Key Points

  • Fasting is a biological rhythm hardwired into human DNA, promoting healing, detoxification, and cellular repair during periods without food intake.
  • Insulin levels drop during fasting, triggering fat burning, autophagy, and reducing inflammation, which collectively improve metabolic health and reduce the risk of various chronic diseases.
  • Proper fasting protocols, such as 12-12 or 16-8 windows, paired with adequate hydration and nutrient-rich foods, can optimize health benefits and promote long-term metabolic flexibility.
