The Biological Mechanisms of Intermittent Fasting
Intermittent fasting starts important changes in the body that help health and make metabolism better. It changes hormone levels, which helps the body adapt. This leads to benefits like better cell repair and metabolism.
Hormonal Changes in the Body
When fasting, the body's hormones change a lot. Norepinephrine goes up, and insulin goes down. This helps the body use fat for energy.
Growth hormone also increases. This helps keep muscles strong during fasting. It makes the body composition better.
Cellular Repair Processes
Fasting starts important cell repair processes. It triggers autophagy, which cleans and fixes cells. Cells get rid of damaged parts and renew themselves.
This keeps cells healthy and helps them last longer. It's key for staying young and healthy.
Metabolic Effects
Fasting also improves how the body uses fat and sugar. It makes energy use better and insulin sensitivity higher. This helps control blood sugar and can prevent metabolic problems.
