The only catch? You have to fast two days a week. More specifically, on two non-consecutive days, you must reduce the number of calories you normally enjoy by 25%. That’s approximately 500 calories a day for women, and 600 calories for men. While the weight-loss claims may sound impossible, the diet, which is also known as “5:2” or alternate day fasting (“ADF”), is actually gaining credibility with some researchers and medical professionals, and several new studies suggest it works. Still find the 5-day gorgefest and 2-day starvation protocol a little hard to swallow?
