Intermittent fasting is an eating pattern where you alternate between periods of eating and fasting. It doesn’t specify which foods to eat but focuses on when you should eat them. Popular methods include the 168 method (fasting for 16 hours and eating within an 8-hour window) and the 5:2 method (eating normally for 5 days and restricting calories for 2 days). Intermittent fasting can help with weight management, improve metabolic health, and simplify meal planning.
