(outlink) Body Recomposition - Lyle McDonald

I've forgotten to make recommendations for where to get good info on dieting. Body Recomposition is Lyle McDonald's website with all manner of background info, including e-books. He's one of the best researchers in the area. If you're into ketogenic diets - going into ketosis a la Atkins - his The Ketogenic Diet - A Complete Guide for the Dieter and Practitioner is the best resource I know of. Beware, though - it keeps the details in place, including a ton of figures and references. Not for the faint of heart.

If you really want to crash diet - losing weight quickly instead of letting it fall off at the body normal pace of 0.5lb per week - his techniques are the best I know of. I personally prefer slow dieting through lifestyle changes, though.
