When you make the decision to start on a weight loss journey by dieting with Medifast, the popular meal replacement, doctor approved home delivery diet program, you quite probably have made the best decision of your life! The posts and pages in this section of the website are here to help you turn a plan into an action plan for a slimmer, fitter and healthier you!

Let’s take a closer look at this amazing way of eating that makes it possible to lose the excess pounds easily and without any hassle.

What’s So Special About Medifast?

It is highly appealing to anyone who leads a particularly busy lifestyle that wants to lose weight but struggles with finding the time to work on a more traditional style of diet. That’s the kind with diet sheets, ingredient chart, calorie calculations, weighing and measuring and all the other hassles that come with that way of dieting.

It is all time consuming and means having to go to the store to buy the food ingredients, then prepare and cook meals that must conform to the strict regimen that your dietitian has prepared for you. Sure, you will lose weight this way, but if you don’t have the time for it all, it won’t do you a whole load of good if you can’t stick to it.

What Makes Medifast Different?

This is a special dieting system that provides all the food you need to eat delivered to your home packaged in individual meal packs to make it simple and straight forward. It’s fast and convenient because all the food prep and calorie calculating has been done for you.

All you do is heat up the meals in a microwave oven and eat. Fast, simple and best of all, it works!

As long as you stick to the program and do not deviate by cheating on high calorie snacks or sodas, you will lose weight. Pure and simple!


When you crave something sweet, snack on low-glycemic fruit. Foods with a low GI have a glycemic index of 55 or less. Fruits with a GI of 55 or lower include cherries, grapefruit, oranges, apples, peaches, pears, plums, strawberries, grapes, mango and bananas.
While on this plan, try to eat mostly lean meats, nonstarchy vegetables and low-glycemic fruits. If you must deviate from this and have a treat, choose options like sugar-free gelatin and pudding, as well as packaged 100-calorie snacks. Save these as an occasional treat so that you don’t compromise your weight loss.

Limitations: You’ll mostly eat meal replacements. There is some variety: Medifast has more than 70 meal replacement options including shakes, bars, cereals, and snacks like pretzel sticks. Fruit, dairy products, and starches aren’t allowed in the 5 & 1 Plan.
This plan is about sustaining your efforts in weight loss. Have you already lost 10, 20, or 30 pounds? Keep up the good work, and now maintain it with the proper diet. Once you reach your weight loss goals, you acknowledge it, reward yourself and find a routine you can then live with to sustain it.
A 2017 study sponsored by Medifast found that more than 70 percent of overweight adults who were put on Medifast and received one-on-one behavioral support lost more than 5 percent of their body weight by their final visit (anywhere from four to 24 weeks later).
But, the problem with any weight loss plan is that people tend to regain those lost pounds once they stop the diet because they simply return to their old eating habits which made them gain weight in the first place.
While each clinic is a little different, typically a weight management team will include a physician who provides regular monitoring of health status, a dietitian who provides nutritional support, and a behaviorist who leads weekly sessions on various lifestyle topics.
They note that some shakes are sources of unhealthy trans fats, but that most Medifast meals are protein-heavy, from “soy protein isolate, milk protein isolate and egg whites.” They also note that some products get their carbs from “wheat flour, although other products are gluten-free for people who are sensitive to gluten, a protein in wheat. Sugars in Medifast include corn syrup and fructose. Inulin and gum arabic are ingredients that add dietary fiber.”
I have been on it since November 1st, and have lost 58 lbs…average a safe 2 lbs per week. It is perfect for my lifestyle, as I never ate much during the day prior to the diet. Now my routine is their oatmeal for breakfast (I add cinnamon and Splenda), two protein shakes (I add one Splenda to each), and two protein bars a day…that’s my 5 Medifast “meals” then I eat one sensible low cal/low fat meal..sometimes I eat it at lunchtime and sometimes dinner. I sometimes have their soup instead of one of the shakes or protein bars. It has absolutely worked for me. I found the food in the program that I like and I order that, I am motivated, and I have been happy with the slow consistent week after week loss.
Congrats to everyone one the medifast plan. I too was on it in 08 and lost 30lbs. due to the fact of my own fault simply giving in to sweets like cheesecake and cholcolate I gained it back, but today I just started again with the weight of 298. I know it is hard, but you feel so good when u drop a couple sizes and feel thinner
A clinical study at the Johns Hopkins University showed that the Medifast diet results in substantial weight loss. When on the diet, adult men could shed, on average, 67 pounds; women can lose up to an average of 56.
Medifast has been something that I have used several times over the years, and much like Nutrisystem, these days I like to use it as a “reboot” if you will. Most of the time I am able to maintain a healthy weight, but there are times where I might slip up – like say around Thanksgiving and Christmas, for example – and when that happens I like to use meal delivery systems like Medifast to quickly lose the extra weight I packed on, and to get things back on track.
Eat six meals a day and still lose weight? Medifast calls it its “5 & 1 Plan.” If you eat five Medifast meal replacements and one meal that you provide, Medifast says you can lose 2-5 pounds during the first 2 weeks of the plan. People typically lose 1-2 pounds per week after that.
The Medifast diet promotes rapid and sustained weight loss. This very-low-calorie, low-glycemic eating plan features Medifast specially formulated, packaged, vitamin-packed meals. The key to weight loss on the diet is its very low calorie content as dieters on the program eat between 1,000 and 1,300 calories daily. If you prefer to create your own custom diet similar to Medifast, instead of purchasing Medifast meals, you’d follow a very-low-calorie, low-glycemic diet using foods from the grocery store.
The program is one of an increasing number of home-delivered diet programs. Such programs have surged in popularity in recent years. Although costly, research has shown there are benefits – mainly from having controlled portion sizes.
I was trying to lose weight so I used Medifast. I order online which is convenient in choosing what I want and I find the shipping cost too high so I try to avoid it. I’ve tried different things but the food becomes too boring after a while and I don’t feel like having it anymore. They use the bars and there are some meals that I thought tasted horrible. Also, there isn’t enough variety and it’s hard to keep eating that food. But it makes me feel full for a while and I lost some weight in the couple of weeks that I’ve tried it. Overall, my experience is good.
Dieters can rest assured that the Medifast diet plan is guaranteed to work. There is a 30-day money back guarantee, at the official Medifast site, they states that dieters that stick consistently to their program will lose weight and earn rewards. If after 30 days no weight is lost, the company will refund any money spent on products.
Depending on a dieters goals and specific needs, there are 4 different plans to choose from. First, there is the 5 & 1 weight loss program. This program is the most popular choice, and it consists of 6 separate meals each day, every 2 – 3 hours.
But a common theme I found was that a number of people, while giving it high marks as very effective for extreme weight loss, caution that it’s difficult at best to sustain it and many gain some or all of the weight back once they go off the diet.  This however applies to most diets unless you change your habits and make eating healthy and within the needed caloric range your lifestyle.

