Fitness hog in my mouth

This is true, but sorta misleading/meaningless.  The study on that is going by the BMI defintion of obesity.  IIRC, something like 73% of Americans are overweight or obese.  And 78% of Covid hospitalizations are overweight or obese by the same definition.

I would imagine there's a correlation as you get even fatter, but the way this news was portrayed it was kinda like, "Hey fatties, stop being so fat and you won't get sick."  But "fat" by BMI is an absurd number that's largely meaningless IMHO, and that 78% isn't way out of line with the total population so I'm not sure there's really much of a takeaway here.
