It’s kinda tough to get a good baseline of what people are talking about without real numbers - like I’d personally rate my carb consumption as “moderate” - I don’t eat meat so it’s tricky to meet my Calorie needs by cutting out rice and increasing my bean consumption. OTOH the added sugars in my diet are practically zero.

I wonder if that is really true globally. You can't really escape carbs in some cuisines like Asia and some of them are really doing just fine.

What you're saying makes no sense without context. You say "we" but someone who's extremely active vs extremely sedentary are going to require different macros to compensate.
