NutriSystem has been providing dieting solutions for over 35 years, and topped last year's Fortune 100's list of fastest-growing companies. The cornerstone of the NutriSystem plan is its low-glycemic, low-fat suite of prepackaged foods (NutriSystem Nourish foods) that are filled with good carbs and healthy portions of protein and fiber. The success of this plan can be attributed to the ease and convenience of ordering the prepackaged NutriSystem Nourish foods online, which is delivered within a few days right to your doorstep.

What's so good about NutriSystem?

So why? Why are so many people embarking on this diet?

The NutriSystem Nourish program is all about convenience. They sell pre-packaged (heat and eat) meals from their website and ship them to your door. They have an ongoing deal that will supply one weeks free food with every 4 week order (see the free deal here). This amounts to $280 for 5 weeks food. In an age where foods are chosen according taste, price, and convenience - it should come as no surprise that Nutrisystem is so popular. This is effectively fast food for weight loss. If you are not prepared to eat processed food (i.e. increased sodium), then this is not for you.

With the autoship option, the price gets cheaper each month, going from $280, to $270, to $260 and so on.

Jenny Craig vs Nutrisystem

Both of these diets are about pre-packaged foods and portion-controlled weight loss. Jenny Craig charges a membership fee (which requires signing a contract). Nutrisystem has no such contract and membership is free. Jenny Craig allows you to visit with a counsellor, whereas Nutrisystem only offers phone counselling.
