There is the fundamental thing of skeletal structure and build though - people naturally are entirely different shapes, regardless of fat or excess weight, wich is what the comment is mostly referring to in my eyes. I'm built very tall and very spindly, so there are certain body shapes that I will never have (or want, but that's a different question) purely from the point of view that my body just isn't the right base shape to produce them.
