Jon Brower Minnoch

Minnoch was discharged from the hospital after 28 months on a strict diet of 1,200 kcal (5,000 kJ) per day. He weighed 476 lb (216 kg; 34 st), having lost approximately 924 lb (419 kg; 66 st), the largest human weight loss ever documented at the time. He was readmitted to the hospital just over a year later in October 1981, after his weight increased to 952 lb (432 kg; 68 st). He died 23 months later on September 10, 1983, aged 41. At the time of his death, he weighed 798 lb (362 kg; 57 st) with a Body Mass Index of 105.3.

Minnoch's weight continued to increase steadily until his hospitalization in March 1978 at age 36 due to heart and respiratory failure. That same year, he broke a record for the greatest difference in weight between a married couple when he married his 110-lb (50 kg) wife Jeannette and later fathered two children. Minnoch was diagnosed with massive generalized edema, a condition in which the body accumulates excess extracellular fluid. Upon his hospital admission, it was estimated by endocrinologist Robert Schwartz that he must have weighed in excess of 1,400 lbs. (635 kg) and much of his overall body mass was retained fluid. Transportation for Minnoch was extremely difficult. It took over a dozen firemen and rescue personnel and a specially modified stretcher to transport him to University of Washington Medical Center in Seattle. There, he was placed on two beds pushed together, and it took 13 people to simply roll him over for linen changes.
