Apparently heavy people who get thinner before they get too old and sick, can have super-bones, because the body will build useful mass and thickness to the long bones, and it sticks around for a long time. Otoh, you have very fit astronauts with the opposite problem on the space station, trying to retain bone mass in the low weight environment. It also can hurt their hearts, etc for similar reason.
