Writing about nutrition and fitness is what Dr. Berardi loves most. He's written countless articles for nearly every site or magazine that covers nutrition. He's written a comprehensive nutrition program called The Precision Nutrition System. A cookbook for the fit food lover called Gourmet Nutrition. And the definitive textbook on nutrition science for fitness professionals called The Essentials of Sport and Exercise Nutrition.
Over his career, Dr. Berardi has personally coached and consulted with thousands of people from all walks of life. From everyday people who could be your neighbors, right up to athletes at the highest level of sport. He currently leads the extraordinary coaching team at Precision Nutrition and co-developed Precision Nutrition Coaching, which broke ground as the first entirely web-based nutrition coaching system. PN Coaching is beloved by clients and consistently helps people get healthier, stronger and fitter than they ever thought possible.
