Nutrisystem: Here’s How The Diet Works (Does It, Really?) • 2018

nutrisystem logoDoes Nutrisystem really work? You’ve seen the commercials, heard the celebrity endorsements, but may be wondering, “How Nutrisystem works, and DOES it actually work? To answer that question, let’s answer the following:

*2018 Update: Lean 13 has been replaced by “Turbo 13” for faster weight loss in your first month.

First, How Nutrisystem Works

woman learnedNutrisystem is a monthly meal-delivery diet based on a combination of balanced nutrition, portion control, and calorie restriction.

The main idea is that you burn more calories than you consume, and losing weight is easier when your eating habits are structured. With Nutrisystem you Start quickly with Turbo 13 and eat 6 smaller meals and snacks a day, which helps to control your blood sugar and improve your metabolism.

These meals are high in protein, “smart” carbs, and fiber which makes you feel fuller, longer. You supplement these prepared meals with fresh fruits and vegetables from the grocery store.

Nutrisystem knows that most diets fail because of bad eating habits. Also, determining food nutrition, portion size, and preparation are time consuming and frustrating. Nutrisystem takes most of the burden off the consumer by providing meals that are pre-made, measured, and “perfectly portioned” so that you know exactly what to eat and when without thinking about it first.

There Are 4 Plan Level Options:

Nutrisystem now offers 4 plan levels: Basic, Core (most popular), Uniquely Yours, and Uniquely Yours Plus for both women and men. (More info) Each plan also offers a version especially for diabetics and vegetarians. The main difference between plans is that you’ll pay more (costs) for a broader selection of prepared and frozen meal options, and their new “Uniquely Yours Plus” plan also comes with 28 protein shakes each month.

All plans start with Turbo 13, which jump-starts your weight loss with healthy meals, shakes, and bars that help regulate your blood sugar and boost your metabolism. Turbo 13 also includes an app for easy tracking and customer support.

Nutrisystem claims that during the first month:

  • Women will lose as much as 13 pounds and 7 inches
  • Men will lose up to 18 pounds and 8 inches

*Update: Nutrisystem now offers an optional “DNA Body Blueprint” test kit with all plans or a la carte. learn more

Really, it’s simple math: while on Nutrisystem you will burn more calories than you consume, resulting in a steady weight loss of 1-2 pounds per week.

Users Were Asked, “Does Nutrisystem Really Work?” Let’s Consider 292 Ratings:

Because the Nutrisystem success rate isn’t published, one good way to determine whether it works is to compare the number of positive reviews versus negative reviews.

Let’s look at the 292 customer ratings for “overall satisfaction” at consumer

Nutrisystem: Customer satisfaction

Nutrisystem success rate: Overall satisfaction ratings

  • 5-Star Ratings, (Positive): 195
  • 4-Star Ratings, (Positive): 38
  • 3-Star Ratings: (Neutral): 11
  • 2-Star Ratings: (Negative): 11
  • 1-Star Ratings: (Negative): 37

These ratings are not sorted by group such as seniors or diabetics, so we can’t deduce whether the diet works better for certain demographics than others. So, based on that sampling of nearly 300 people willing to review and rate Nutrisystem, an impressive 79% rated Nutrisystem positively.

7 Reasons Why Nutrisystem Might NOT Work For YOU:

nutrisystem not work

Nutrisystem doesn’t work well for everyone, but that’s why there’s vanilla and chocolate, right? Customers tend to overall be very pleased with their results on Nutrisystem, but complaints do occur.

Scouring through the plethora of reviews, it’s worth noting reasons why Nutrisystem didn’t work for disgruntled customers. Here are some top reasons why Nutrisystem ultimately did not work for some people. You might not like:

  1. Relying mostly on prepared meals
  2. Taste of the food
  3. Too demanding (eating every 2-3 hours) 
  4. Too expensive
  5. Limited food selection (prefer to cook)
  6. Doesn’t work long-term
  7. Anger about the early cancellation fee

It seems that Nutrisystem’s strength is it’s convenience, as it works well for busy people who don’t look forward to cooking or guessing about portions. However, its weakness is that you must rely heavily on pre-packaged foods delivered each month.

Convenience and limitation seem to be two sides of the same coin with diets. If you don’t like the idea of prepared food, (or paying for a month of food at once) you can consider Weight Watchers, which relies on a point system instead of meal delivery.

Is Nutrisystem Effective?  What the Studies Say:

medical study results success rate

Excuse me, Sir. Are you really a doctor?

