Dr Michael Mosley doesn’t just talk the talk, he walks the walk. When the BBC host and champion of intermittent fasting started seeing new research about the benefits of an 800 calorie a day diet, he gained weight just to see if he could lose it with this new approach.
He says 800 is the magic number to trigger changes in the metabolism that produce real health benefits . He shares the science behind the diet and tricks to stick with it in his new book called The Fast 800: How to Combine Rapid Weight Loss and intermittent Fasting for Long Term Health.
