Yeah, I am aware of why we use calories, and I understand it's importance, but I think the use case in this above example is kinda redundant, that's really what I was getting at.

However, I still don't think it's a great metric when thinking about nutrition, too reductive, it also doesn't take into account the variety of other vitamins, minerals and chemicals consumed from certain food groups which the body might benefit or draw harm from. Nutrition is kinda hard to draw scientific concensus on, I would go so far as saying it is something of a "sudo science", (or at least it has been in the past, things seem to be improving) especially as it seems that there are certain food groups which benefit certain portions of humanity better than others. 🤷🏻‍♂️

"Don't consistently eat more calories than you burn in a day" is a big part of the story, but it's not the whole story.
