Medifast Reviews, Both Good & Bad: Does It Really Work? 2018

medifast logoWhat we learned from Medifast reviews: Medifast is a popular meal-delivery program that’s high in protein and low in carbs and calories. It once again made the list of the Top 10 Commercial Diets and promises fast weight loss and diabetes control. But, does it really deliver?

Let’s take a look at how Medifast works as well as the many reviews and ratings of the diet to determine whether it’s a good option for you. (If it is, we have todays best coupons here!new)


The Medifast diet was first developed by a doctor over 30 years ago, and has been recommended by thousands of other doctors since. On their site, they say, “We are passionate about offering hope to those who yearn to be healthy but haven’t found the way.”

So, how does it work?

The foundation of this diet is the prepared Medifast meals that are delivered monthly to your door. These meals are low in calories and carbs, but high in protein, fiber, and key nutrients. While on the Medifast diet you’ll eat smaller meals every 2-3 hours including their shakes, bars, and “just add water” food that you supplement with 1-2 “Lean & Green” meals each day that are high in protein and low in fat.

The idea is that through calorie and carb-restriction your body learns to start burning fat instead of carbs, resulting in a sustainable weight loss of 1-2+ pounds per week. The low-glycemic carbs in the food also helps to regulate your blood sugar and metabolism, and make you feel full longer. This also makes the diet popular with people who have Type 2 Diabetes.

Medifast offers two plan options:

  1. The “GO!” plan offers faster weight loss and only 1 real “Lean & Green” meal per day
  2. The “FLEX” plan is more flexible, and offers more gradual weight loss, incorporating 2  real meals each day

*Learn more about these two plan options, plus how Medifast works.

The cost of Medifast is about $10-12 per day depending on which plan you choose, and which promotion you signup with. Here’s their best promotion for new customers:

So, does it really work? Scouring through hundreds of ratings and customer reviews online we were able to find some common themes. Let’s look at both the good and bad reviews, and learn whether it’s a good option for you.

Medifast: Bad Reviews

thumbs down

Sometimes the negative reviews for a diet or weight loss program are the most interesting and helpful. Why did it fail? Why do half the people on the diet eventually quit?

Here are the top 3 complaints from bad customer reviews:

  1. Doesn’t Work Long-Term: Medifast scores relatively low for “long-term weight loss,” getting a score of 2.1/5 from U.S. News
  2. Not enough “real” food: Most Medifast meals are shakes, bars, or just-add-water. Some users end up quitting because they don’t like the taste of the food and miss eating more conventional meals
  3. Too expensive: With a cost of up to $20 per day, the price is relatively high.

Many people turn to Medifast for fast weight loss. While it usually delivers, reviews support the idea that people often tire of the structured menu and yearn for real food again. Others quit after reaching their goal weight, but may gain the weight back after returning to old eating habits.

Other things that customers complain about in reviews is that there isn’t enough variety on the menu, and that you are encouraged to not drink alcohol. With this diet you have to be willing to give up menu freedom for fast weight loss, or it won’t be effective or enjoyable.

Customer review“Although I’ve lost 15 pounds, sometimes I miss the taste of ‘real’ food at certain meals.” Missy W. Durango, CO

Customer review:  “If I want to just drop 30 lbs on a diet, then it’s good to do Medifast. But as far as being on it long term and maintenance, I do not think it’s very good.” – Edna, Memphis, TN

However, most reviews for Medifast are positive, including those on Consumer Affairs, so let’s look at what people like about it.

Medifast: Good Reviews

review goodThe world of commercial diets is highly-competitive, so Medifast must be doing something right to still be in the game after 30+ years. Medifast can also boast recommendations from over 20,000 doctors during that time, and a consistent ranking in the top 10 commercial diets. Let’s look at the best qualities of the diet:

  1. Fast initial weight loss: Medifast’s biggest strength is quick weight loss, and it is ranked #3 in “Best Fast Weight Loss Diets” by U.S News & World Report
  2. Nutritious: The original goal of this diet was to create the elusive quality of being low in calories but high in nutrients, which they seem to have achieved
  3. Structured & Simple: If you follow the Medifast Plan, the math says that you are going to lose weight. Customers like the fact that there’s counting of carbs, calories, or points making it a good potential choice for the 50% of people who say they “hate to cook”
  4. Other Diets Didn’t Work: Medifast is a popular diet choice for certain people, including obese and diabetics, who have already tried other diets unsuccessfully and become frustrated. This is not a fad diet or a “lose 10 pounds for a wedding” weight loss program. Medifast offers hope for people who yearn to live a healthy lifestyle, and are willing to accept menu limitations to bring order to back their lives. In fact, Rod Tidwell (Jerry Maguire) Might say that people trying Medifast, “have been to the puppet shows, and have seen the strings.”

A number of customer reviews also mentioned enjoying the support and encouragement they got from others in the Medifast Community online, and from the helpful customer support. Several reviewers mentioned that the convenience of tracking meals and exercise through their FitBit was a plus.

Customer review: “I did exactly what they said to do and in the course of about three and a half months, I lost 53 pounds.” – Jeff, Clive IA

Customer Review: “I lost 50 pounds and my husband lost 90. So, it was very good. But lately, I was out of control. In order for Medifast to work, it’s helpful to make losing weight the most important thing, and it should take priority over everything.” – Milena, Rampa, Fl

Need inspiration? Here’s one of a number of positive and seemingly honest customer testimonials that you can find online:

You can see more testimonials on their site, and find a lot of positive quotes in online reviews:

Customer Ratings:

So, how do users rate Medifast? On customers were asked to rate their overall satisfaction” of the diet. Here’s how they rated the program:

Does Medifast Work? Customer satisfaction ratings

  • Positive ratings: 82% (4-5 stars)
  • Neutral ratings: 11% (3 stars)
  • Negative ratings: 7% (1-2 stars)

So, in effect when these customers were asked whether Medifast works, 82% said, “yes,” and were satisfied. The other 19% had a tepid or negative experience, often complaining that Medifast doesn’t work long term.

