes to fit and feel badly. SO, Im a believer....in the shakes only. I do exercise....try for one hour.....and started lifiting weights....and even try to walk atleast 25 miles a week. YOu need to attack the weight if you are a woman and over 50 .

My wife and I went on the diet May first, We have lost 30 lbs each. we average a half a pound a day. We only weigh in once a week.
We had a slowdown and our coach had us cut back on the bars and drink shakes instead. worked great. I am done losing and actually had to gain some back. My wife has 10 more pounds togo. As far as the food, find what stuff you like and return what you dont, the return policy is great, We actually spend less per month on food than when we where FAT. If you wanna get the most out of this diet, GET A COACH.

The soups and oatmeal are totally Disgusting, I gagged the first day. The shakes and meal bars are ok. I absolutely HATE this diet but i HATE being overweight even more so im hoping to lose at least 20 lbs this month and transition because i cannot last too much longer on this horrible food!!!! GOOD LUCK TO EVERYONE!!

Been on the diet since mid May of this year. Food sucks but I found the stuff I like and that's what I eat. Don't care for the soups and puddings. Shakes are good and cheese puffs are my weakness. As of this morning I a down 32lbs, with no exercise at all. I broke my foot after 1 week on plan. So I lost the weight sitting on my but. Have another 30lbs to go and another month at least wwith no exercise. Also got off 2 of my diabetes meds including insulin and BP meds cut in half. Dr. may take me off more meds after next visit. I didn't go to a clinic but dr. monitors blood levels A1C went from a 10.8 to a 7.7 in three months. It definatly works.

posted Jul 20th, 2011 3:40 pm


I started this diet on Tuesday, I am on my 4th day. So far I have found most of the food uneatable. It gives me so much gas I am afraid to leave the house. I went to one of the clinics but decided not to join that because it was very expensive. I only want to lose 20 pounds and it would have cost me about $53 dollars per pound if I lost it in the first 4 wks. I bought 4wk worth of food from them and am sorry I did because they don't have an exchange or return policy so I am stuck with a lot of food that I can not eat. The only things I found tolarable were the soup if you doctored it up the bars and some of the shakes. I think I could do just as well on Weight Watchers. I think any diet the limits you to 800 calories a day you can loose weight on. I am not sure how long I can stand this but I am still trying.

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.

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.
