Nutrisystem Video Review


What is Nutrisystem?

Nutrisystem is a weight loss plan that takes the guesswork out of figuring what you can eat and when. It eliminates calorie counting, keeping track of carbs, and even searching for point values to stay under an allotted amount. It also gets rid of having to figure out what the proper proportions for your plate are at each meal and at snack time. Like many other diet plans, you are still restricted to a certain diet and are not supposed to eat whatever you desire.

When you embark on the Nutrisystem diet, there are several plans to choose from. You can pick the one that is right for you. You eliminate the guesswork because you purchase your meals directly from the company from a customizable menu. Each meal is nutritionally balanced, a proper portion size, and pre-calculated for calories and other factors.

Each day, you are provided with Nutrisystem prepared or easy-to-assemble breakfast, lunch, dinner, snacks, and desserts. For variety, you can also add fresh produce.

Before delving deeper into this system, let’s see what some of the research has to say about Nutrisystem:

  • Post Graduate Medicine“… data suggest that obese patients with type 2 diabetes will experience significant improvements in weight, glycemic control, and cardiovascular… risk factors after the use of a commercially available weight management program.” The weight loss program was Nutrisystem D.
  • Frontiers in NutritionNutrisystem was found to be more effective than a self-administered diet over a 16-week period.
  • Annals of Internal Medicine: Research following Nutrisystem users up to 12 months showed the program is associated with “promising weight loss results.”

Nutrisystem Facts


Nutrisystem Ingredients

Each plan comes with food chosen to supply the right combinations of nutrients and keep you healthy while you lose weight and fuel your body. Each item will have different ingredients to accomplish this. Some highlights of what the meals focus on are:

Healthy, lean protein

According to Genetics Home Reference, protein is a vital element in every cell you have in your body. Your hair and nails are made of proteins and proteins play an essential role in building bones, muscles, and cartilage. Your body uses protein to repair tissues, make digestive enzymes and hormones among other chemicals. Protein is a macro-nutrient, and your body needs a bunch of it to function properly since it is something that you use up and not store.

In weight loss, protein is important for giving your body the ability to put on lean muscle using the amino acids found in it. More lean muscle means more calories burned, even when you are not trying. You also burn more calories digesting them because it takes more for your body to metabolize and use them. Because it takes longer for them to work through your system, you will feel fuller for longer, meaning a less voracious appetite.


According to Nutrition Reviews, including high fiber in a diet to lose weight will keep you fuller longer. Adding more fiber to your eating habits is heart-healthy and helps you maintain a healthy body weight. Fiber is a carbohydrate in foods such as fruits, vegetables, and whole grains. Unlike traditional carbohydrates, fiber is difficult for your body to digest. It also satiates your appetite making you feel fuller longer without adding lots of calories to your intake.

Low-glycemic carbs

Most of us have heard the terms, “good carbs” and “bad carbs” but still likely have a hard time telling them apart.

Nutrisystem eliminates the need for you to determine which is good or bad. They use low glycemic carbs like whole grains and specific veggies (the good kind) in their meals. The more complex the carb, the longer it takes to break down in your system, as they are digested slowly. Low glycemic carbs are more complex and thus release into your blood slowly and steadily, which is better for losing weight since it keeps you full longer.


Nutrisystem NuMi

A few years ago, in 2014, Nutrisystem started new programs, one of which was NuMi®, an app that is oriented towards techie dieters with wearable health and fitness devices and platforms. NuMi:

  • Tracks Nutrisystem meals and food outside of the program.
  • Sends out meal, water, and exercise reminders.
  • Provides articles, tips and recipes on a daily basis.
  • Offers exclusive special offers, contests, and prizes.

What Does Nutrisystem Do?

Nutrisystem provides multiple diet plans that cater to specific needs and can be customized to your particular taste. It offers healthy well-balanced meals that include high fiber, low calorie, and lean proteins to help relieve cravings and keep you fuller longer to control your appetite and eating habits.

Nutrisystem Menu

With over 160 menu items to choose from, the program is sure to please anyone. The ultimate goal of individuals on the Nutrisystem plan is to lose weight and maintain a healthy weight. You’ll eat six times a day. Many options are low sodium and they remove unnecessary artificial flavors and colors, as well as potentially harmful preservatives. It’s an easy plan to follow with no guesswork as to what you can or cannot eat.

