human female average healthy bodyfat percentage range is something like 21-35%
Commercial pigs are raised at optimal growth rates with feed rates set to avoid wasting too much energy storing it as fat instead of growth. optimal slaughter bodyfat percentage is somewhere around 15-20% though asian pig breeds are a little different and generally fatter. though if you grow them to heavy weights such as for ham they will be fatter.
So it seems unfair call them as fat as human women...
