Nutrisystem food is sold by a week’s supply, or a month’s supply. Usually offers are made for discount if you select "autoship" for regular monthly shipments without reordering. If you order directly from Nutrisystem’s website, you can choose your meals. However, you can also buy Nutrisystem food from a variety of vendors online, which is less expensive, but you get a package of food that has been pre-selected and do not have the priviledge of choice. Each shipment includes breakfast entrees, lunch entrees, dinner entrees, and dessert entrees. Mind that you have to supplement the Nutrisystem food with dairy products, salads, vegetables, and fruit. You also have to drink a minimum of eight glasses of water a day.

Nutrisystem offers a wide variety of entrees to suit a wide variety of tastes. Breakfasts can be a choice of several types of cereals, eggs, muffins, oatmeal, pancakes, or granola bars. Lunches can range from a variety of soups to Fettucini Alfredo to Veggie Sloppy Joes, and also includes Chicken or Tuna Salad. Dinner choices range from Italian dishes like Ravioli, Lasagna, or Pizza to beef dishes like Beef Burgandy, Beef with Orzo Pasta, Beef Stroganoff, or a Cheeseburger. There are also many chicken dishes, including oriental or Cajun and even dishes that are strictly vegetarian. Variety is not a problem.

The entrees do not require refrigeration, so they are very portable to take to work. Most are just heated in the microwave, or cooked by adding boiling water, and some are ready to eat as they are. Only a few have any cooking at all involved, like pancakes.
