OP, sorry, it might be my ancient computer, but if there is an image or something next to "for this reason" then I can't see it. Oh well, never mind.
I don't even see what issue is being considered tbh. If it's a long way of saying "be diplomatic when talking casually about weight" then it's a waste of time, but I suppose someone got paid for writing it.
if, as a PP said, it's suggesting that a person weighing 350lb should be considered the same, medically, as a person weighing 150lb, then that would be mad.
