The video explores the profound effects of fasting on your body over various durations, ranging from 12 hours to 72 hours ⏳. It highlights the remarkable biological processes activated during these fasting periods, underpinned by scientific principles and human evolution.
Initially, at around the 12-hour mark, your insulin levels start to drop significantly. This decline signals your cells to access stored energy instead of relying on incoming nutrients. The liver begins by releasing glycogen to maintain stable blood sugar levels. As a result, muscles and fat tissues prepare for a shift in fuel type, relying more heavily on fat instead of glucose, promoting fat burning and energy efficiency.
By 24 hours, your body depletes its glycogen reserves and begins producing ketones, ensuring your brain remains fueled even in the absence of food. This metabolic transition is crucial for energy management and cognitive function.
When fasting extends to 48–72 hours, autophagy ramps up dramatically. This process involves the removal of damaged cellular components, enhancing cellular repair and longevity. Moreover, inflammation decreases, and mitochondrial efficiency improves, which contributes positively to overall health. Your immune system undergoes a reset during this phase, optimizing its responses and enhancing resilience against chronic inflammation.
Overall, fasting isn’t merely a practice of deprivation; it’s a method of activating ancient survival mechanisms encoded within our DNA. The subsequent energy boost, mental clarity, and improved metabolic health are among the many benefits that can be derived from intentional fasting.
