Intermittent fasting is an eating pattern that alternates between periods of eating and fasting. It does not prescribe specific foods but focuses on when to eat. Common methods include the 16/8 method, where individuals fast for 16 hours and eat during an 8-hour window, and the 5:2 diet, which involves eating normally for five days and restricting calories on two non-consecutive days. This approach is believed to offer various health benefits, such as weight loss, improved metabolism, and better blood sugar control. However, it may not be suitable for everyone, and individuals should consult a healthcare professional before starting any fasting regimen.
