What is Intermittent Fasting?
Intermittent fasting (IF) is an term for cycling between a period of fasting and non-fasting. Many common fasts are 16:8 (sixteen hour fast with an eight hour eating window) and 18:6 (eighteen hour fast with a six hour eating window).
Intermittent fasting (or meal frequency) in itself does not promote weight loss, but caloric balance does. However, many proponents of IF find the strategy helps to manage their hunger with low calories while dieting.
