A lot of the weight loss talk has been about me b/c I'm making myself accountable by doing it publicly. That helps me a lot, even though this is just people on a web forum, there are still people out there that know I'm doing it and are cheering me on as I keep going down. Weight Watchers has been very successful for me so far (down a little over 24 pounds in 9 weeks), and it was for my mom in the past. I like that on Weight Watchers you can still allow yourself those "indulgences" that you love, so you can still have beer on Weight Watchers, you just have to count the points.
I can't say that I know the exact formula, I know that there is a fine line between over feeding yourself and giving your body enough food to run without thinking it is going into starvation mode.
Good luck to you, this forum is great on supportiveness
