Intermittent fasting is an eating plan that is focused not on how much you eat or what kind of food you eat — as is the case with most diets — but on when you eat. An intermittent-fasting plan involves going without food for a set number of hours each day, or greatly reducing what you eat on one or two days a week. It is one of the most popular diets in the US, though it’s worth noting that some proponents consider it an eating pattern, or even a lifestyle, rather than a diet.
Disclaimer: It's a good idea to check with your doctor or dietician before trying intermittent fasting or dramatically changing your diet.
