No joke – over 50% of diet products simply don’t work. So what about Medifast? Here at DietSpotlight, we decided to conduct an in-depth review, closely examining the product’s side effects, ingredients, customer service quality and scientific studies. Plus we scrutinized hundreds of user comments, which are posted all over the internet. Lastly, we summarized all the facts and details to give you the bottom line.

Medifast Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What is Medifast?

To start off, Medifast is a weight-loss program that was founded by Dr. William Vitale. You are expected to eat specific food portions. Meals are delivered to your home on a regular basis. The menu consists of soups, entrees, bars, sides, shakes and high-protein foods. According to the official website, there are three primary plans available, which are the Achieve Weight Loss Plan, Thrive Healthy Living Plan and Medifast for Special Diets. Each day you can have four meals, one healthy snack and two lean and green meals. There are more than 70 different choices to select from. [1]

Medifast has been around since 1980 and everything can be purchased directly from the main website. There are customer testimonials posted on the website, as well as a 30-day money-back guarantee, but read on…

Steep Price – “Something to Consider?”

The first concern we had was with the price. “The actual cost of the Medifast weight-loss plan is $300 to $400 per month, which many people simply can’t afford. There is also the cost of shipping,” says our Research Editor.

One dieter stated, “They make it difficult to login or change your password, so I got a notice that I was billed $350 for a reshipment at midnight last night and immediately reached out to support to stop the order. They claim they cannot stop an order once it is placed which is nonsense as it won’t ship for days.” [2]

According to another customer, “I am so outraged and devastated. For two years I watched everything that went in my mouth and going back on Medifast for 2 weeks and spending $400, I gained 7lbs.”

To save money, some dieters go to Amazon.

One review said, “I save over $100 per month by ordering from PSG.” [3]

Medifast Customer Testimonials

Consumer Complaints about Medifast – “Another Concern”

We found all sorts of user complaints across the web on several Medifast reviews. In fact, one dieter commented, “Horrible customer service and shoddy business. Stealing money is their only objective.”

Another user said, “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.”

Happy customers are out there, too.

“I have been following medifast program for 11weeks now and my results are pretty great,” claimed one dieter. [4]

Our research has revealed that if there is one particular aspect of a diet program or supplement that is very troublesome (a painful/difficult exercise routine, steep price, customer complaints) the probability of long-term success is low. Therefore, if Medifast is not acceptable to consumers, this could be a serious problem.

What About the Science?

Some Medifast reviews and clinical studies are mentioned on their website, but from what we gathered, these do not prove it will be effective for you. It really just depends on the individual and his or her weight-loss goals. The truth is, reducing your daily caloric intake may give you similar results and this doesn’t cost as much money. At DietSpotlight, we prefer to see solid science that supports the diet program we’re reviewing.

The Bottom Line – Does Medifast Work?

Now the moment you’ve been waiting for – our bottom line on Medifast. Well, we like the longevity as a diet program and some positive comments we saw about it online. However, we are concerned about the high cost. Also, we are leery because of all the customer complaints we found online. [5]

If you’d like to shed some serious pounds, we encourage you to go with a diet program or supplement that does not cost you a fortune, is backed by plenty of positive customer reviews and is easy to use anywhere.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement contains four potent ingredients, which have been tested and shown to help accelerate metabolism, improve fat loss and curb appetite. We can’t find any discussion of harmful side effects and user comments around the web reveal people are seeing solid results.

The makers of Dietspotlight Burn are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

What You Should Know about Medifast

Medifast is basically a diet plan, which consists of pre-planned meals, similar to Nutrisystem. There is a separate Medifast "5 in 1" plan to suit women, men and individuals afflicted with diabetes. The official Medifast website states that this diet program does not involve the process of counting calories or points. The meals involved with Medifast are stated to be low in fat and calories, but also nutritionally rich. A single month's supply of meals costs $275, regardless of whether it's for men or women. Consumers additionally have the option of designing a more specific menu of meals.

