After 72 hours of fasting, your body undergoes significant changes. Autophagy, the process where cells break down and remove dysfunctional components, is heightened, improving cellular health. Insulin levels drop, allowing fat stores to be used for energy, supporting weight loss. Growth hormone levels increase, aiding muscle preservation and fat metabolism. However, prolonged fasting should be supervised by a healthcare professional to ensure safety and address any potential health risks.
FAQs & Answers
- What is autophagy and why does it increase after fasting? Autophagy is the process where cells clean out damaged components. It increases after fasting because the body activates cellular repair mechanisms to improve health.