The Nutrisystem program can also be aligned with DASH (Dietary Approaches to Stop Hypertension) diet recommendations. According to Obesity Reviews, “DASH Diet is a good choice for weight management, particularly for weight reduction in overweight and obese participants.”

Is It Easy?

How Easy is Nutrisystem to Follow?

Convenience: Six meals per day with pre-counted portions, saving you time and effort.

Recipes: Dozens of high-protein, high-fiber, zero-trans fat recipes for breakfast, lunch, dinner, and snacks.

Eating Out: Extensive PDF guide on how to not derail your diet when out in a restaurant.

Alcohol: The Nutrisystem program recommends abstinence from, or limiting, alcohol consumption because “alcoholic beverages […] tend to be high in calories and often contain extensive fat, cholesterol and sodium.” In the later stages of weight loss, a glass of wine is perfectly fine.

Fullness: Besides the high-fiber, low-glycemic carb ingredients of the Nutrisystem program, the company offers a guide to help people feel full faster.

App: The free NuMi app makes following Nutrisystem easier than ever. You can track every meal with a few finger taps and know every detail of the foods you eat in an instant.


What You’ll Eat on Nutrisystem

  • Pantry items: oatmeal, cereal, pasta dishes, chili, mashed potatoes, tuna salad, mac and cheese, pizza, breakfast muffins, and cookies
  • Frozen foods: omelets, breakfast sandwiches, pizza melts, waffles, hamburgers, grilled chicken sandwiches, quesadillas, cinnamon rolls, and ice-cream sandwiches
Does It Work?

Does Nutrisystem Work?

When you control your calorie intake and your portions, you are on a good path to losing weight. Add the fact that your meals will likely be healthier than what you eat regularly and you implement an exercise regimen to burn even more calories, and the result should be that you attain your weight loss goals. If you can stick to the plan accordingly and only eat what is suggested through your prepared meals and allowed produce, research that has been done to support the success of the plan suggests that you will lose weight.

Nutrisystem Weight Loss

Another plus to the Nutrisystem plan is that you will be eating smaller meals more often, which is considered a healthier way to eat based on research. It has been found to promote greater weight loss and maintenance and the prevention of other health issues.

One challenge that you may face is maintaining the diet without all the help you got through the program. However, if you can transition back into eating “normal” food while keeping in mind what you have learned through healthy eating during the program, you should have no problem. The program progresses and helps teach the user how to cook healthy with Flex meals. Once you reach your body weight goal, you will likely be more apt to maintain healthy habits to keep your healthier appearance and feeling.

According to research in Annals of Internal Medicine, a study titled “Efficacy of commercial weight-loss programs: an updated systematic review” looked into Nutrisystem’s capabilities. It reported that “Nutrisystem participants achieved at least 3.8% greater weight loss at 3 months than control/education or counseling.”


Nutrisystem Benefits

One significant benefit to Nutrisystem is that it is easy to follow. Many people have a hard time sticking to other diets because there are calories to count, carbs to count, and points to track. Then there is often guesswork with the values of certain foods or portions. Nutrisystem takes that guesswork out. It is all prepared and counted for you. Portions are controlled, and all you need to do is follow the program.

Another benefit to the Nutrisystem program is that there are avenues of support for its members. There is an online community of others using the plan that can become a significant support group and means of encouragement as you adjust to the diet or experience any stumbling blocks or setbacks. There’s also the NuMi app packed with helpful information on Nutrisystem, weight loss, and more. The app is free.

Following The Plan

The Ease or Difficulty of Following Nutrisystem

The food available is chosen by your plan choice and comes prepared for you. No need for counting calories and carbs and there are no points to keep track of.

Nutrisystem offers a wide variety of meal choices and snack options to choose from. Its most extensive plan offers over 160. You can get the allowed add-on options on your own from the supermarket, giving you even more variety.

  • I think it was the nastiest thing I've ever tried
    mary anne (Verified Purchase)

    it really is non-edible. My brother and I both bought it and threw it out. I think it was the nastiest thing I’ve ever tried–I’d rather not eat a thing than eat that. No wonder people lose weight. Wonder if their spokespeople get better food than ordinary people do. Or, they wouldn’t promote it as being good.

