Using the latest in medical imagery and a tiny state-of-the-art “camera pill” he swallows at the start of the film, Mosley takes viewers on a remarkable journey, revealing his innards as they digest his food. At each stage, he talks to medical experts and explains the amazing functions that occur without conscious effort.

Among the discoveries is an intricate “second brain,” present in the intestines, that comprises millions of neurons to orchestrate digestion and may explain the concept of “a gut feeling.”

Mosley also learns how fecal transplants increasingly are being used to treat serious stomach and bowel disorders, and visits a gastroenterologist to discover a fascinating relationship between personality types and pain responses.

A new book, "The Fast Diet: Lose Weight, Stay Healthy, and Live Longer with the Simple Secret of Intermittent Fasting" by Dr. Michael Mosley and Mimi Spencer, which was written after Mosley filmed this special, is available from Atria Books. After broadcast, the book also will be available at ShopPBS.org or 800-PLAY-PBS.
