Medifast vs Nutrisystem – What’s the Difference and Which is Best?

Medifast vs Nutrisystem: Which is the Best?

Every year millions of people around the world pledge to lose weight and get healthy in the New Year. Unfortunately many fail within the first few weeks, but some go on to succeed and become the healthiest versions of themselves in a long time.

There are hundreds of different diet plans that people will try in an effort to lose weight (check the top diets). Some don’t work while others do. So which ones are the best?

While many people succeed with working with a personal trainer and eliminating the unhealthy food in favor of colorful vegetables and lean protein, some people need a little more help in the means of pre-packaged portion-controlled meals.

The Medifast Diet and Nutrisystem Diet programs have each been around for several decades. Millions of people in the United States have had great success with each program over the years.

While each program is quite similar, Medifast and Nutrisystem do have their differences. Of course, portion control is one of the benefits of both programs (portion sizes have long been a key to weight loss program success).

Bottom Line Up Front: We prefer the modernized green meals with more choices and more fresh ingredients offered by Nutrisystem here. Another advantage is that Nutrisystem offers better introductory offers here, compared to Medifast.

Let’s begin the investigation of what these diet plans have to offer, what makes them good food choices, and some things to consider when choosing a new diet plan!

About the Medifast Diet

Dr. William Vitale developed the Medifast Diet in 1980 based on a long clinical heritage of facilitating weight loss in thousands of patients over the years as a registered dietician.

Today, over 20,000 doctors have recommended the Medifast diet program across the country to their overweight and obese patients. While the original diet was only available under the guidance of a doctor’s supervision, Medifast is now available on the mass market for at home use.

Many diets and weight loss programs require people to track calories and keep food journals, but Medifast is different. Medifast is a meal delivery service that sends high protein meals directly to your home. No more trips to the crowded grocery store on Sundays when you’d rather be at home playing with your kids.

Medifast Menu In General

The Medifast diet consists of a menu of shakes, bars, soups, and other side dishes that you can pair up to create your desired menu of the day.

This is an easy way for portion control, and with over 70 meal options are available to satisfy everyone’s unique palate and dietary needs. Kosher, low glycemic, lactose-free and vegetarian options are all available on the Medifast Diet plan.

Each day you will eat five prepared meals with one being a “Lean and Green Meal,” often referred to as the Medifast 5 & 1 Plan. The “Lean and Green Meal” consists of a lean protein (like chicken, turkey or fish) with a tablespoon’s worth of condiment (i.e., ranch dressing, ketchup, etc.) and a side dish of your choice.

Side dish options generally consist of a salad, raw or cooked vegetables.

The Medifast Diet recommends that you eat every three hours to encourage your body to keep your metabolism high and avoid hunger. When you start to feel hungry this is when people start to slip up and eat unhealthy snacks. Dieters tend to enjoy this part of the diet because there is less time to feel hungry. Here are some of the best Medifast foods to eat when you feel hungry, and to obtain weight loss results while doing it.

At the beginning of your Medifast Diet plan, you will remove all high carbohydrate vegetables, like corn and carrots, to help jump-start your weight loss goals.

Over the past 20 years, people have had great success with the Medifast Diet. Several clinical research studies, including one from John Hopkins, found the Medifast Diet to be safe and help people quickly and safely lose weight by decreasing the number of calories they consume on a daily basis.

The Verdict – Which to Choose?

Bottom Line: We prefer the modernized green meals with more choices and more fresh ingredients offered by Nutrisystem here. Another advantage is that Nutrisystem offers better introductory offers here, compared to Medifast.

Both the Medifast and Nutrisystem Diets are very similar. Both are leading portion-controlled, low-calorie meal delivery services. Each plan offers pre-packaged pantry-ready and frozen meals and snacks to help losing weight. Both plans provide you with three meals and two snacks a day.

Both plans are expensive and average between $300 and $400 a month; however, Nutrisystem often offers special discounts on their plans to help you save money. If you have any dietary needs, such as gluten-free or lactose-free then Medifast is your best choice.

While the Medifast delivers everything you need for your meals to your doorstep, the Nutrisystem diet requires you to still go to the grocery store to purchase fresh vegetables, fruits, and fish.

At the end of the day, both plans are very similar and it is best to look at the food options for each plan to determine which program seems tastier to you. Both plans offer trial packs to help you determine if the plan is right for you.
