Intermittent fasting (IF) is an eating schedule which alternates between fasting and feeding. You set a time window for eating, eat only within that window and fast the rest of the time.

For example, you may eat only between the hours of 10:00 AM and 6:00 PM.

IF is not a diet in the conventional sense, but rather, a pattern of eating.

Certain types of intermittent fasting can be incorporated daily, while others are meant only for longer blocks of 3 to 5 days.

Each style carries its own benefits for metabolism, disease prevention, cellular repair and psychological well-being. In this guide, we’ll go through all of the benefits, ways to do intermittent fasting and frequently asked questions.
