Autophagy is your cells' self-cleaning process, but it needs about 72 hours of fasting to actually activate. Daily intermittent fasting probably won't get you there. Research on longer fasting-mimicking diets shows real increases in autophagy and stem-cell regeneration.

Autophagy is the cell's internal self‑cleaning system that identifies and removes damaged or non‑functional components. To truly trigger autophagy, a fast of at least three days (around 72 hours) is typically required. Consequently, everyday intermittent fasting does not provide enough duration to achieve deep cellular cleanup, whereas fasting‑mimicking protocols like ProLon, which emulate longer fasts, are linked to increased autophagy and stem‑cell regeneration.
