I think that out of everything I've tried (and I have tried just about EVERYTHING) WeightWatchers is the best. My mom joined when it was still free and the points system was just starting out. The best part is, you can eat whatever you want! Just budget what you eat so you don't go over your points. Like, if you want a Grilled cheese sandwich and chocolate cake, you can have it, it just cost you 20 points though. So, if you are allowed 24 points a day, you only have 4 points left ot eat foods worth 0 points (like veggies and salad). It's easy, if you can add, you can do it. Mostly, it's common sense and eating in moderation, only tailored into a better system for people like me. It really does work.
