INSTANT NEW YORK TIMES BESTSELLER * USA TODAY BESTSELLER * WALL STREET JOURNAL BESTSELLER Learn how to reboot your metabolism build strength and extend your life with this accessible new guidebook that demonstrates the importance of muscle for health and longevity from the founder of the Institute for Muscle-Centric Medicine(R). After years of watching patients cycle through her practice Dr. Gabrielle Lyon noticed a pattern. While her patients struggled with a wide range of conditions they all suffered from the same core problem: they had too little muscle rather than too much fat. When we think about muscle we tend to think about strength or aesthetics but in reality muscle accounts for so much more than that. As the body s largest endocrine organ muscle actually determines everything about the trajectory of health and aging. Many of the conditions Dr. Lyon s patients were experiencing were actually symptoms of underdeveloped or unhealthy muscle. Now Dr. Lyon offers an easy-to-follow food fitness and self-care program anchored in evidence and pioneering research that teaches you how to optimize muscle--no matter your age or health background. Discover how to overcome everything from obesity to autoimmune disorders and avoid diseases like Alzheimer s hypertension and diabetes by following Dr. Lyon s powerful new approach to becoming forever strong.
