The Books That Changed The Science
Dr. Portman has co-authored three books with Dr. John Ivy. Their first book, Nutrient Timing, has been called, “the next important nutrition concept in the 21st Century”. Nutrient Timing dramatically changed the role nutrition plays in performance and its principles have been universally incorporated in the training regimen of athletes at all levels. The second book, The Performance Zone, creates a nutrition action plan so that every athlete can utilize nutrition to enhance endurance and raise athletic performance. The latest book, Hardwired for Fitness, uses the latest science to demolish myths that serve as a barrier to getting fit. Hardwired for Fitness shows how, by resynchronizing your body’s natural biologic rhythms, you unleash a powerful arsenal of metabolic weapons to help you get and stay in shape.
