Weight Watchers is a point system. They have foods in the grocery store that you can buy that are less in points. For example- A regular Thomas' English Muffin would be 3 pts when a Weight Watchers English Muffin would only be 1 pt. There are differences in the taste of most things but nothing too drastic. My sister was on Weight Watchers and I tried all of their foods and they weren't that bad. The difference in this diet compared to others is hard to say. You would have to be more specific as to which diets you want to compare it to. I'll just compare it to Nutri System for now. Nutri System also has its own food. There aren't any points to count just a certain amount of meals per day and their portions- which are small. That has better results though. My aunt lost 10 lbs in a little over one week. She's losing a lot fast- its amazing. Its a lot more expensive though too.
