Nutrisystem is a weight loss program and food delivery service. This program offers several plans, including specialist diabetes and vegetarian menus.

Nutrisystem promotes short-term weight loss, but the long-term effects and sustainability are not proven.

This article explains how Nutrisystem works and who may benefit from it.

The Nutrisystem diet plan consists of eating several smaller meals each day.

Though their plans vary based on a person’s preferences and cost, some common features include:

  • 7-days worth of meals
  • breakfast, lunch, dinner, and three snacks throughout the day
  • frozen and fresh meals, shakes, and nutritional guides
  • NuMi Weight Loss App (Uniquely Yours and Uniquely Yours Ultimate)
  • unlimited support

According to Nutrisystem, eating smaller, balanced meals six times a day helps prevent hunger and promotes weight loss. However, some studies contradict this theory.

In an older study, researchers found that increasing meals from three to six a day did not impact a person’s body’s ability to burn fat.

Contrary to Nutrisystem’s claims, the researchers found that increased meal frequency might lead to increased hunger and a desire to eat.

A more recent study from 2017 had similar results. In this study, researchers found that decreasing meal frequency throughout the day, and having the largest meal in the morning helped prevent long-term weight gain.

Nutrisystem is available for purchase online.

Nutrisystem offers three different plan levels.

They include:

  • Basic: The most affordable option, but it does not include premade meals for every meal. This means a person will need to make some meals and provide their own snacks.
  • Uniquely Yours: This option has slightly more variety than the basic option and includes frozen meals. The plan supplies frozen and non-frozen meals for 5 days of the week.
  • Uniquely Yours Ultimate: Has the most variety and includes frozen and non-frozen meals for every day of the week.

In all plans, a person will need to use some fresh ingredients from the grocery store. In the Basic and Uniquely Yours option, a person will need to cook some meals and provide some of their own snacks.

Couples and families can also get combination plans that cover the different requirements for each person in the house. All meal plans come with the use of the Nutrisystem NuMi Weight Loss App.

A 2015 review evaluated Weight Watchers, Nutrisystem, JennyCraig, and other dietary programs. The authors recommended both Weight Watchers and JennyCraig for weight loss.

They stated that Nutrisystem showed promise but that researchers needed to conduct further studies on its long-term effects. This means that Nutrisystem may help a person lose weight in the short term, but its long-term effects are still unknown.

People looking for a convenient option to lose weight may find the Nutrisystem program helpful. It helps take the guesswork out of meal planning and reduces the amount of effort needed to make meals each day. But it is more expensive than planning and buying food at a local store.

Nutrisystem offers plans for people with health conditions and dietary preferences.


Nutrisystem offers a dietary option geared towards people living with diabetes. The diabetes option is also similar in price to their other dietary plans.

The diabetes plan includes meals and snacks that a person eats every 2–3 hours to help keep their blood sugar levels steady. The foods also aim to help a person feel fuller for longer.

According to Nutrisystem, their plans will help with:

  • managing blood glucose levels
  • weight loss

A 2009 study supports the use of dietary programs for helping people with diabetes. The researchers found that people living with obesity and type 2 diabetes saw improvements in weight, glucose control, and cardiovascular disease risk.

Nutrisystem claims to help with weight loss, which can benefit people living with obesity. Some studies support these weight-loss claims. However, the long-term effects and sustainability of the program are still unclear and require further research.

People following a vegetarian diet plan can still use Nutrisystem. The vegetarian plan is more expensive than the Basic plan, but not as expensive as their Ultimate plan.

Nutrisystem offers specialized plans for males. The menu includes more snacks and more calories for males than the plans for females.

There are other programs similar to Nutrisystem.

They include:

All dietary programs and menus are slightly different. A person should look for a program or plan that works best for their needs.

Before making dietary changes, a person should talk to their doctor or nutritionist, who can help them choose the best option based on their health and dietary needs.

Nutrisystem may help with short-term weight loss goals. However, studies demonstrating its long-term effects are lacking. A person should talk to their doctor or nutritionist before starting a new dietary program, particularly if they have an underlying health condition.

Nutrisystem may help a person lose weight, but it may not be a solution that works for long-term success.
