I do a combo of South Beach and Atkins and was not a happy camper when I started back with my Firm work outs with heavy weights and lots of cardio (in place of the stationary bike) and saw the scale go up. It took about a six weeks for my weight to stabilize and then start going back down but I've lost an incredible amount of inches since I stepped up my work outs. As the previous poster said, the combo of diet and exercise can't be beat for success in the long run. Now start measuring so you can see the inches flying off!!!
