Why pakistani think it's cool being obsessed to food and overeating (esp if you are man)

I have always been made fun of because I don't eat to my full. Because it makes me less productive and drowsy. but since childhood I have been told kay mard itna thori khaatay. everyone. my parents, my sibling, my friends. Everyone makes fun of it.

There was this dua that Prophet PBUH used to ask to Allah that, "Ya Allah only give that much rizq to my Ummah so that their soul stays connected to their body"

but here everyone does oposite!
