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

In: Biology

Answer 1

It’s a way of approaching CICO (calories in calories out). If you can pick a time of the day where you don’t like to eat, then skip the meal. You’re unlikely to match the calorie intake with the remaining meal(s), so less calories in, but without a huge loss of quality of life (you didn’t like to eat at the tine anyway).

It works very well if you skip some garbage food you just felt obliged to it.
