Breakfast is not an intrinsic part of our culture - I think most of us are of European descent, apologies if I am wrong.
It's been in and out at various times in our history. And what we eat then has also been variable.
I long ago found out that breakfast cereal (and the adage "breakfast is the most important meal of the day") were both invented by John Harvey Kellogg, in his tireless crusade to prevent masturbation; but had no idea that Sigmund Freud's creepy nephew was behind bacon & eggs. Our diet has been manipulated for a couple of centuries.
Anyway, this article might supply some confidence in anyone facing pressure for not eating before noon.
