I'm currently on the Nutrisystem diet and I love it. The food is good (it's just really portion controlled) .I've been on it before when I first had my kids. I've lost 5 lbs. in the first 1.5 weeks!
Since they have several discounts the food is fairly reasonable. They currently have a week free when you order the 28 day order. So that makes it 5 weeks of meals. The regualr price is $329 but if you order the "autoship" where they ship your order automatically every month, you get free shipping and the order gets down to 289. That's not bad when you think about losing weight, not really cooking breakfast lunch dinner, snacks. All you add is fruit and salads and dairy.
Also you can change the autoship program back 45 days and then cancel altogether if you don't plan on re-ordering.
I'm an accountant so I "run numbers" for everything (lol)! Let me know if I can help in any way!
