Autophagy Context Guide
Get a rough sense of where you might be in the autophagy process based on your fasting duration.
Important: Autophagy cannot be directly measured in humans. This guide provides general context based on current research, not a diagnosis or guarantee.
How this works
Autophagy (cellular cleanup) is believed to increase during extended fasting as the body shifts from using glucose to using stored fat and ketones. Research suggests this process may begin somewhere between 12-24 hours of fasting, but the exact timing varies significantly between individuals.
Factors that may influence autophagy include fasting duration, exercise (especially resistance training), protein intake, and individual metabolism.
