It basically does what it says on the tin: you eat properly for five days of the week and fast for two; on a fasting day, women are recommended to consume just calories.

Dietary restriction can cause eating disorders in people with these risk factors, he adds, and studies have associated fasting with a higher risk of bulimia in particular. The good news is, you can take active steps to keep hunger in check. During fasting periods, avoid looking at, smelling, or even thinking about food, which can trigger the release of gastric acid into your stomach and make you feel hungry, says Yuan-Xiang Pan, an associate professor of nutrition at the University of Illinois at Urbana-Champaign.
