I'm sure I'm not the only one to send a link to the children's book "Porko von Popbutton", but I remember it vividly from childhood (it was actually published in Sports Illustrated back in the '60s, which I did not know). The hero is a bullied fat boy who gets sent to a hockey-mad boarding school.
I don't know about hockey, but obese athletes already changed Olympic bobsled.
