Intermittent fasting (IF) is a dietary approach that results in a metabolic shift from using glucose to fatty acids or ketones as fuel for all body functions.
IF has gained more and more attention in recent years.
Intermittent fasting is a broad term that encompasses a variety of programs that manipulate eating practices to include short periods of fasts with the goal of improving overall health. While this dietary practice dates back to the hunter-gatherer period, fasting was also used by civilizations including the Greeks, Romans, and Chinese for medicinal purposes.
Interestingly, there are a number of religious entities that continue to practice fasting including Christianity, Buddhism, and Islam.
