Dr Prashant Katakol, a neurosurgeon with over 33 years of experience, reveals the effects of a 36-hour fast on the human body. Fasting triggers a shift from glucose metabolism to fat burning, enhancing mental clarity and initiating cellular repair processes. According to Dr Katakol, this structured fasting practice, shared via an Instagram post on October 24, helps the body undergo autophagy, clearing toxins and damaged proteins while stabilizing energy and improving insulin sensitivity.
During the first 6 hours, the body relies on energy from recent meals with glucose levels remaining stable. Between 6 to 12 hours, glycogen stored in the liver and muscles provides energy as hunger slowly builds. After glycogen depletion, fat cells release fatty acids converted into ketones, offering a clean energy source for the brain and organs. Hunger hormones like ghrelin decrease, resulting in alertness and focus.
By the end of a 36-hour fast, autophagy becomes active, reducing inflammation, recycling cellular components, and preparing the body for efficient nutrient absorption. Breaking the fast with a nutrient-rich meal ensures optimal recovery. Dr Katakol emphasizes that fasting is not starvation but a method of structured recovery that supports the body’s natural healing.