The official Medifast website claims that each meal is "portion controlled" and user's tend to see results in the first week. The individual meals are stated to "create a calorie deficit," hence enabling the body to burn off fat as energy. Medifast supposedly enhances lean muscle mass by offering just the right combination of carbohydrates and protein. When it comes right down to it, Slim Fast has a weight loss plan that focuses on curbing appetite and keep blood glucose level between meals. There doesn't appear to be any key active ingredients found in Medifast meals other than simple nutrients. The general cost for using the Medifast diet program is 10 dollars per day. Medifast meals incorporate a vast array of fruit drinks, bars, chili, soups, oatmeal, hot beverages, shakes, puddings and eggs. The official Medifast website lists no side effects in regards to their meal plans or products. Medifast meals are intended to be eaten every 2-3 hours, which is commonly six times each day. If all meals are not consumed, it's claimed that the weight loss process can be hindered or slowed down due to the user's body storing energy. When diet plans are combined with exercises like Piyo they, at times, aid in weight loss results.

Product Features of Medifast

Medifast is a diet plan consisting of pre-planned meals. This product comes in three forms; one suitable for women, one for men and one for individuals that suffer from diabetes. While Medifast does not appear to contain any specific key components, it is stated to offer a sufficient variety of protein, carbs and nutrients. This combination is claimed to assist users in reducing weight and acquiring lean muscle mass. Medifast aims to "create a calorie deficit," hence enabling the body to burn off fat as energy. The general meal plan costs $275 per month and users are directed to consume six meals throughout each day.

Advantages of Medifast

  • Medifast can be conveniently ordered online through the official website.
  • There are Medifast meal plans specifically geared toward women, men and diabetics.
  • The Medifast diet program does not involve taking medications.
  • The official Medifast website offers consumer success stories.

Disadvantages of Medifast

  • Medifast may prove to be a bit pricey for some consumers considering it costs $275 per month.
  • The Medifast eating program may be difficult for some individuals to keep up with since it involves eating six meals each day.
  • Some dieters may find the Medifast plan somewhat restricting since they're only able to consume the Medifast meals.
  • Medifast meals have to be eaten every 2-3 hours, which may not fit every dieter's schedule.
  • Some individuals become "bored" with the meals and even find some unappetizing. (See reader comments.)
  • Medifast does not appear to contain any specific active ingredients that curb hunger or promote fat reduction.


While some individuals may enjoy the idea of Medifast providing all daily meals, the plan itself might get a bit pricey over time considering it costs $275 per month. On the bright side, Medifast does not involve any diet drugs or pills. However, the idea of consuming six meals each day on a schedule may be somewhat difficult for working individuals, or for those with frequently eat out. It's prudent to examine all current diet pills and plans prior to purchasing one like Medifast. Especially since this program restricts the consumption of foods that are not purchased from Medifast.

Medifast is a weight-loss program based on purchasing prepared meals and snacks. This is a clincally proven means of reducing caloric intake for weight-loss, if the dieter sticks with it. The three plans available are: Medifast Achieve Weight Loss Plan, Thrive Healthy Living Plan and Medifast for Special Diets.

We took the time to really dig deep into the Medifast ingredients so we could give you all of the important facts.

Soy Protein

Soy protein[1] is derived from soybeans. It is an alternative to animal-based proteins, and is commonly found in supplement powders, shakes and bars. Furthermore, it’s basically free of saturated fat and cholesterol. It’s also low in calories and provides phytoestrogens.

What is it Supposed to Do?

Soy protein is often used in meal-replacement products, fitness shakes and diet snacks to aid with weight-loss. It provides protein and amino acids[2], which help promote muscle growth. This ingredient may also reduce hunger and help with heart health.

Clinical Research

According to the University of Maryland Medical Center, “Studies suggest that soy protein may reduce the risk of heart disease by lowering levels of LDL (bad) cholesterol. For example, in a clinical study of nearly 5,000 men and women living in Japan, those who ate the most soy had the lowest cholesterol levels.”

Whey Protein

Whey protein is basically a byproduct of cheese manufacturing. It is often used in supplement powders and shakes. This protein is available in forms such as concentrate, isolate, and hydrolysate. It provides amino acids, which are the building blocks of protein.

What is it Supposed to Do?

Often whey protein is used in fitness shakes and diet products to help with muscle building, fat reduction, increased energy levels and reducing appetite. When consumed in place of foods high in fat and sugar, this ingredient may aid with weight reduction.

