Intermittent fasting has emerged as one of the most popular health trends worldwide. It involves alternating cycles of fasting and eating, providing numerous health benefits, including weight loss, improved metabolic health, and potentially increased longevity. This comprehensive guide explores six proven methods of intermittent fasting, tips for success, potential risks, and answers to frequently asked questions. Let’s dive into the details.
