Medifast is based in Maryland and while shakes are one of their most prominent products, they are just one of several “Medifast meals,” along with low-calorie bars and brownies, that you can incorporate into their weight loss plan. Every Medifast meal is about 100 calories and most of the company’s weight loss plans involve four or five Medifast meals per day, so let’s see if the French Vanilla flavor meal replacement shake holds up to scrutiny.

Medifast Meal Replacement Shake Nutrition and Ingredients

One serving comes in a packet and delivers 110 calories: 14 grams of protein, 13 grams of carbs (4 grams of fiber, 7 grams of sugar). There’s just 2 percent of the recommended daily intake of cholesterol and 11 percent of your daily sodium.

As far as other micronutrients go, one serving has 20 percent of the RDI of a slew of vitamins and minerals, including the obvious ones like B-vitamins, Vitamin C, iron, and calcium, to the not-so-obvious ones like Vitamin D, magnesium, zinc, chromium, and copper.

The protein is a combination of soy and whey and the rest of the ingredients are mostly natural and artificial flavors, thickeners and stabilizers, and the artificial sweetener acesulfame potassium.

Medifast Meal Replacement Shake Benefits and Effectiveness

So those are the upsides: 20 percent of most of your daily nutrition. Some people scoff at “20 percent,” thinking that a nutritious shake should provide as close to 100 percent as possible, but remember that Medifast does often recommend taking 4 or 5 of these shakes per day along with one or two nutritious, balanced meals.

Indeed, it is important to have at least one nutritious meal with a considerable amount of fat, there’s just half a gram of fat per serving. Even five of these shakes won’t bring you to 5 grams, and a daily intake is usually recommended as somewhere between 45 and 75 grams.

Micronutrient-wise, this is a pretty impressive product, particularly since it has a decent amount of Vitamin K and potassium, two nutrients that are often left off of meal replacements.

One potential downside is that there aren’t any ingredients geared toward digestive health, like digestive enzymes, prebiotic fiber, or probiotic bacteria. It also contains artificial sweeteners and flavors, which some people try to steer clear of.

Medifast Meal Replacement Shake Price

You can buy these packets on their own, in a box of 7 packets for $20, or a case of 84 packets for $234. In any case, the price is roughly $3 per serving. That’s pretty expensive, but Medifast also offers a lot of kits that include other products that can lower the price somewhat, but you’re unlikely to find a Medifast meal for under $2.50.

Medifast Meal Replacement Shake Taste

The French Vanilla shake tasted like a marshmallow rice crispy square, and I loved it. It’s not naturally flavored, but the artificial flavors come together to make for a pretty darn tasty drink. I mixed it with water; make sure it’s extra cold.

The Takeaway

I was pretty impressed by the taste and the breadth of micronutrients in Medifast’s meal. The main drawbacks are the lack of ingredients for digestive health and the extremely low fat content. If you’re planning to consume 4 or 5 of these per day, make sure your whole food-based meals aren’t low fat. Besides that, Medifast has a lot going for it.

Nick is a content producer and journalist with over seven years’ experience reporting on four continents. His first articles about health were on a cholera outbreak in rural Kenya while he was reporting for a French humanitarian organization. His next writing job was covering the nightlife scene in Shanghai. He’s written on a lot of different kinds of things, but his passion for health ultimately led him to cover it full time.Shanghai was where he managed to publish his first health related article (it was on managing diarrhea), he then went on to produce a radio documentary about bodybuilding in Australia before he finished his Master’s degrees in Journalism and International Relations and headed to New York City. Here, he’s been writing on health full time for more than five years for outlets like Men's Health, VICE, and Popular Science.Nick’s interest in health kind of comes from an existential angle: how are we meant to live? How do we reach our potential? Does the body influence the mind? (Believe it or not, his politics Master’s focused on religion.)Questions like these took him through a lot of different areas of health and fitness like gymnastics, vegetarianism, kettlebell training, fasting, CrossFit, Paleo, and so on, until he realized (or decided) that strength training fit best with the ideas of continuous, measurable self improvement.At BarBend his writing focuses a little more on nutrition and long-form content with a heaping dose of strength training. His underlying belief is in the middle path: you don’t have to count every calorie and complete every workout in order to benefit from a healthy lifestyle and a stronger body.