The bottom line is that Medifast has been shown to be effective for weight loss. Several studies cited above showed that people who stuck to their Medifast plan lost more weight than people who followed food-based plans. However, the key to any diet plan is to not only lose the weight but to keep it off. That part is completely up to you.
Medifast makes no claim that these results are representative of all participants on the Medifast Program. Medifast recommends you consult with a physician before starting a weight-loss program. Individual results will vary. Medifast is the brand recommended by more than 20,000 doctors since 1980. Typical weight loss on the Medifast 5 & 1 Plan® is 2-5 lbs per week for the first two weeks and 1-2 lbs per week thereafter.

Medifast is not about taking off a few pounds – it is intended for those who are very overweight. It is a drastic diet that will put you into state of ketosis, and you MUST ensure you are adequately hydrated.
A 2016 study supported in part by Medifast and published in the journal Obesity found that obese adults lost 8.8 percent of their body weight after 12 weeks on Medifast, and 12.1 percent of their body weight if they took phentermine, a weight-loss drug that can reduce food cravings, at the same time.
I love Medifast. When I was on it years ago, I had to get it from the doctor. I lost 60 pounds then I kept it off for 15 years. I gained some weight back so I figured I would go back on it. This time, I’ve been using it for seven weeks and I’ve lost 18 pounds. Another seven weeks more and I’m set to go on maintenance. I do the treadmill every day, so that helped make it come off faster. I used to do it the treadmill an hour but it’s low calorie so I just do half an hour now. I love the food. I don’t love everything, but I have my favorite. It’s the easiest diet ever because I’m not hungry. I do the 5 then I have a lean and green. When I was on it before with the doctor, I was only having five shakes a day. I survived, so I figured skipping the lean and green once a week is not going to hurt me. I feel good. The first week, I felt very tired and I had no energy, but after that, I’m fine. It was my body adjusting to the low calorie. I feel great. It’s an awesome experience.
In announcing its ranking on Forbes’ lists, Medifast described itself as “a leading portion-controlled weight-loss program.” Actually, Medifast is a very low calorie diet (VLCD) consisting of Medifast prepackaged meal replacement shakes and other foods. It’s also a multi-level-marketing (MLM) diet business, which the company calls its “Take Shape for Life” personal coaching division. Medifast also sells its program and products online and through call centers, in its Medifast Weight Control Centers and through a network of doctors. [4] [5] [6]  
There are two plans. Medifast Go was formerly known as the Medifast 5 & 1 Plan. Let me digress here for a minute; the Medifast 5 & 1 Plan was the subject of a sweeping 2012 federal investigation and lawsuit, wherein federal agencies alleged the company engaged in false advertising when it claimed you’d “lose 2-5 pounds” per week with no scientific proof of that claim. Medifast ultimately settled by paying a $3.7 million fine, but declined to admit guilt. [8] 
Q:How many carbs do you get on Medifast a day? A: With the Medifast Optimal Weight 5&1 Plan, you’ll have around 80 to 100 grams per day of carbohydrates from a daily calorie count of around 800 to 1,000. Is Medifast gluten free?
There is also the 5, 2 & 2 plan. This plan is for those seeking a diet with a bit more flexibility but one that still adheres to the Medifast program. It consists of 5 meal replacements, 2 healthy snacks as well as 2 “lean & green” meals.
A clinical study from 2015 that was published in Internal Medicine looked at 45 weight-loss programs, including Medifast. Using low-calorie diet programs like Medifast led to significantly larger weight loss compared to counseling.

As we’ve outlined above, the Medifast diet plan is a highly effective way to lose weight, and we highly recommend it for anyone looking for a healthy and convenient way to get healthy. When using this plan, they take care of everything for you; from the pre-made meals and snack they send to telling you the exact lean and green foods to buy and prepare, it’s pretty much impossible to not be successful on this diet!
