Quick guideline that'll help you be more empathetic to the rest of humanity: other people's experiences aren't like yours. Their bodies behave differently, they have different socioeconomic statuses, their minds struggle with things yours finds easy and vice versa. So "skip a meal" is trivial for you and impossible for another. That's why many different diets exist.

Stop painting humanity with one brush just because you can't see outside your own world view.

Also: A chunk of human history where we skipped meals regularly also involved getting eaten by predators. Just because it was true in the past does not make it true now. Having access to calorie bombs 24/7 is normal now. And society hasn't figured out how to deal with that. Some handle it fine, others handle it poorly.

I eat two meals a day. I drink mostly plain water, with some black coffee and unsweetened tea. I cut out soda over a decade ago and sweets are a rare luxury. I can't afford to eat massive amounts of food even if I want to. So why am I still fat?
