Fair argument, but I don’t think criticizing their weight benefits either party. Unless you’re a super close friend and you do it occasionally as a reminder when they are going off the rails.

My family constantly says I’m on the bigger side - but does it help? Absolutely not. Does it hurt? A little bit, at least. Then they shame you for “going on a diet”, but also asks why you don’t eat. I don’t need others to pile their opinions on top of it.
