Autophagy Clean-Up

Fasting is not only about burning stored fat. When food gets scarce, your body also starts a kind of recycling process called autophagy. It finds damaged, worn-out parts of cells and breaks them down into materials it can reuse.

The exact timeline is still debated, but it is reasonably understood to ramp up during longer windows without food. My first long fast started from a simple thought: if my body has a built-in clean-up system, why not give it the chance to run?

This is not a miracle cure or a way to reverse aging. It is plain maintenance. When food is always available, your cells stay busy processing it and storing the excess. A real break from eating gives your body the chance to clear out the debris and reuse what is worn out. You cannot feel it happening, but knowing that it is gives the long hours of a fast a point. Those empty hours are not just you going without. They are your body getting room to tidy itself up.
