SUPERB — Fasting vs. Eating Less: What’s the Difference? (Science of Fasting)

All the trouble in the fasting occurs during the first two or three days; that is the time of greatest hunger pangs. Go beyond 3 days. Know when to end by noting the return of hunger, possibly up to weeks later.

Ghrelin is the hunger hormone. Ghrelin comes in waves, does not linearly raise despite starvation.
