How Fasting Works The 5 Key Stages of Metabolism During Extended Fasting
In this video, we explore the five stages of fasting and the physiological changes your body undergoes as you fast. From the initial feeding stage to long-term fat-burning ketosis, fasting is more than just a weight-loss method—it’s a powerful process that can promote metabolic health, improve mental clarity, and support cellular repair. We dive into the science behind fasting, covering the shift from glucose to fat as your body's primary energy source, the activation of autophagy for cell renewal, and how ketosis boosts brain function and fat loss. Learn how fasting impacts hormones like insulin and cortisol, and discover how the body adapts at different stages to conserve protein and improve overall well-being. Whether you're fasting for health, weight management, or cognitive benefits, understanding these stages is key to unlocking fasting's full potential. We also discuss the critical role of glucose and fat as the body's primary fuel sources, the importance of insulin sensitivity, and how autophagy helps with cell regeneration. Gain valuable insights into safe and effective fasting practices that optimize your body’s energy usage. Join us to understand the science behind fasting and learn how it can benefit your health and longevity!
