What is Autophagy?

By

Quick answer

Autophagy: definition

Autophagy is the cell's recycling system — the process of breaking down and reusing damaged or unneeded cellular components.

Autophagy, explained

The word means “self-eating.” Autophagy clears damaged proteins and organelles such as worn-out mitochondria, helping cells stay healthy. Disabled autophagy is one of the recognized hallmarks of aging.

In animal research, fasting and exercise stimulate autophagy. In humans it is difficult to measure directly, so claims about exact fasting windows should be viewed cautiously.

Why it matters

Efficient cellular clean-up is linked to healthy aging. Exercise remains the most practical, well-supported lever.
