What Is Intermittent Fasting?

Intermittent fasting (IF) is an eating practice that cycles between phases of fasting and eating. In fact, this eating pattern doesn’t identify which foods one should eat but rather when one should eat them. The most common IF methods comprise daily 16-hour fasts or fasting for 24 hours, twice per week.

Yes, we all know that fasting has been a practice in human evolution. Humans evolved to be able to carry out the normal activity without food for an extended duration of time, as there was no food available year-round or couldn’t find anything to eat. Fasting from time to time is more natural than eating 3-4 meals per day. Also, fasting is observed often for religious and spiritual reasons.
