Run Your Butt Off! is founded on the simple concept that in order to lose weight, calories burned must exceed calories consumed. No gimmicks or shortcuts can circumvent that weight-loss reality.

This book shows readers how to shed unwanted pounds by approaching both sides of the weight-loss equation—the calories in and the calories out—at the same time. Leslie Bonci, a renowned sports dietitian, offers a step-by-step guide to painlessly cutting caloric intake through better nutrition choices and improved shopping and cooking habits. Budd Coates, a competitive marathoner who has coached thousands of beginning runners, offers an easy way to boost metabolism with a walking and running schedule designed to steadily change a sedentary lifestyle into an active one. Together, the results are fast and satisfying. With Run Your Butt Off!, you'll be on your way to permanent weight loss.
