True Star. It balances your fat, protien and carbs and limits some stuff like pop to off limits. I lost 40lbs over one summer and have kept it off. The first 2 days I was hungry, because I am a big boy. I added a snack or 2 and was fine after that.
The first week or so I had to weigh stuff, but after that I knew how much food I was supposed to eat. The biggest thing I learned from True Star was just how much my body needed. When I was growing up, I never learned about when to stop eatting or how much you should be eatting. Now I know.