Clinical Research

“Whey protein supplements may not be your favorite weight-loss aid, but they can help you lose fat instead of muscle, according to a 2008 study published in Nutrition Journal. This study found that a whey protein meal-replacement shake helped a group of overweight and obese individuals following a reduced-calorie diet lose more body fat than muscle.”

Nonfat Dry Milk

Nonfat dry milk is a dairy product that is created from real milk. The water and cream are essentially removed. It still provides vitamins, minerals, calcium and protein. However, it does not have the same level of fat and cholesterol you find in regular milk.

What is it Supposed to Do?

Nonfat dry milk is commonly used in recipes, protein shakes, diet products and various processed foods. It is often used in place of regular milk when required.

Clinical Research

NCBI.gov reported that, “Mice fed nonfat dry milk had less body fat and reduced mRNA markers of adipose inflammation (p < 0.05) than CONTROL mice despite greater cumulative energy intake.”

One that’s caught our attention is one called Dietspotlight Burn. There’s solid science supporting the clinicially-tested ingredients. Want to learn more? Click above.

Medifast Side Effects:

Soy Protein

Dietary soy protein had reduced fat mass body weight in obese humans, as well as decreasing plasma lipids. There is an array of mechanisms in which soy protein improves insulin resistance as well as reducing body fat and blood lipids. Intake of soy protein has the ability to trigger an allergic reaction, (like most protein) and should be avoided in individuals who are at higher risk of food allergies. Long-term trials including many obese participants are required to confirm whether soy protein delivers long-term safety as well as benefits in obese humans. [1]


Fructose inside high fructose corn syrup, as well as sugar, creates sweetness in beverages. This sweetness could be the cause of obesity in relation to soft drink consumption. Fructose intake has been linked to the metabolic syndrome as well as irregular lipid patterns. This data indicates that there needs to be a concern for amount of fructose intake, which has risen over the past 200 years and now is responsible for 10% of energy consumption of some individuals. [2]

Whey Protein

Prolibra (specialized whey fraction) participants had lost substantially more body fat in comparison to control participants in both the completer (2.81 vs. 1.62 kg P = 0.03) as well as the responder (3.63 vs. 2.11 kg, P = 0.01) groups. Participants taking Prolibra had lost substantially less lean muscle mass within the responder group (1.07 vs. 2.41 kg, P = 0.02). Fat to lean loss ratio had been much larger (kg fat lost/kg lean lost) for Prolibra participants for both completer (3.75 vs. 1.05) as well as responder (3.39 vs. 0.88) subject groups. In a 500 calorie reduced diet, participants in both the control and treatment groups had experienced significant weight-loss. Participants administered Prolibra had lost substantially more body fat and displayed a greater preservation of lean muscle in comparison with those ingesting the control drink. Because the participants ingesting Prolibra had lost 6.1% of their body fat, and because participants had experienced a 5% decrease of body fat which has been shown to decrease risks of obesity and related diseases, the data has practical significance.[3]

Non Fat Dry Milk

Mice that were fed non fat dry milk had experienced less body fat and had decreased mRNA markers of adipose inflammation (p < 0.05) than control. In addition, mice fed non fat dry milk had lipid mediator profiles that were distinct from control as well as HighCa mice. Non fat dry milk mice had displayed increased plasma monoacylglycerols (6 – 46% increase from control mice), including reduced fatty acid diols and 2-arachidonoylglycerol. The alterations in the specific plasma lipid mediator profiles had reflected on the inflammatory and metabolic phenotypes as seen in non fat dry milk feeding. [4]

Stephen Wolf

Can you drink alcohol while on Medifast. I do like to have my beer at night?

Victoria (Editor)

Hello Stephen, it is recommended that you not drink alcohol. Unfortunately, those extra calories add up to extra pounds on the scale and can cause weight gain.

  Going to start the product.

Montana (Editor)

  Dietitian or counselor

Does anyone know how much a dietician or COUNSELOR at Medifast, etc…gets paid? I am looking to get into this field.

Victoria (Editor)

Hello, it depends on the desired position and level of experience. The available positions at Medifast include are Clinical Nutrition Director, Corporate Dietitian and Dietetic Technician with Nutrition Support.

