Who is the fattest person to ever live

Heaviest Man
The heaviest person in medical history was Jon Brower Minnoch (USA, 1941–83), who had suffered from obesity since childhood. He was 185 cm (6 ft 1 in) tall and weighed 178 kg (28 st) in 1963, 317 kg (50 st) in 1966 and 442 kg (69 st 9 lb) in September 1976.

In March 1978, Minnoch was admitted to University Hospital, Seattle, where consultant endocrinologist Dr. Robert Schwartz calculated that Minnoch must have weighed more than 635 kg (100 st), a great deal of which was water accumulation due to his congestive heart failure.

In order to get Minnoch to University Hospital, it took a dozen firemen and an improvized stretcher to move him from his home to a ferry-boat. When he arrived at the hospital, saturated with fluid and suffering from heart and respiratory failure, he was put in two beds lashed together. It took 13 people just to roll him over.

After nearly two years on a diet of 1,200 calories per day, he was discharged at 216 kg (34 st) – the greatest weight loss for a human being. In October 1981, though, he had to be readmitted – after putting on over 89 kg (34 st). When he died on September 10, 1983, he weighed more than 362 kg (57 st).
