Diets Debunked

The idea is that can help people lose weight reduce the progression towards age related diseases such as cancer and even add years to your life.

Evidence

There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective, which has been confirmed by the metabolic experts at the Massachusetts General Hospital and Harvard Medical School. There is some good scientific evidence suggesting that circadian rhythm fasting, when combined with a healthy diet and lifestyle, can be a particularly effective approach to weight loss, especially for people at risk for diabetes. (However, people with advanced diabetes or who are on medications for diabetes, people with a history of eating disorders like anorexia and bulimia, and pregnant or breastfeeding women should not attempt intermittent fasting unless under the close supervision of a physician who can monitor them.)

Evidence
