Wildcard...just an observation here, but if you're going to a) follow a low carb diet and/or b) discuss one, it might benefit you to actually read about the science behind them first, not just what the media has to say about it.
It seems, as someone else has already observed, that you don't completely understand or appreciate the role that insulin as well as several other hormones that are directly influenced by insulin, have on weight gain and loss.
If I might suggest, Protein Power by Drs. Dan and Mary Eades gives an excellent overview on the subject.

Lisa N, I could not have said it better myself. The media has made this diet the controversey that it is. I love the Protein Power. I have more knowledge about the human body than the la dee da media and perhaps as much as some doctors.

Wildcard, if you do not read any low carb books the only thing that you will be is clueless. You cannot agree or disagree on something that you know nothing about, in all respect.
