Here's two links - the book on Amazon (
http://www.amazon.com/Doctors-Quick-.../dp/0132168790) and the wiki entry on it (
http://en.wikipedia.org/wiki/Stillman_diet).
Stillman is basically a low fat version of Atkins. I personally think that probably most folks over 250 lbs really would not need to go on it. It's extreme. And if you have that much weight to lose, a more traditional diet should work just fine.
I have already lost over 150 lbs and my body has become resistant to most forms of dieting. I had to go to something extreme in order to jumpstart, and keep, losing. I went on Stillman August 1st and I lost 10 lbs in less than 2 weeks, 225 to 215. I keep my calories at 500-700 per day, carbs at about 4 grams. The first week I felt weak, no energy, and had severe "Atkins flu" but now I feel normal and although the scale has again quit moving I keep trying on unforgiving clothes and they get a bit looser every couple days. So I know I'm getting smaller if not lighter.
I do not recommend Stillman for long term, or for anyone who can lose on any other diet. Atkins is a much better choice for most folks. I just need to do it for now since Atkins quit working for me. My personal opinion is, calorie counting is great, probably the best diet, if there is such a thing, and if it works for you, do it. If carb counting works for you - it did for me, for a long time - great, do that. Do whatever works. But don't do anything extreme unless you HAVE to because it's very difficult to sustain over the long haul. And the last thing you want to do is gain it all back.
