Okay I made a mistake. This one is on me I can admit it. I wrote per million people instead of death rate %. It makes sense that a country which has a lot more infections per million also has a lot more deaths per million.
(It is actually what I googled for, but failed to put into words as a non native speaker. My bad for the confusion)
Here is what I was trying to say :
It is pretty clear that those case fatality rates are pretty close even though the US has a 8-10x Obesity rate compared to Japan/South Korea.
So the same amount of people (from the pool of infected) die and blaming obesity on people dying of Covid seems like a big reach.
