From what I understand, eating patterns long ago were influenced by things like daylight and food availability. But today, most people follow the “3 meals a day” structure (let me know how many meals you eat!).

I also came across a clip that mentioned fasting might have benefits, which made me want to look into it more.

From a nutritional perspective, is there evidence that “3 meals a day” is optimal? Or is it influenced by governments and corporations? Or other factors I’m not aware of? I’m trying to understand the line between nature and industry.
