Intermittent fasting has become a popular trend in health and wellness circles. But what exactly is it, and why are so many people talking about it? Intermittent fasting involves cycling between periods of eating and fasting. Unlike traditional diets, it doesn't focus on what you eat but rather when you eat. This eating pattern can help with weight loss, improve metabolic health, and even extend lifespan. People often choose from various methods like the 16/8 method, where you fast for 16 hours and eat during an 8-hour window, or the 5:2 method, which involves eating normally for five days and restricting calories for two days. Curious about how this works and its benefits? Let's dive into 37 fascinating facts about intermittent fasting!
