Beyond the fad weight-loss diets, beyond the bodybuilding mythology about excessive amounts of protein for making muscle, beyond the nonsense that circulates about nutrition in the world today, there is a body of scientific knowledge that shows us a road map to our goals. For example, Susan Kleiner shares a formula to determine exactly how much protein the bodies of strength trainers and bodybuilders can use before storing the extra as fat, why amino-acid supplements are a very expensive and somewhat inferior substitute for simple foods such as yogurt and chicken, and why carbohydrates, not protein, are the most important nutrients for muscle building. Many of the recommendations seem so simple--"eat fruits and vegetables," for example--but Power Eating shows us that sometimes the oldest advice in the world is perfectly aligned with modern nutritional science, whereas the complex solutions dreamed up by bodybuilding gurus and supplement manufacturers don't always stand up to rigorous analysis.
