3 meals a day + snacks don't make sense for the body but good for business.
— Advertising slogan, Kellogg’s 1917
If I do eat early my body takes hours to get to full energy again. It literally makes me tired.
My girlfriend doesn't work that way. And I have no idea why this works so well for me.
It's certainly not the most important meal of the day in general. Especially as a societal meme that came directly from an advertising campaign for a cereal manufacturer.
