A couple theories to kick around:   A reasonably symmetrical round face isn't always bad thing for a human (baby faces can be cute) so it doesn't immediately set of any drastic alerts. In this case, the ham looks quite young, which could fool me on a first glance until I saw her arms and hands. Young hands look young (compare your or your child's hands to your parents or grandparents). Fat shoulders, arms, and hands are just fat and always belong to fat bodies.   You're still quite optimistic at the core: you still can't conceive of anyone being fat to the point of bodily deformity when they have a near human face.
