The idea of intermittent mini-fasting seems to be gaining traction. One version of the diet is being popularized by Michael Mosley, a British physician and journalist who’s written a best-selling book called The Fast Diet and produced a documentary.
And there are other popular tomes on the topic. Take for instance, The 5:2 Diet Book, which claims you can boost your brain power and transform your health by feasting for five days and fasting for two.
About 100 women, all of them overweight, were asked to follow a diet in which, for five days a week, they followed a Mediterranean diet pattern of eating. The other two days, they ate a low-calorie diet of lean protein and cut out almost all carbohydrates.
At the end of the study, the women on this 5-2 diet lost significantly more weight compared to women who’d tried to restrict calories all week long. And in addition, their insulin resistance improved.