Meghan Sue

Can I have a couple of glasses (not more) of red or white wine in the evening?


You are not supposed to drink while on the plan because there is so much sugar in alcohol that it can hinder your weight loss.

Victoria (Editor)

Hello Meghan, it is recommended that you do not consume alcohol due to the high caloric content, that will hamper your weight loss.

  What's the ingredients.

I’m considering trying Medifast. Are there nuts in the bars or any of the food? I am very allergic.
Also, how long do you have to stay on maintenance?

Maribel (Editor)

Hello Patti, one of their bars contain nuts: Peanut Butter Crunch Bar and some of their dinner recipes contain pine nuts. Medifast suggests the 30-Day Medifast Go™ Select Kit to see results and for maintenance they encourage continued use to prevent gaining the weight lost, a suggestion is 2-3 Medifast meals per day.

  diet plan

Hello is there a diet plan just using the medifast shakes?

Maribel (Editor)

Hello Donna, yes. You can buy a box that includes 7 or 24 shakes (the flavors are Dutch Chocolate, French Vanilla, Mocha, Orange Cream, Strawberry and Dark Chocolate). The price is either $19.50 or $66.75. However, if you’re looking for an effective way to lose weight, you might want to consider Dietspotlight Burn.

There’s definately a lot to know about this issue. I love all of the points you made.

Maribel (Editor)

Thanks! We’re so glad you enjoyed it. 🙂


I have been on medifast for about 17 weeks and have lost about 75 pounds, i am about 20 from my goal weight. I did have lots of bloating from the soy protein, but i have substituted 3 half servings of Gnc go lean 25 and and half serving of Nature”s Best Isopure low carb, i now just eat the mixed berry cereal from Medifast.. I don’t have all the bloating and gas anymore and my recent blood tests came back excellent and my blood pressure has gone from 200 over 110 to 115 over 72 and i had my medication reduced . I am grateful for Medifast because when i needed something fast to start losing weight , they were there. I cook now as i cook my lean and green meals and i have planned what replacement cereal and how many regular meals and protein powders i will take after i reach my goal . I will gradually raise my calories and i am probably not going to try any of their transition food. I do not go the center every week like i use to , i go now every two weeks.


Im really sorry! I wish i had read ur experience before getting started. I asked the questions about people with kidney problems. Ive been a stage 3 CKD for years now and recently was diagnosed with stage 4. Then a mass was found in my right kidney so after a partial removal my kidney function was stable at 24.5. So im finally able to return to work i started the program on leave and now my kidney function has dropped to 20.3. I wish the had been honest and told me so i could just follow my renal diet because i was doing better just not losing weight. At least i was healthier.

  Run away from this !
Angie (Verified User)

I started this diet last May. I lost 10 pounds my first month. The food is somewhat tolerable if you are getting results. Just so you all know, this is not real food. there are no labels on any of the packaging stating what the ingredients of each food item were. That in itself is alarming to me, but I was desperate the lose the weight. I chose this diet because it supposedly comes with a coach. they call you once a week and try to encourage you and help you through the rough spots of dieting. Then they start really wanting your resluts because ofcourse, it helps their business if you are successful… which then leads to “the business” part of medifast and take shape for Life. I came to realize that once I refused to work the business part of this diet, and being forced to do a three way call with her “Upline” coach, my scholarship for the program that helped me with the cost of my food went away! immediately… which then took it’s toll on my budget at almost $400.00 a month. Also, I was suddenly paying more, because the scholarship diet help went away ans so did my coaching. no more calls… WOW!~ this diet has lost it’s mission to being a money making business and if you are not on board, you pay the price… literally. Also, As soon as I weened myself off this program and started eating real food again, my weight came back at a steady pace… I am now back to being afraid to eat again… The diet program was not real food, my coach failed me because I was not interested in contributing to her business and I’m back up in my weight… Disapointng… go see a doctor, ask to see a nutritionist that can help you learn about real food and changing your habits… Yes, you have to pay for that too, but they are not trying to sell you a business filled with Soy and mystery ingrediants… Run away from this Takr shape for Life and medi-fast as they will empty your wallet and leave you hanging… run… as fgast as you can in the opposite direction… run!

Janet Hanauer

I totally agree with Angie-very well said.


This post makes no sense to me. Why do you think you should continue to get the scholarship if you’re not upholding your part of the deal?!?

  Worked Long term For Me
Stacy Phillips

I lost 150 pounds utilizing Take Shape For Life which is the Free Health Coach division of Medifast, Inc. and I’ve kept it off for over 2 years now. This is the only thing that ever worked long-term for me.


I’ve lost 50 pds and love the program


Stacey, I was ready to sign up tomorrow, but am scared when I hear about the hair loss, soy messing with my thyroid etc, terrible food etc… My coach is a doctor who lost 150 lbs… I’m really on the fence of what to do


Isagenix is a great, safe, effective system.


Yoli is a GREAT system, we eat REAL food! No package food with Yoli.


I just started Monday. It’s harder this time during detox. I’m tired, gassy, and have headaches. That usually stops after the first three days though. I lost 15 lbs in 30 days last time, but stopped bc I became pregnant.


Oh my gosh. After having read all the posts I am shocked at how many people are not recognizing a diet that is hurting their body! They are filled with reactions that are your body telling you it is out of balance. Losing hair??? OMG!!! Exercise, eat right and loss weight in a controlled manner that in the end does not need a maintenance diet nor going back on the program. Medifast is nothing more that a quick temporary fix based on starvation.


Agreed. I did the eat healthy and exercise. Lost the weight and a few sizes and it has now been 8 years. When you look for a short cut path, you get short term results.

Ben (Verified User)

I started 5 days ago at 272. My healthy army weight was 195. I am 53. I have lost 12 pounds so far. Granted I was once athletic but I have been eating poorly for years. My blood pressure was averaging 145 over 95 and as I take it every morning I am now at 118 over 23 – this morning! Ok the food can be bland but the olive oil or in my case since I steam everything in the
Microwave, I eat two tbsp of Baleans fish oil to stave off hunger or add a can of tuna in water and I can then deal with some discomfort.

Eating these packets is easy if you just set your phone alarm. Don’t wolf the food. Nibble at it, chew it, and then drink your 8 cups of water. I have don the military three day plan, southbeach, sugar busters and willpower to some success then a fail. This is a mindset and lifestyle change along with a healthy diet. You can have vitamins too. I take a Multi plus C Hawthorne biotin for hair E coQ10, potassium, calcium and magnesium and a medley of b vitamins. It is all good. Pancakes and Mac and cheese suck. All else is tie table to good. Btw I am a director of Foodservice for a food store chain

   I reached my goal weight with ease
Patrick (Verified User)

I was on Medifast a year ago for 10 weeks and lost 35lbs. I reached my goal weight with ease. It was easy to eat the 5 pre-planed meals and I’m a big fan of eating meat and veg so the one cooked meal a day was great. I went back to old habbits and gained all the weight back. This diet really works. I’m getting ready to start it up again but this time follow the mantenance plan after I lose my weight.

  it works if you follow the program.
Treasure (Verified User)

Well my 5-year old loves the bars, brownies and shakes. Can’t get him out of there. Medifast has helped me cut out bread and now I not bloated. Have not checked the scale…but i havr lost 2 sizes. Your stomach shrinks with the smaller portion sizes. I cheated one day and ate a banana. Got a bellyache—too much food.


If a banana is too much food, you have a problem.


It’s a problem I wish I had. We Americans struggle with portion sizes and most of us could (and should) adjust (reduce) them drastically!

  if i can use a sugar free coffee creamer on this diet?
jamie (Verified User)

i have been on the medifast diet for 10 days and ive lost 8 pounds so far. i have been having some tummy troubles though and am wondering if this is normal. I also would like to know if i can use a sugar free coffee creamer on this diet. coffe is my addiction. thanks!

Janet Hanauer

Loss the first week is water weight.

Victoria (Editor)

Hi Jamie, some clients experience different side effects. Please consult your physician to select the right product for you. Sugar free coffee creamer may be used with this diet.

