Michael Mosley meets Joe, a Cronie. A Cronie is someone who subscribes to the CRON diet (Calorie Restriction with Optimal Nutrition). A healthy diet which is rich in nutrients but low in calories. Michael and Joe take part in some medical tests to assess their health and relative aging, with some shocking results.
Michael Mosley has set himself a truly ambitious goal: he wants to live longer, stay younger and lose weight in the bargain. And he wants to make as few changes to his life as possible along the way. He discovers the powerful new science behind the ancient idea of fasting, and he thinks he's found a way of doing it that still allows him to enjoy his food. Michael tests out the science of fasting on himself - with life-changing results.