These unsolicited reviews seem to support the claims on the Medifast website that more than 3 out of 4 customers said it was effective,” and that “8 out of 10 customers surveyed said the Medifast Plan fit their lifestyle.”

Medifast Food Reviews

Medifast doesn’t score highly for their food, and you might just call it “adequate.” Most Medifast Meals are shakes, bars, and “just add water” meals that fall far short of a meal from the Olive Garden. But, then again, at 1900 calories, the Olive Garden’s Fettuccine Alfredo might be the reason you’re here in the first place!

Anyway, while their packaged food is uninspiring, the daily “lean & green” meal(s) are your only chance to eat something special.

*Metaphor alert: Think of it this way: You’re going on a journey, like someone who plans to scale a mountain. It’s not easy, so you need good gear and a map, and you know the food won’t be great. However, the view from the summit is worth the effort. That’s what Medifast is like.

Food Nutrition:

Medifast meals are low in calories (1000 per day) and carbs (85g per day). These meals are high in protein and fortified with 24 vitamins and minerals so that you can lose weight without losing out on nutrition.

These Medifast meals are also similar in nutritional content which means that you can substitute meals at any time without concern for your daily nutrition.

Every Medifast meal and snack lists Nutritional info and ingredients:

This is especially helpful if you have any allergies or want to know the exact amount of carbs, protein, fiber, sodium, or fat.

Medifast food is low in carbs and each day you’ll consume about 50g fewer carbs than the FDA’s recommended amount. This will help to curb cravings and teach your body to burn fat for energy instead of carbs.

So, Does Medifast Really Work?

medifast reviews

In order to answer the question of whether Medifast works, let’s consult both studies and customer reviews.

Medifast’s website states that “Medifast is safe and effective to do on your own whether you want to lose 15 or 120 or more pounds,” but add that:

“The average weight loss for Medifast customers on the “Go” plan is 11 pounds over 8 weeks”

Our Rating:

medifast logoHere’s how we scored Jenny Craig (1-5) based on these key areas:

  • Easy to Follow: 3.7
  • Nutrition: 4.2
  • Short-Term Weight Loss: 4.0
  • Long-Term Weight Loss: 2.9
  • Cost: 3.1
  • Overall Rating: 3.7

As you can see, we believe that Medifast works best for short-term weight loss, but doesn’t get a great rating for long-term weight loss.

Medical Studies

Now let’s look at independent studies to determine whether Medifast works. Studies and clinical trials notoriously stop short of publishing success rates or actually concluding that any diet truly “does work,” but here’s what they said:

1.) A 2015 study by Johns Hopkins Medicine found that: “Participants in low-calorie meal programs, such as Medifast, lost more weight than nonparticipants in trials lasting 4-6 months.” 

2.) Another positive review came from, which concluded that: “In obese adults, a meal replacement diet resulted in significantly greater reductions in body weight and fat compared with a food-based diet for 1 year after randomization.”

3.) The International Journal of Obesity compared Medifast to a conventional food-based diet of similar calories. They found that, “Medifast resulted in significantly greater reductions in body weight and fat after 1 year.” study

4.) Medifast Reviews from Mayo Clinic – The Mayo Clinic lists Medifast among its “meal replacement” diet options but notes that with all meal-delivery programs you have to make healthy choices for nutritional balance. (The Mayo Clinic also offers their own highly-rated diet, too) 

Ok, thanks for the generic answers! It seems the best way to answer the question of whether Medifast works is to consult the wisdom of the masses by looking over the scores of customer reviews online.

In Summary:

medifast logoThe Medifast diet is not for everyone. The weight loss program scores highly in expert ratings and and user reviews for “quick weight loss” but lower for “long-term weight loss.” This may be because of the nature of the diet which relies on prepackaged “meals” that are mostly shakes, bars, or food that you add water to.

With Medifast you’ll only have 1-2 “real” meals a day, and even those “lean and green” meals have to meet specific high-protein, low-carb guidelines.

If cooking or eating “real food” with few limitations is important to you, then Medifast might not be a good fit. However, if fast weight loss and structure are most important, then it’s worth considering.

Thinking of trying Medifast? Like we said, the diet has it’s strengths and weaknesses, but works for the majority of people.

  1. joanna

    I think the biggest takeaway from these reviews, (and my own experience) is that it’s a good diet for quick weight loss, BUT it’s hard to stay disciplined after a couple of months. I went on Medifast to lose weight for a wedding, and it was great. But then I craved regular meals, and quit after about 3 months. Now I’m on WW, which is fine for everyday use.

  2. Eliza C.

    Medifast worked for me. I am a diabetic who needed to lose 50 pounds, so I was done with trying these cheap diets on my own. Did the “Go” plan for 5 months which makes you lose weight faster. My one complaint is that I missed eating real food and drinking wine, but it was worth it to lose that much weight and get my blood sugar / eating in order.

  3. Milena

    I did exactly what Medifast said to do, and in 4 months I lost 53 pounds. My eating / food cravings were out of control, so I like the structured plan. The food isn’t the best, but Medifast works you if you make losing weight your top priority.
