The mother of one of my daughter's childhood friends was on it and I didn't know it. I hadn't seen this woman in ages and one day drove by her house and she was outside and I thought it was her daughter. She had lost 100 lbs.! It took her a couple of years but she told me she is still in a maintenance program and has not put any of it back on. She looks and feels wonderful. Good luck to you! I think if I was to go on a program this is the one I would choose!
