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).
