Well Granet has shown us before that Gems can also have muscles, she had one moment in the show where she suddenly expended her muscle mass. Their body are physical light refraction their gems can produce, so they can form whatever body they want with some restriction, fusion enhance their abilities to project that light, hence why most fusion ends up taller.

We don't know how fusion really works on human, but since super strenght is normally a trait given to gems and fusion, we can assume that it is a way to convert Greg's fat into useful assets for battle, most gems at the end are made to fight and still have some combat capability, with Pink Diamond definitely not being a weak fighter, we can assume that the fat was converted into abs to be battle ready.

Or, the designer really wanted to see a tall buff 4 armed Greg.

Who wouldn't ?
