The Medifast Diet

The Medifast diet is a very low calorie diet designed to cause fast weight loss. The Medifast diet is a meal replacement diet, and Medifast meal replacement products are available only through the Medifast company. Medifast was once available only with a doctor’s prescription, and the Medifast company continues to recommend that Medifast dieters remain under medical supervision until they’ve reached their weight loss goals and go off the diet.

The Premise

The Medifast diet is a meal replacement diet. You’ll need five meal replacement products a day. The Medifast company manufactures and sells shakes, meal replacement bars, soups, breakfast cereals and puddings. You’ll eat one meal a day, consisting of a serving of lean meat and two cups of vegetables.
The Medifast diet is a meal replacement diet. You’ll need five meal replacement products a day. The Medifast company manufactures and sells shakes, meal replacement bars, soups, breakfast cereals and puddings, and they claim you can lose weight rapidly, up to 20 pounds in 30 days. You’ll eat one meal a day, consisting of a serving of lean meat and two cups of vegetables.

The Diet

On the Medifast diet, you’ll eat every two to three hours, either a meal replacement product or your one daily meal. You’ll also need to drink at least 64 ounces of water each day to help your body flush toxins. You’ll consume between 800 and 1000 calories per day on the Medifast diet.

The Medifast company produces a wide range of meal replacement products, over 70 in all. They cater to the needs of many, including teens, vegetarians, new mothers, senior citizens, gout sufferers and those who have recently undergone bariatric weight loss surgery. The Medifast diet promises a loss of two to five pounds a week, without compromising your muscle mass.

Most Medifast dieters spend about $300 a month on meal replacement products manufactured by Medifast. On the Medifast diet, you’ll eat one traditional meal per day. This meal should consist of a serving of lean meat or fish. Grill or bake your meat or fish rather than frying it.

Eat two cups, or about three servings, of vegetables with your daily meal. You can boil, bake, steam or grill your vegetables, or you can eat them raw. The Medifast diet is a low carb diet, so some vegetables, like potatoes and peas, are excluded because they’re high in carbs. Dairy, grains, sweets, fats, fruits, alcohol are excluded, as are high calorie, sweetened beverages.

What to Get Excited Over

The Medifast Diet is easy and effective. It’s nutritionally formulated to meet all of your vitamin and mineral requirements, and it’s high in protein to suppress feelings of hunger. The Medifast diet is appropriate for almost all dieters.

Things to Consider

It’s dangerous to lower your calorie intake as much as the Medifast diet requires. Rapid weight loss can slow your metabolism and make it harder to keep weight off long term. You’ll need a doctor’s supervision while you’re on the Medifast Diet. The Medifast Diet doesn’t help you establish healthy exercise and eating habits.

The Verdict

The Medifast Diet seems more like a quick fix than a permanent solution. If you proceed with this diet, exercise caution and obtain medical supervision.

    I did MF three years ago and lost 50 pounds in five months. It’s the only diet that’s ever really worked for me. I must admit, I did have energy on this diet and felt pretty good after the first week. I didn’t exercise very much (a little every day, but I didn’t kill myself) and I lost very little muscle. It was almost pure water and fat loss. I was in pretty good shape by the time I finished.

    The good part about this diet is that it just so easy. No weighing or measuring. You don’t have to think about it. Psychologically, it was a huge relief NOT to have to think about food at all. It’s been such a frustrating issue for me for so long to not have to stress about my next meal or shopping or cleaning was a nice break.

    But it did suck. It took every ounce of willpower and distraction that I could muster to stick with it. And there were some unwanted side effects.

    The problem with using MF long term is that it’s so low in fat. This caused me to have very dry skin and some thinning of my hair. I also developed gallstones. Gallbladder attacks are not fun. My doctor told me that this was from not eating enough fat for the gallbladder to contract and clear itself daily. She told me to get at least 15-20g in one serving every day to avoid this in the future. The other issue is that I ended up with a shortage of fat soluble vitamins. MF does have them in their food, but you can’t use them without fat. The final problem was the lack of salt. This led to a cardiac event (mild) and an IV in the ER.

    After some research, I’m just now trying MF again. This time, I’ll get my fat in the form of fish oil, coconut, and MCT oil. I’ll have some broth and pickles for the salt. Enjoy my salad with meat and a bit of cheese and full-fat dressing.

    MF is fantastic for short-term use. Maybe 6-8 weeks to get into that wedding dress or to give you that final push to take off the last ten pounds. But, by itself, it’s too extreme to stick with for months and months without a bit of tweaking.

    Coming off the diet, you MUST have a plan. They have a transition program that I tried to stick with, but (I’ll admit it) I lost my mind. I have never been so hungry as I was when I was transitioning back to real food. Fortunately, I stuck with meat, eggs, cheese and tons of veggies – very little bread and NO sweets – and I managed to only regain six or seven pounds. But that month I pigged out on roasts, chicken, sausage, and any other fatty protein that I could shove into my mouth. I was starving for it. Eventually my appetite did settle down and I maintained there for a few months quite comfortably.

    Then I quit smoking. That resulted in another 15 pound gain, but that was to be expected.

    Shortly after that I had major surgery. Two years of bed rest and pain meds led to a 45 pound gain.

    Finally, I’m recovered enough to get my body back and I know, from experience, that MF is the only thing that I can depend on to make that happen.

    I did want to add: The reason I explained about regaining the weight is to show that it wasn’t a failure of MF. I had some pretty extreme circumstances. Before everything fell apart – and after the month-long fat feast – I was maintaining quite easily. I did have a MF shake for breakfast (I’m not a big breakfast eater, so that was better than nothing) and sometimes I’d have another for lunch if I were busy.

    MF does work, but one should be aware of the potential problems and have a plan for coming off.
