The Fast

With fasting at an all-time high in popularity, here is the first deep exploration into the surprising history and science behind the practice-essential to many religions and philosophies.

Whether for philosophical, political, or health-related reasons, fasting marks a departure from daily routine. It involves doing less but doing less in a radical way. Based on extensive historical, scientific, and cultural research and reporting, The Fast illuminates the numerous facets of this act of self-deprivation. John Oakes interviews doctors, spiritual leaders, activists, and others who guide him through this practice-and embarks on fasts of his own-to deliver a book that supplies readers curious about fasting with profound new understanding, appreciation, and inspiration.

Notable fasters include Moses, Buddha, Jesus, Muhammad, Gandhi, George Washington, Abraham Lincoln, Emily Dickinson, Mark Twain, Cesar Chavez, and a long list of others who have drawn on its power over the ages and across borders and cultures.

The Fast looks at the complex science behind the jaw-dropping biological phenomena that occur inside the human body when we fast. Metabolic switching induced by fasting can prompt repair and renewal down to the molecular level; such fasting can provide benefits for those suffering from obesity and diabetes, cancer, epilepsy, cardiovascular disease, neurodegenerative disorders, and more. Prolonged fasting can serve both to reinvigorate the immune system and to protect it against damage.
