Ajay, why are you so defensive about the Atkins diet?
It will certainly work, although as people reported here, keeping the weight off long term is a problem. The effects of eating an unhealthy diet (nobody says all that animal fat in Atkins is healthy) and the possibility of kidney problems aren't worth it IMO.
My wife and I changed the way we eat back at the end of April. The only book I read was by Walter Willett, MD and the advice in his book is to exercise, eat less overall, and eat healthy. I don't eat much protein, and I do eat carbs, just whole grains. I've lost 35 pounds and the beauty of it is that I can eat this way forever, not just for a diet period, which is the true downfall of any diet. If you don't make permanent changes, you won't have permanent weight loss.
