He died, of course:

A 50-STONE giant dubbed the fattest man in Britain has died after enjoying his final fish supper.

Jack Taylor, 60, tucked into the jumbo special fish treat before going to bed.

He died in the night of a heart attack and his niece found him next morning.

50 stone = ~ 700 pounds. Yoiks.

Update: Apparently they made a film about him and another guy. Coming to a Discovery channel near you!
