Even after more than 30 years have passed, Jon Brower Minnoch is still the world's heaviest person on record, weighing in at 1,400 pounds.
The Guinness Book of World Records lists Minnoch as the heaviest man in medical history in its 2012 edition.
Minnoch, who had been morbidly obese throughout his childhood, was born in 1941 in Bainbridge Island, Wash. As the heaviest human being ever recorded, he died in 1983, shortly before his 42nd birthday.
At age 12, Minnoch weight 290 pounds before increasing to 392 pounds by the time he was 22, standing at six-foot-one. Just three years later, at 25-years-old, Minnoch nearly doubled his weight to 700 pounds. In September 1976, he weighed almost a half a ton: 975 pounds.
According to Guinness, 37-year-old Minnoch was hospitalized in Seattle at University Hospital in 1978 for cardiac and respiratory failure, where endocrinologist Dr. Robert Schwartz estimated (since he could not use a scale) that Minnoch weighed 1,400 pounds, his peak, record-breaking weight. Dr. Schwartz attributed the weight to water accumulation stemming from congestive heart failure and edema.
Guinness World Records archives said after the hospitalization and a strict diet of no more than 1,200 calories per day, the former taxi driver weighed 475 pounds in July 1979. However, before he died in 1983, Minnoch put on more weight, weighing in at 796 pounds.
Jon Brower Minnoch reportedly married a woman named Jeannette, who only weight 110 pounds, which he had two children with.
Mexican citizen Manuel Uribe is the second heaviest person in the world, and heaviest currently living man, at 1,320 pounds. Uribe reportedly lost over 500 pounds from 2006 to 2008.
