What is Nutrisystem Lean 13?

For starters, Nutrisystem Lean 13, also referred to as Turbo 13, is a weight loss program that helps you drop up to 13 pounds and 7 inches in your first month. If you’re a guy, you can drop up to 15 pounds and 7 inches in your first month.

This is one of several diet plans offered by Nutrisystem, and it involves portion control, balanced nutrition, and frequent meals. This system is supposed to accelerate your weight-loss results. Here is what you can expect to eat on Lean 13:

  • Prepackaged meals
  • Nutrisystem Shakes
  • Bars
  • Snacks

There is no counting calories, carbohydrates or points. After all, the Nutrisystem food is already portioned out. However, it does provide high levels of protein and fiber, but with zero trans fat.

Also, if you’re wondering about exercise, You do not have to exercise with Nutrisystem programs, but it is encouraged.

Put plainly; they say you will lose weight just by eating what they tell you to. But, if you add regular exercise, you will lose even more weight.

They suggest single 10-minute sessions, three times daily, such as walking, gardening, running, and simply moving more.

As reported by the Mayo Clinic and Harvard Health, studies have demonstrated that adding physical activity to your daily routine will help you lose pounds, stay fit and manage your weight.

Turbo Takeoff Kit

Nutrisystem Turbo Takeoff Kit

The Turbo Takeoff Kit is mostly a box that includes a 1-week supply of Nutrisystem Turbo Shakes, NutriCurb Bars, snacks and daily meals. This combination of foods is supposed to help jumpstart your weight loss efforts. It enables you to get used to the prepackaged foods and cuts your calories to help you start shedding pounds.

You are also told to eat at least four servings of non-starchy vegetables each day. After the first week is over, you can then pick and choose the Nutrisystem foods you want.

To get a better idea of how Nutrisystem Turbo 13 works, here is a quick rundown of how you will eat each day:

Nutrisystem For Men

There is a specific section on the Nutrisystem website that addresses the men’s plans and weight loss options. It states that men can lose weight, burn off fat and retain lean muscle mass on these programs.

As with Nutrisystem for women, all of the food is already prepared and prepackaged so there’s no counting calories or trying to figure out how much you can eat.

However, the men’s plans are slightly more expensive since they do include a little more food. It also mentions on the website that results vary depending on your starting weight and the “program adherence.” In other words, it’s imperative to stick to the specific eating program if you want to see that 15 pounds of weight and 7 inches gone in the first month.

Nutrisystem Lean 13 for Men

Nutrisystem Food Calories and Portion Control

One of the main aspects of the Nutrisystem Lean 13 diet program is the meal delivery and prepackaged foods. You have over 150 food different choices, and the primary key to this system is eating six smaller portions throughout the day. This means no large or heavy meals, which can lead to more weight gain. From what we gathered, you can also incorporate some fresh fruits, vegetables, and snacks if desired.

Since all of the Turbo Shakes, snack bars and foods are premade and have a specific number of carbohydrates, fats, sugars, protein, vitamins/minerals, and fiber; you don’t have to figure anything out on your own. You just stick to the Nutrisystem plan, and you will not go over your daily allowance or food portions and calories.

With the Nutrisystem diet program, you eat 1,200-1,500 calories per day.

Research has shown that reducing your daily caloric intake can lead to weight loss. For instance, the average calorie diet plan is 2,000 per day for an adult, so if you reduce this calorie intake by 500, you are sure to lose weight over time. This is because your body has fewer calories to work with. Studies published in the Annals of Behavioral Medicine and Obesity Research confirm this.

Eventually, you will burn off excess body fat.

However, some people have complained of feeling hungry while on the Nutrisystem diet. Not to mention, others have complained about the food options and the overall flavor of the prepackaged meals, shakes, and bars.

Side Effects

Any Nutrisystem Lean 13 Side Effects?

Since Nutrisystem Lean 13 is a weight loss program that involves eating lots of prepackaged meals, snacks, shakes and processed foods, some people do experience specific side effects while on this diet. Some of the more commonly reported reactions are:

  • Bloating
  • Gas
  • Abdominal discomfort
  • Upset stomach
  • Diarrhea
  • Constipation

This is due to the processed ingredients and dietary fiber in Nutrisystem foods. These snacks, shakes, and bars are also loaded with preservatives, sugar alcohols and synthetic nutrients. Research has shown that it is always better to eat whole foods, as opposed to manufactured foods and meal-replacement supplements, the Mayo Clinic reports.

