Query: Excellent reference-combines basic science and how to's.

This is a well written, well referenced, and unbiased book on diet and exercise. The basic science is comprehensive but easily understood. The practical recommendations based on the science, and the authors own experience, have made a huge difference in my own dieting results. Any dieter can gain a better understanding of metabolism by reading this book. It should be considered mandatory for anyone serious about using exercise (esp. weightlifting)and diet to change body composition.
