1. Can't go wrong with Berardi
2. I also like all of Lyle McDonald's books (specifically
The Ketogenic Diet and
A Guide to Flexible Eating).
3. DiPasquale's "
Anabolic Solution" has some good info.
4.
Natural Hormonal Enhancement by Rob Faigin is a GREAT read.
5.
BodyOpus by Dan Duchaine is pretty much the precursor to most of McDonald's stuff (as well as any targeted ketogenic diet).
Not a big of fan of Susan Kleiner at all. I wouldn't recommend her books.
