So many comments here claiming to understand the effect of fasting on humans generally through personal experience. Come on, people - your experience is a datum, it's not data, and your entirely subjective conclusions drawn from that datum are not analysis. People's response to fasting varies widely. Hunger is both a physiological and a psychological phenomenon - and like any phenomenon with a psychological component…
We want to understand the way things work, and correlation can give us hints. But so can individual experience. But "data" is often used as the truth.
So yeah individual experience here is valid. Hunger is not as simple as every hour you eat you get more hungry, and that's valid to deduct from personal experience.
