Autophagy, from the Greek words for 'self' and 'eating,' is your body's cellular recycling program. During autophagy, cells break down and remove dysfunctional components, essentially cleaning house at the cellular level.
What is Autophagy?
Autophagy is a natural process where your cells degrade and recycle damaged proteins, organelles, and other cellular debris. This cleanup process is essential for cellular health, disease prevention, and longevity.
When Does Autophagy Start During Fasting?
Autophagy begins increasing after 12-16 hours of fasting and becomes more significant after 24 hours. Peak autophagy occurs around 48-72 hours, though meaningful benefits occur much earlier.
- 12-16 hours: Autophagy begins to increase
- 18-24 hours: Significant autophagy activation
- 24-48 hours: Strong autophagy response
- 48-72 hours: Peak autophagy levels
Benefits of Autophagy
- Removes damaged cellular components
- May help prevent cancer and neurodegenerative diseases
- Supports healthy aging and longevity
- Enhances immune function
- Reduces inflammation
- Improves cellular efficiency
How to Maximize Autophagy
- Extend fasting periods to 16+ hours
- Avoid snacking between meals
- Exercise during fasted states
- Reduce protein intake slightly (triggers mTOR reduction)
- Consider periodic longer fasts (24-48 hours)
- Prioritize sleep for optimal cellular repair