  Unhappy with the results.
Heather (Verified User)

I have been on Medifast for two weeks. I wasn’t as hungry after about a week and a half, but I can’t get used to the awful food. I feel bloated,and light headed and have terrible gas and a headache mostly all day. I am used to eating mostly whole foods with some cheating here and there. I wanted to lose 15 lbs. before vacation and thought this would be a good idea. I am glad I only purchased one months worth of food. Will do weight watchers to get back on track in the future. This diet is just not sustainable.

  Too much price.
patti t (Verified User)

I just came back from a consultation & I need to lose 40/45 lbs. goal time is about first week in Aug. fine. Then I was hit with the total cost $1152.27 to join first 20 weeks food cost is $82.50/6 weeks cost of food 30/40.00. I find it extremely expensive & don’t know if I can afford it. Final cost about $3,000 ish. Can that be right? Thanks.


yes, I went with my husband to a consult to get started the start up cost was 1750.00 and that didn’t include food. go to gnc and buy there lean shakes in the 25 protein and cant remember carbs but less just like the medifast label. plus the lady almost held us hostage waiting for us to make a decision when we said we needed time to talk about spending that kind of money. her comments were you came here for a reason nothing will change tomorrow that isn’t the same as today ect… we know a man featured on one of there commercials he lost over 100lbs but when he was weaning off the program he hadn’t reported in for 4wks and they never called to check on him until the end of the 4th week he was mad he said your not calling to check on how i’m doing your calling to see when i’m coming in to spend more money, your just calling to see where the money is. of course they said oh no we care, they didn’t care before then only when his monthly money didn’t show up. and he barley got squat for doing the commercial. so even tho it worked for him, he is starting to see there clear purphase money. he said same thing you can research shakes and bars with about the same amount of carbs and protein. you want protein to be higher if possible on shakes and bars need to be close if carbs in a bar are15 protein needs to be 12 and up as close as u can get. good luck and please don’t give them money.

Victoria (Editor)

Hello Patti, the consultants will always evaluate your needs and provide you with a quote according your goal. It is suggested that you compare with other weight loss programs to make a decision that is right for you.

  Not so happy with it.
Renee (Verified User)

I think people may need to hold on to their receipts. I have Quicken so I know exactly how much I spend monthly on food. Last year groceries and eating out totaled $5059.00. On Medifast it would have cost $3000.00. Just some food for thought.


Not everyone buys expensive food and eats out a lot. I wouldn’t even come close to hitting $3K, let alone surpass it. And the food I choose actually tastes good.

  Works well with my medications
rhonda anderson (Verified User)

i have type 2 diabetes i order the diabetes meals… i’ve been on this diet 4 wks now i’ve lost 20 lbs and been off my 4 diabetes meds i was taking every day to taking none after less than 2 weeks….. amazing my diabetes averaged 240 even with the meds and now stays around 105 🙂

  Product is not good for me
Mary (Verified User)

Medifast i lost so much hair and only after a 6 weeks. It was coming out by the hand fulls. If you have regular or thin hair run!! If you look on their site where all the customers chat there are PAGES of posts about hair loss on medifast – and bald spots. I wonder what else it was doing to my body that i couldnt see.


I too have lost a lot of hair!!!! Thankfully I have thick hair, but I can really notice how thin it has gotten all over. I don’t blow dry it or straighten it anymore. I would never had done this diet if I had know I would lose this much hair or any hair at all. Hair loss is still continuing and no new hair is growing!!!!! Better think twice about this diet

  Too bad I like it!

really liked medifsat but I was postmenopausal for 2 years and after 3 months I got my period again!! First I noticed breast tenderness and I felt like I was going to get a period and then I DID! I went tomy gynecologist and had to have a cerviacl biopsy luckily it is benign but the soy was acting like estrogen for me. Too bad i like it!

  Medifast food sucks

alot of the food on medifast really sucks. the oatmeal and the softbake cookie are horrible. the rest is tolerable. If they improved the taste it would be much better.


I love the soft bakes maybe they have improved them but I love this program. I am not hungry and I go yo bed with a night time cookie!