  • I am trying to find some where on it that says put your serial# and pin # to activate your 14 day nutrisystem starter program

  • Tell me some encouraging stories please

    I am about to go on the diet, worried about all the money. Tell me some encouraging stories. The girl who hasn’t lost a pound in 10 days sounds awefully discouraging. Lynn

    • Anonymous

      Me and my buddy did the diet! He lost 70 lbs! I lost 30 lbs in about 6 wks! I was not even that big! Though I did excercise every day! I think it’s a great diet!

    • Jen

      Lynn, I’ve been on NS for 3 weeks today and have lost 10 lbs. I couldn’t be happier with the program. My husband jokes me saying I’m going to be the next spokesperson:) This weight has come off effortlessly with just daily walks through my neighborhood. You do have to do some sort of exercise. I went into this knowing I wouldn’t be eating all the tasty gourmet meals that got me into this predicament in the first place. I knew that if I was going to lose weight, I was going to have to make a few sacrifices, and I tell you, the sacrifices were minimal, the food isn’t that bad. I’ve read so much about the awful muffins so I couldn’t wait to see if they were actually that bad. Do they taste like ones bought from Duncan Donuts?? Of course not! For muffins offered on a weight lose program,,they’re pretty good. There was a few things that I just couldn’t tolerate,,so,,I just didn’t order them next time around, pretty easy solution. I’m NEVER hungry which is shocking for me since I’ve always been a grazer. I know of 2 other people who tried NS and had amazing results, I was at the end of my rope and was feeling desperate to lose the weight. My old habits are now broken and I feel awesome. As far as the money, sure it sounds like alot. I’m an PD officer and work nights and would spend on average $10-12 a night on fast food and junk, so we didn’t really feel the expense of it. So good luck to, stick with it and you will lose!

      • KS

        Hey Jen,

        I don’t know if you even read this anymore but I noticed you were a PD officer that works nights. I was wondering how you work the nutrisystem into your schedule. I work 10p-8am Thur thru Sun with Mon-Wed off. Thank you in advance if you or anyone can provide any assistance.

    • Debi

      My husband and I are both on the diet and he’s lost 7 lbs in the first week, and I’ve lost 4. I can’t exercise because of a mobility issue, but I have been on Nutrisystem once before for three months and lost over 45 lbs. The food doesn’t taste homemade, but most of it isn’
      t bad, and if you don’t like something you can change what you get the next time. Make sure you customize your meals. I think Nutrisystem is the ONLY diet that DOES work!

  • I sent it back
    coroline bloom (Verified Purchase)

    Hi, yes I tried nutrisystem. I sent it back, I WOULD NOT FEED THAT CRAP TO A STRAY DOG!!!Beef does not tast like that, Hey, wheres the cat!!

    • Anonymous

      I’ve switched to the veggie meals and it’s amazing. I’ve lost 20 lbs in 2 months.

    • gailani

      I’m with you coroline bloom!

    • Diane

      shouldn’t be feeding stray dogs anyway…guess they led you astray.

      started NS 1 month ago. Foods are good enough for me, most of them. Have lost 10 lbs, have not had a headache or need for Tums in 30 days, have not eaten out, which was a regular deal b4 since I am a small biz owner and didn’t have much time for anything but. now I have regular, healthier, and less expensive meals every day. If I don’t like an entree I just don’t chose it next order. simple. And I have been finding creative ways to augment entrees while keeping within the program. Folks complain about price. $239 month for me, shipping included. Add that to my cost for fresh HEALTHY fruits & veggies, and I come out ahead at about $10-11 a day. If I want to switch to other NS programs I can. I’m not stuck. I keep my food logs and use the tools as needed. I am proactive instead of sitting around waiting for something to happen. That’s what got me in trouble: too much idle/sedentary time, too much eating out & eating to feel good for the moment, then paying for it later. People can bad mouth NS all they want, not going to change my plan unless it harms me physically. And so far, i’m getting better and better. You don’t like it, try something else. Simple.

    • adam

      It’s making me feel sick and bloated. Wonder if there is a better option, jenny craig weight watchers ?

      • Sandi

        I had the same issue. Jenny Craig food did not have this impact on me.
