Robert Earl Hughes was, during his lifetime, the heaviest human being recorded in the history of the world. At the age of six, he weighed about 92 kilograms (200 lb); at ten, he weighed 171 kilograms (380 lb). His excessive weight was attributed to a malfunctioning pituitary gland. His chest was measured at 3.15 metres (10.3 ft), and he weighed an estimated 486 kilograms (1,070 lb) at his heaviest. By the time of his death, he weighed over half a ton.
