I haven't posted on their boards, no, but I've actually had a lot of success with them...until I gained it all back...every single time. It's a good program, IMO, but it doesn't work for everyone.

If you think you can eat with that large of a deficit of calories for that long and lose all of your weight without surgery, go ahead. As for me, I'll stick to my band. :welldoneclap:
