I think this is the best diet information available. I had read fit for life a few years ago and followed that for a while and put on some weight, I tried high protein diets and put on weight. I became a vegetarian and followed fit for life again and put on a lot of weight. I had read about how vegetarians were all skinny but the book never mentioned that eating oil, nuts, tofu, and peanut butter would cause weight gain. I picked up this Mcdougall book in September 1998 at a weight of 183 pounds (at 5"6). I followed it to the letter (except that I drink lots of black coffee) and I went down to 140 pounds in 4 months. I find it very easy to follow although I have not gone to any restaurants since I started which would be difficult. It is also important to mention that during this time I was eating huge quantities of the required foods and I had no time to excercise; so there was absolutely no deprivation whatsoever. I'm still on the diet and have had no cravings for high fat foods or animal products. I've never felt better.
