Yeah, it should be considered just as wrong. Still, unless I get told that I should gain weight in a rude manner, I genuinely don't feel offended. We don't really use "go eat a sandwich" in SpanishAlso I don't know who decided it was ok to tell people they're too thin. I get that quite a bit and I think, if it was reversed and I told somebody they weren't thin enough I'd get demonised so quickly.