Online ratings and reviews are helpful to predict whether Nutrisystem will work for you, and you can also check out the (sometimes boring) research out there that has been done to answer that question.

The frustrating thing is that medical associations always stop short of saying that a diet actually “works”, but they can provide some helpful statistics and success rates. Here are a few:

  • The New England Journal of Medicine concluded that diets, including Nutrisystem, that offer calorie restriction and portion control, tend to encourage weight loss; more so, in fact than diets that are demand individual meal planning and moderation. In other words, having Nutrisystem tell you what to eat and when seems to increase the likelihood that the diet will work. – source
  • The Annals of Internal Medicine found in a 2015 study that people on Nutrisystem lost about 4% more weight after 3 months than those who received only weight loss counseling – source
  • A 2009 Nutrisystem-funded study of obese people with Type 2 diabetes found that the 70 participants lost an average of 18 pounds over 3 months on the Nutrisystem D plan. This same group lost an average of 24 pounds after the 6th month. The control group, given nothing but weight loss counseling, lost only 1 pound after 3 months, and 5 pounds after 6 months (which infers that Nutrisystem does indeed work) 
  • Nutrisystem Rated #5: In a rating of all diets by U.S. News, Nutrisystem is ranked #5 overall for “Best Commercial Diets,” and scores highest in the “Easiest to Follow” (#11) and “Best Fast Weight-Loss Diets (#14) categories.

Anyway, the medical studies are a slog to read through, but I think the takeaway here is that if you follow the diet, Nutrisystem should work do to the calorie restriction and portion control that the plan offers.

Does Nutrisystem Work Without Exercise?

Exercise improves your metabolism while providing a wealth of physical and mental health benefits. Consequently, users who incorporate exercise into their weekly routine can expect better weight loss results and overall health.

In fact,  Nutrisystem emphasizes that “regular physical exercise is an important part of lifelong weight management, and overall health and wellness.” As a result, they encourage users to meet or exceed the national health recommendations of 150+ minutes of moderate physical exercise or activity per week while on the program.

To help users with exercise goals, Nutrisystem offers the My Daily 3® plan plus weight loss activities and exercises on the MuMi app. The objective is to help you achieve 30 minutes of enjoyable exercise or physical activity each day; either all at once or in smaller segments throughout the day.

Nutritional info: Is Nutrisystem Healthy?

is nutrisystem healthy

Their food is high in protein, “smart” carbs, and fiber. The meals have no artificial sweeteners, colors, flavors, or trans fats. Ok, that’s a good start. Let’s look at the nutritional info.

1. Nutritional Info: (Daily) 

Here’s how Nutrisystem stacks up against the recommended daily allowances of calories and nutrition: (for women on a diet)

 Nutrisystem: (Women)Daily Recommended:
Calories:1200-15001200-1600 (source)
Carbs:170g135-195g (source)
Protein:77g46g (source)
Fiber:36g25g (source)
Sodium:1900-2300 mg2300 mg (source)
Fat:28g40g (source)
Sat. Fat:6-9g9-12g (source)

*Based on recommended daily amounts for women on a diet. You can view health and nutritional information for men here

2. How Many Calories?

Consider that a pound of fat contains about 3500 calories. That means if you are going to start dropping pounds, you have to reduce the number of calories you eat each day so that your body switches to burning calories from fat instead of carbs.

A healthy intake of calories is about 2000 per day, so to lose weight you have to aim for a lower number than that.

A day of Nutrisystem food amounts to 1200-1500 calories per day to achieve a sustainable 1-2 pounds of weight loss per week.

3. How Much Sodium?

A lot of people ask if Nutrisystem is high in sodium because it is based on prepared food. A day of their meals has 1900-2300 mg of sodium, which is just within the FDA’s recommended amount, but well below the average American’s daily intake of 3400 mg.

So, compared to the amount of sodium you might already be getting, Nutrisystem would be a healthy improvement.

However, if you have diabetes, high blood sugar, or are older 51, your doctor may prefer that you stick to a low-sodium diet of 1500 mg of sodium per day such as Nutrisystem D.

4. How Many Carbs?

Is Nutrisystem a low-carb diet? No, Nutrisystem is not officially a “low-carb” diet, although their food is generally low in carbohydrates, especially during the initial Turbo 13 phase. A true low-carb diet requires that you eat fewer than 100 carbs a day, which is very low and a bit controversial among nutritionists who champion the value of “good” carbs.

