April 3, 2024

Embarking on a 3-day water-only fast triggers significant physiological changes in the body, affecting various systems including the brain and respiratory system. The body begins to utilize stored energy reserves, leading to a decrease in blood sugar levels and insulin production. This metabolic shift prompts the liver to produce ketones, which serve as an alternative fuel source for the brain, potentially influencing cognitive function and mental clarity. Additionally, the process of autophagy, wherein the body breaks down and recycles damaged cells, is initiated, offering potential benefits for cellular repair and longevity. Furthermore, the act of deep breathing during fasting may induce a state of relaxation and heightened mindfulness, contributing to overall well-being.