I am currently on the plan and have been for almost 5 weeks now. I have lost 19 lbs (only 1 last week) We (my husband and I are both on the diet) are very strict and don’t cheat. I don’t feel energized, I feel nauseated, dizzy when I stand up, even like I am going to black out sometimes. I feel fatigued and have headaches. I have not had a menstrual cycle except for slight bleeding after being intimate. A little concerned. I take thyroid meds for hypo. Any suggestions?

Hi, losing weight rapidly may cause estrogen levels to increase in bloodstream, which can have an affect in menstrual cycle. Also, the most common side-effects users have mentioned are upset stomach, nausea and headache. Please see your Ob-Gyn or Physician if your side effects persists.


If u have hypothyroidism, all the soy in the medifast products counteract your meds. Take your meds in the middle of the night. Set an alarm. Trust me, it helps.

I’m having stomach problems and diarrhea. I think it is from the maltitol syrup in the bars. Any suggestions other than eliminating the bars?


Eat healthy, exercise and get off a diet that is causing you medical issues? just a thought….

Hello Linda, all dieters have different weight loss results. Upset stomach, nausea, headache and irregular bowel movement are the most common side-effects users experience. Start with eliminating the bars and see how it goes. If you continue to have these effects, please consult with your physician before continuing to take Medifast. Good luck!

Clearly, your oncologist is NOT keeping up with the latest, and/or does not know how to use PubMed to keep up with recent studies. If she did, she’d read otherwise. Soy can safely be eaten by breast ca pts; it does NOT increase breast tissue density, isoflavones may in fact decrease tumors by competing with natural estrogen (which is much, much stronger than isoflavones), and may prevent recurrent of breast ca. The only contraindication to soy is if the pt is taking tamoxifen concurrently–in which case, soy may decrease it’s effectiveness. Otherwise, according to RECENT STUDIES, it’s okay, possibly beneficial to eat when eaten with a balanced diet of other proteins, vegetables, fruits, and limited grains. Not every dr is keeping up to date or graduated anywhere near the top of his/her class, so don’t assume so. Get another opinion.

  Want to know if anyone experience this?

Here is my problem (maybe someone experienced something similar). First day I started Medifast I didn’t mind taste it was ok with a little light spices added. But after second meal I started to feel very dizzy (almost felt of my chair) and my heart rate went crazy, I also had some weired feeling in my stomach and my hands and legs got cold and kind of numb. I also was shaking and breathing heavy. I basically had to take right away a mint with glucose that I had on my desk by chance and drink a bottle of water so I don’t pass out. Later at the day I got diarrhea. I called medifast they told me it was because of low calorie intake, but I been on calories count for a while and by that time of the day that was the same amount of calories I usually intake without this side effects. So I had to eat a fruit after that experience because I thought maybe my sugar dropped. After water, fruit and mints I felt better… till the next Medifast meal I eat, which again made me dizzy and my hands numb – so I don’t think it is low calorie intake. I also don’t feel hungry after taking this, but I also lost a taste, anything I try seems tasteless. I want to know if anyone else had similar side effects and what ingredient may cause it?

Hi Lilly. Medifast suggest having their soup or bouillon if dizziness, lightheadedness, or tiredness persists. Also, to drink plenty of water (at least 64-ounces). Your symptoms may have resulted from the fact that you most likely entered the fat-burning stage. However, these symptoms shouldn’t last more than a week, and if they do, please make sure you contact your physician immediately.

  Product is expensive cannot afford

I cannot afford the $1500.00 it costs to join so the Medifast counselor offered me a much cheaper rate but w/no counseling. Do I really need it to be successful on this plan esp. on the maintenance plan? Will I know how to eat properly and maintain my weight w/o the counseling?


hi i don’t understand why it’s will cost you that much money. that’s total wrong. and the counselor is free for rest of your life. my coach i never here from her. me and my sister we supported each other. my coach she cheated and gain weight. and now back on medifast. i think it’s kinda funny when i cheat i cheat eating fruit. like strawberrys grapes. blueberrys. i love fruit. but i don’t understand so many people on you tube have lost so much weight not doing medifast just eating fruit salads. i love salads. and fruit but when i ate fruit while on medifast weight lost stop and gain weight.

Hi Tracy, the counseling is an additional component of the Medifast plan, that guides and supports you along the way to achieving your diet goals.
