Question

What is the fundamental science behind the idea of “Intermittent Fasting” and how does it work?

In: Biology

Answer 1

Weight loss is about calories in vs calories out. By limiting eating to set hours, calories in are restricted. As such, intermittent fasting is an effective method of weight loss. Relative to other calorie restriction systems, it may be easier to adopt since a practitioner can eat “whatever they want” during eating hours.
