I just turned 54, and went on Atkins in Dec 2012. I have lost about 20 lbs. It is much harder now for me to drop weight than it was previously. I just got a wisdom tooth out on Thursday and off the painkillers. I am still on antibiotics, which I think are causing me to retain fluid. Anyway, the Fat Fast has worked for me, I was down to 165, but am sitting at 168 now. Fat Fast is really the only way. I would love to get down to 150 lbs, but this might not be possible.