The Nutrisystem diet provides about 170g of carbs per day which is within the recommended amount to achieve weight loss. This is more carbs than diets (Atkins, Paleo, South Beach) which brand themselves as being “low-carb.”

Remember that not all carbs are equal, as some carbs are very healthy, such as those from vegetables, brown rice, and whole grains. Nutrisystem targets these “good” carbs, which are the best source of energy for your mind and body.

5. How Much Protein?

Protein is the building block of muscle, bone, skin, cartilage, and even blood. Lean protein has numerous benefits. to your health, and is the foundation of the Nutrisystem meals and bars.

Protein is also the foundation of the Nutrisystem diet. Their plans for women and men (drop 18 now!) provide about 75-80g protein per day which is significantly more protein each day than the FDA’s recommended amount at over 70g per day.

6. How Much Fiber?

The health benefits of fiber include controlling blood sugar levels, healthy bowels, (hey, that’s a great name for a band!) and achieving healthy weight. Nutrisystem food has about 36g fiber per day, which is 40% more fiber than the recommended daily amount. They also ask you to supplement their prepared meals with high-fiber fruits and non-starchy vegetables from the grocery store.

Conclusion: I Would Say that Nutrisystem Is a Healthy Diet

Nutrisystem is high in protein and fiber and low in bad carbs. The diet is also within the recommended daily amounts of caloriessodium, and fat. Because of this data, I would say yes, Nutrisystem is healthy.

Success Rate: So, Does It Actually Work?

woman learnedBased on reviews, Nutrisystem works for about 4 out of 5 customers, but that doesn’t mean it will work for you. Diets are a bit like presidential candidates, in the sense that they all advertise themselves as being “the best” even though they have weaknesses and can’t possibly please everyone.

Really, you have to find a diet that fits your needs and lifestyle. Think of a diet as a “tool;” if your life is imbalanced, you don’t exercise regularly, or you lack discipline in following through with what is required, you are going to have trouble finding success with any diet.

If you are a busy person who values convenience over freedom of choice and variety of foods, then Nutrisystem is more likely to work for you.

If you don’t like the idea of meal delivery (and certain foods being off-limits) or you benefit from the extra support of in-person meetings, then Nutrisystem probably won’t work as a long-term weight loss solution for you.

  1. Gluten Free Bob

    I found this link on reddit. I’m a senior. Does this diet work for seniors, or does it just make you poop a lot? Plus, I need gluten-free products that taste good.

    1. Pamela Brucks

      I didn’t experience increased pooping, however, older people using this diet are at an increased risk for gallbladder inflammation. It is unknown why, but if you have digestive issues to begin with, you may want to try another diet. I am starting Nutrisystem again next week, it always works for me and usually I’ll gain back 5 pounds in Christmas season so this is a yearly tune up for me. I am in my mid 50s. RN in Seattle

  2. Betsy

    I’ve gone on Nutrisystem twice and it worked both times for me. I can’t afford to stay on it for years, but I lost 20 pounds on it 3 years ago, and am on it again and I’ve lost 12 pounds in the first month. If you don’t mind a lot of prepared food it should work for you for at least 6 months.

  3. Kevin

    I am in the senior age bracket and I was on Nutrisystem 2 years ago. I started in April and lost the advertised 10 pounds in the first week. Every week after that I continued to lose weight at lesser levels and after 30 pounds in 3 months the weight no longer came off. The diet does have a high fiber count but no higher than the recommended FDA listings. yes, you do go to the bathroom regularly but most seniors do not eat enough fiber anyways. After the first month and having tried everything they sent I started to order a-la-carte. Choosing your own meals makes the dining easier but the better tasting food is also more expensive.

    I work a distance from home, my wife is away on travel for most the weeks so I do most of the weekly house maintenance and as such dont have a lot of time to exercise. I feel that is mostly why I stopped losing weight.

    I decided after 6 months, 3 of which showed no weight loss beyond the 30 that I would stop and save myself the $450 a month and portion control myself. Even though I watched how much I ate, the weight started to come back. Now a year and half later I am right back at my starting weight.

    Nutrisystem does work. It is expensive and they dont really give you the information you need to be able to go it alone without their prepared meals. Also, alcohol is off the menu unless you want to go without one of the daily snacks. If you do go without then you are allowed one regular glass of wine.
    I am contemplating going back on Nutrisystem but I dislike the yoyo effect.
