Intermittent fasting (also called alternate day fasting) has become a popular diet.

In most versions of intermittent fasting, people fast or eat very little a few days each week and then eat normal amounts during the remaining days.

Fasting is something that human beings have practiced throughout history, often out of circumstance rather than choice.
