Intermittent fasting (IF) is an eating pattern that cycles between periods of eating and fasting. Common methods include the 16/8 approach, where individuals fast for 16 hours and eat within an 8-hour window, or the 5:2 method, which involves eating normally for five days and restricting calories on two non-consecutive days. This approach can promote weight loss, improve metabolic health, and enhance cellular repair processes. By allowing the body to enter a fasting state, intermittent fasting can also support improved insulin sensitivity and decrease the risk of chronic diseases.
