I started the plan 3 days ago, and I was very discouraged after reading some of the reviews.  Then for the first full day and part of the second day I was suffering from headaches, and was even more discouraged.  I am glad to report on day 3 - the headaches are completely gone and I have lost 5 pounds!  The food tastes great, and the dinners are so filling that I had to switch lunch and dinner so that I eat my biggest most filling meal in the middle of the day when I am most active.  The lunch portion is just enough for an evening meal.  Then as my bed snack, when I used to religiously have a piece of pound cake and milk, I now have a chocolate chip or oatmeal raisin cookie with a couple of ounces of skim milk.  Its perfect!  I still cook for my daughter without incident.  I think this plan is much better than LA Weight Loss (that didn't teach portion control - just kept you hooked on their bars so that when you no longer bought these expensive little crutches, you gained all the weight back), Weight Watchers (which takes forever to lose a pound), & Jenny Craig (which is so expensive - when you're done you won't have any money left to buy new clothes that fit).   I've tried them all, and speak from experience.  I'm very happy with NutriSystem!
