📋 Quick Summary
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It does not specify which foods to eat, but rather when to eat them. The most popular method is 16:8 — fasting for 16 hours and eating within an 8-hour window. Other common methods include 18:6, 20:4, 5:2, and OMAD (One Meal a Day).