This is because of the higher nutritional value in whole foods. For instance, natural foods contain more nutrition, essential fiber, and protective antioxidants.

Just to be clear, not all dieters will experience unwanted side effects with Nutrisystem Lean 13 meals and snacks. It just depends on how your body responds to these bars and shakes. While some customers mention no adverse effects, others say they have gas and bloating all the time while on the Nutrisystem diet.

Nutrisystem Lean 13 Research

In a word, yes. There is some science and research that supports the Nutrisystem approach to weight loss. Studies have shown that portion control and calorie restriction helps you lose weight over time, as long as you stick to the diet plan and don’t add other foods along the way.

Also, this company boasts 40 years of experience with safe and effective weight loss, which excludes any fads or gimmicks. So, it has been around a while.

The Mayo Clinic breaks down calorie reduction like this, “Because 3,500 calories equal about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you’d lose about 1 pound a week (500 calories x 7 days = 3,500 calories). It isn’t quite this simple, however, and you usually lose a combination of fat, lean tissue, and water. Also, because of changes that occur in the body as a result of weight loss, you may need to decrease calories further to continue weight loss.”

This is helpful because it gives you a solid idea of what people think of this diet system and how they rate it in comparison to others. The feedback we found is very mixed, both positive and negative. While some people said they lost weight with this program, others said it did nothing for them.

There are some success stories posted on the official website. These are before and after photos with names and the amount of weight each person lost. However, these success stories may not apply individually to Nutrisystem Lean 13. There are also celebrity testimonials, one of which is Marie Osmond, the spokesperson for this company, who lost 50 pounds.

On a separate note, we did find numerous complaints about the taste of Nutrisystem meals and foods. This is certainly a big factor to consider because if you can’t handle the taste of these snacks, shakes, and entrees, this diet system will not work for you. After all, you need to eat these prepackaged foods the entire time you follow the Nutrisystem diet.

Does Nutrisystem Lean 13 Work

Does Nutrisystem Lean 13 Really Work?

Well, as with any diet or weight loss program, you need to consider whether or not it’s a viable choice for you. As for Nutrisystem Lean 13, this system involves eating a lot of prepackaged meals, shakes, and bars. This is not for everyone. Just take a look at some of the Nutrisystem reviews posted around the web. Many people get very tired of the food options quickly.

On the other hand, this plan does involve reducing your daily calorie intake, which can help you lose weight. After all, cutting out calories is a proven way to drop some unwanted pounds. Unfortunately, some customers say that Nutrisystem leaves them feeling hungry and unsatisfied, which is likely to make them stop the diet plan altogether.

So, Nutrisystem Lean 13 can potentially work if you’re okay with eating all of the processed foods and prepackaged meals every day. However, this is probably not the most significant choice for the long term. As stated by WebMD and Food & Nutrition Magazine, dietitians and nutritionists recommend eating mostly whole foods for optimal health and weight management.

What Users Are Saying

“The Nutrisystem seemed a program I could follow, so I joined. In 3 weeks, I have lost over 20#, although hungry, my physical condition is improving.”

“Cancelling is a hassle. I’ve called multiple times, the “system” says my program is cancelled but I haven’t received a refund yet.”

“Let me say that the Nutrisystem plan is working and I am happy about that.”

Bottom Line

The Bottom Line on Nutrisystem Lean 13

With Lean 13, Nutritsystem takes a fresh look at using meal replacements for weight loss. The plan isn’t far from the original Lean 10, but when you’ve been in the same business for so many years, drastic changes are not a business savvy decision. At the end of the day, science says programs like this work as long as the dieter sticks with it and takes the time to learn how to cook healthier. This makes the transition from prepared foods to cooking at home much easier.

If you ready to finally start losing weight for good, programs like Nutrisystem Lean 13 aren’t a bad idea. We also suggest a clinically tested supplement that aims to help reduce hunger and spark metabolism. A healthy diet and strong supplement could be the one-two punch you need.

Among the best products we’ve seen is Burn TS. We like that each of the four ingredients have clinical testing showing a direct, or indirect, benefit to people losing weight. It’s also satisfying to see all the positive user reviews.
