Earlier quoted context omitted.
Bodies are quite different, different metabolic rate, different fitness, different in many ways. I can go an entire day without eating to little ill effect. I knows people who must eat three times a day and if they miss one meal get super cranky. It’s not dismissing it to point out data vs datum or that people’s bodies vary wildly.
What I’m saying is that perhaps the “cranky” eater doesn’t even know their body’s voice. Or is angry by simply hearing it. Another way of putting it: you say you have tried but are you even sure that others have tried? People will say they have experienced but in reality have not.
I accidentally go all day without food. They must carry snacks.
