How to use
- Adjust the slider to set your fasting duration from 0 to 72 hours.
- Read the scientific metabolic description of your current fasting stage.
- Check the real-time gauges for insulin, glycogen, fat burning, and autophagy activity.
- Review safety guidelines for extended fasts, including electrolyte intake.
FAQ
- How many hours are needed to trigger peak autophagy?
- Autophagy (cellular cleanup) typically begins to peak between 24 and 48 hours of fasting as insulin levels drop to baseline and liver glycogen is depleted.
