In this video, I explain what really happens inside your body during fasting. From 12 to 48 hours, your body shifts from glucose to fat burning, produces ketones, activates autophagy (cellular cleanup), and improves metabolic flexibility. We also cover insulin, growth hormone, digestion, and common myths like muscle loss. Learn how intermittent fasting works, its benefits, and how to start safely with proper hydration and electrolytes. This is science-based education, not a prescription.
