Intermittent Fasting Metabolic Simulator
Simulate blood sugar, glycogen depletion, ketosis, and autophagy levels during a 0 to 72-hour fast
Track the biological progression of fasting over 72 hours, including insulin decline, glycogen depletion, fat burning, and cellular repair (autophagy).

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.
- Is it safe to follow the simulator's fasting timeline if I have a condition like diabetes or I'm pregnant?
- No. This simulator is an educational tool showing standard metabolic changes in a generally healthy adult. Groups such as people with diabetes (hypoglycemia risk), those who are pregnant or nursing, growing teens, and underweight individuals can face serious health risks from extended fasting. If you have a medical condition or take medication, please consult a doctor before attempting any of the fasting durations shown here.
