The Body Book: The Law of Hunger, the Science of Strength, and Other Ways to Love Your Amazing Body

Daily Beast calls Diaz's message "smart. Your body is the best instrument you’ll ever own." From the publisher: "The Body Book does not set goals to reach in seven days or thirty days or a year. It offers a holistic, long-term approach to making consistent choices and reaching the ultimate goal: A long, strong, happy, healthy life."
