Intermittent fasting (IF) is not a specific dietary type but a pattern of eating. Intermittent fasting doesn’t change what you eat, it changes when you eat. Most of the time people who follow IF use a 16–hour fast followed by an 8–hour eating period. It doesn't matter when you start your 8–hour eating period so you can work this around your lifestyle. For example, most people do their 16-hour fast overnight into the morning and therefore don’t eat breakfast. During the 8-hour eating period they eat their lunch and dinner as these are usually the meals they would eat with friends and family. One of the best ways to get started with intermittent fasting is to do it once per week and then build up to doing it every day.
