There are many sites offering guidance on the use of low-carbohydrate high fat diets. Atkin's type diets or more correctly ketogenic diets. I have not had a chance to read any of these in depth, but all the ones listed seem on the surface to provide sensible information.
Ketogenic Doctors

Warning Dr. Jack Kruse is very controversial. He talks about the mitochondria in your cells producing "light", when most people would say energy. I don't know what to make of him. I challenged one of his statements on a "Nutrition" forum a few months back, and he went to a lot of trouble to give me a pretty good reply, showing that, as far as I can tell, I was wrong. Nobody else on the forum was prepared to challenge what he said.
