The 7 Principles of Stress

Extend Life, Stay Fit, and Ward Off Fat--What You Didn't Know about How Stress Can Reboot Your Mind, Energy, and Sex Life

Harness the power of beneficial stress for enhanced fitness, anti-aging, and longevity with this cutting-edge health and wellness research

Ori Hofmekler, acclaimed author of The Warrior Diet and one of the first proponents of intermittent fasting, challenges conventional wisdom about diet, fitness, and anti-aging with a new approach to health that uses stress to live longer, stay fit, and ward off fat. Supported by cutting-edge research, this book redefines the term "nutrition" as it reveals the stress-mimicking nutrients that yield the same benefits as fasting and exercising.

At the core of the book is the biology of stress and the way it affects key aspects of life from feeding and sexual behavior to mental and physical performance. Hofmekler demonstrates that that there is a thin line between beneficial stress and harmful stress, and shows how to put knowledge of the difference into powerful practice. His book is a call to action—a manifesto of living life to its utmost evolutionary potential, under stress, as nature intended.
Ori Hofmekler is the author of The Warrior Diet and the first to introduce the concept of intermittent fasting in practice.  A native born Israeli, he graduated the Bazalel Academy of Art and the Hebrew university where he earned a degree in Human Sciences.  Hofmekler's formative military experience prompted a life interested in survival science and the biology of stress, all of which inspired him to pioneer a new area of research known as stress activated food (SAF).  The SAF project was initiated in collaboration with a group of scientists and scholars to investigate the impact of nutrients in stressed food on the health and life-span of the consuming organisms. Hofmekler has been since working on new research projects which he believes can help utilize this data to further understand the dynamics of stress and improve life. Hofmekler's previous books include The Warrior Diet (2002, 2007), Maximum Muscle Minimum Fat (2003), The Anti-Estrogenic Diet (2006), and Unlock Your Muscle Gene (2011).
