Dr Mosley's Fast Diet has become the health phenomenon of our times. And for good reason. This radical approach to weight loss really is as simple as it sounds. You eat normally for five days a week, then for just two days you cut your calorie intake (600 for men, 500 for women). In this fully revised edition, Michael Mosley introduces the science behind the diet, with exciting new research into the wider health benefits of intermittent fasting including studies on asthma, eczema and diabetes.
