What is Intermittent Fasting?
Intermittent fasting (IF) is not a diet but an eating pattern that cycles between periods of fasting and eating. It doesn't specify which foods to eat but rather when you should eat them. The most popular methods involve 16-hour fasts or fasting for 24 hours, twice per week.
