Autophagy is cellular self-cleaning — cells break down and recycle damaged components. Research shows it increases significantly during fasting, becoming notable around 24-48 hours in animal models. Potential benefits include improved cellular health, reduced inflammation, and protection against age-related disease. Eating suppresses autophagy via mTOR activation.
This companion covers what autophagy is, when it occurs, why it might be beneficial, caveats about human research, and practical applications. (3 min read)
