ELI5: Why human beings eat three meals a day?

Is it some kind of standard? Tradition? Was this decided by doctors or companies? Is this due to natural processes?

It isn’t any kind of official standard. And no like doctor or anything like that came up with it or recommended it.

And the three meals a day rule isn’t actually followed everywhere, there are many places that eat more than 3 “meals”, but they’re typically smaller, so it’s like spread the food you consume out across the day.

But, around 3 is pretty typical.

And for why that is you have to ask why we eat. Because we get hungry. People tend to eat when why’re hungry.

And when are people hungry, well, when they first wake up their stomach is empty from not eating anything all night. (Breakfast)

Then a few hours later their stomach is getting empty again, so they want to eat again (lunch)

And then again towards the end of the day they’re getting chi fry again, (dinner).

It’s just really based off of when people want to eat due to how their natural human digestive system works.
