Intermittent fasting (IF) is a dietary approach that alternates between periods of eating and fasting. It can significantly affect weight management by promoting caloric deficit, leading to fat loss. During fasting phases, insulin levels typically decrease, enhancing fat oxidation and improving metabolism. IF may also increase human growth hormone (HGH) levels, which can enhance muscle preservation during weight loss. Additionally, this method can simplify eating routines, making meal planning less complex. However, it's essential to approach intermittent fasting mindfully, ensuring balanced nutrition during eating windows to support overall health.
