I'm on WW it's just like Melissa said. You get so many points per day depending on your weight. You also get 35 Flex points per week to eat any way you like. You can eat them all at once or divide them up. They are calculated based on the food Calories, total Fat, and fiber. They don't count carbs. For Example I weigh 205 and am allowed 26 points per week and I also get 35 flex points, which I use when me and my husband go out to eat. I was on WW about 2 years ago and lost 63lbs. then I quit doing it and gained it all back. It really does work though....Hope this helps!!
