Nutrisystem is a popular weight loss program that's been around since the 1970s. The premise of the diet is simple: Eat six small meals per day to help prevent hunger - theoretically making it easier to lose weight. By limiting the calories in your meals, you can lose weight via calorie restriction.

Despite its convenience, nutrition experts do not recommend this diet. The Nutrisystem diet has both practical and health-related drawbacks. Cost: Like many commercial weight loss plans, Nutrisystem won't fit into everyone's budget.

While Nutrisystem does state that its meals offer balanced nutrition, combining lean proteins, healthy fats, dietary fiber and “smart” carbohydrates, the program seemed to focus more on a calorie deficit and less on a holistic approach to nutrition.

Cons. Cost: Nutrisystem can cost $200–$350 per month, and a person still needs to purchase some food, such as some fruits and vegetables. Processed meals: Although the company aims to support weight loss and blood sugar management, most of its options are highly processed.

Nutrisystem meal plans are healthy in that the portion control helps provide a minimal number of calories to support weight loss, and meals are designed by nutritionists and dietitians to be in line with nutritional guidelines set forth in the 2020-2025 Dietary Guidelines for Americans.

Overall the diet is healthy for people with conditions like heart disease, high blood pressure, high cholesterol, and diabetes. Meals are low in sodium, saturated fats, and trans fats, and include high-fiber whole grains, smart carbs, healthy fats, lean protein, and a wide variety of foods.

Today, Nutrisystem is still helping people lose weight with its frozen and nonperishable meals, snacks, shakes and desserts.

The Nutrisystem diet allows lean protein, healthy fats, low-fat dairy products, nonstarchy vegetables, certain fruits and whole-wheat carbohydrates. The program doesn't encourage sugary desserts, high-calorie meals, deep-fried foods, butter, starchy vegetables, such as potatoes, and sugary drinks.
