The Fast Diet is a revolutionary new diet that allows you to eat normally five days a week and then fast (consuming 500 calories/day for women and 600 calories/day for men) for two consecutive days. This groundbreaking plan has been wildly popular in the UK and at the time of this show is the No.1 overall best-selling book on Amazon.com. The creator and author of The Fast Diet, Dr. Michael Mosley, joins us for this episode of The Fitness Buff.
