The stage timings come from a rule-of-thumb model informed by published research and real-world testing, and they are an approximation: what stage you are actually in depends on your metabolism, your last meal, your activity and much else. Talk to a doctor before fasting, especially if you are pregnant, are taking medication, or have a medical condition.
