Nutrisystem was created in the 1970s by Harold Katz. The entrepreneur was living on a liquid-based diet for weight loss. While this method worked to some degree, Katz realized people want to eat real food. He spent years tweaking his system in order to help people feel sated, enjoy their food, and lose weight.
What Katz realized—what has made Nutrisystem successful in helping people lose weight for nearly five decades—is that people need personalized plans. Nutrisystem is a diet plan service with a variety of pre-packaged, ready-to-eat food, delivered at your door. The menu includes everything from burgers, pizzas and pasta to chocolate desserts and beverages. However, everything is provided following a plan of portion control and healthy eating.
