Hi snowgal, welcome to 3FC!
Maybe Calogel has changed their formula since the last time you used it. More than likely, though, it was the South beach diet that did the trick, since it's a really good weight loss diet. I just checked the ingredients for Calogel and I don't see anything in there that should help weight loss. It has CLA which has been shown to help keep weight off, but not to help take it off. The other ingredients have not been shown to help, either. They always say otherwise, of course, but that's just the way the market is. Generally speaking, any product that claims you can just take it and lose weight while you sleep is a good sign of a scam. It takes a good diet and exercise plan to take weight off and keep it off.
Have you considered going back on the South Beach diet, or another diet plan? The Sonoma Diet is gaining in popularity, it might be worth checking out.
