Fasting and the Longevity Revolution travels from tiny villages in Calabria and Sardinia to cities like Milan, Genoa, and Los Angeles, and into the mountains of southern Ecuador to reveal that genetic mutations, fasting, or both can make simple organisms live 10 times longer and protect humans from cancer, diabetes, dementia and heart disease.

British journalist and physician Michael Mosley sets an ambitious goal: to become healthier and lose weight while making as few changes as possible to his life. In working toward these goals, Mosley discovers a powerful new science behind the old idea of fasting, a program that still allows him to enjoy his favorite foods. He takes a road trip across the U.S. to investigate how a little hunger can turn on the body’s “repair genes” and, of course, tries the new science himself. Mosley learns that a diet based on feast and famine has powerful effects on the body, reducing the risks of heart disease, diabetes and some cancers. The diet seems to pack the anti-aging clout of calorie restriction while still allowing for a taste of the good life. And it turns out to be not only good for the body; it may also be good for the brain.
