Born on September 29, 1941, in Seattle, Washington, he lived a life marked by extreme medical challenges. Minnoch struggled with obesity from his earliest years. He was an only child born to John Minnoch and June Brower. His father worked as a machinist before passing away from a heart attack in 1962. Minnoch's mother was a registered nurse and a telephone operator. Despite his physical condition, Minnoch attempted to live a conventional life. He attended Bothell High School and worked as a taxi driver for 17 years.

Minnoch's weight increased significantly throughout his life. At age 12, he weighed 180 pounds. By age 22, he weighed 639 pounds. He eventually reached a body fat percentage of approximately 80%. Minnoch owned and operated the Bainbridge Island Taxi Co. with his first wife, Jean McArdle. He was known by his community as a warm and funny family man. However, his health began to decline severely in the late 1970s. In March 1978, Minnoch weighed 12 times more than his wife. This created a record for the greatest weight disparity between a married couple.

In an attempt to improve his health, Minnoch began a very strict diet. Under a doctor's orders, he consumed only 600 calories of vegetables per day. He also took large doses of a diuretic, which is a medicine used to help the body remove excess fluid. This attempt to lose weight left him bedridden and extremely weak for three weeks. Eventually, he agreed to seek hospital care in March 1978. His condition was critical, as he was suffering from both heart and respiratory failure.

Because of his size, he could not be moved through standard doors. Firefighters had to remove a window from his home to reach him. They placed him on a thick piece of plywood to move him safely.

Transporting Minnoch to the University of Washington Medical Center required a massive effort. It took over a dozen firefighters and rescue personnel to move him. They used a specially modified stretcher to complete the task. Once at the hospital, the medical staff faced unique challenges. It took thirteen attendants just to roll him over in his bed. Doctors could not use a standard scale to find his exact weight. Instead, an endocrinologist named Robert Schwartz estimated his weight was approximately 1,400 pounds. Schwartz suggested Minnoch might have been at least 300 pounds heavier than that estimate.

Doctors diagnosed Minnoch with massive edema, a condition where the body accumulates excess extracellular fluid. He also showed symptoms of Pickwickian syndrome. This is a condition where insufficient breathing causes carbon dioxide levels in the bloodstream to rise. His medical state was described as critical, and he spent several days using a respirator to help him breathe. His body mass index reached a peak of 186 kg/m2. Throughout his treatment, medical professionals focused on managing his fluid levels and breathing. These complex physiological issues made his survival a notable medical case.

Minnoch remained in the hospital for two years while following a 2,000-calorie-a-day diet. During this period, he achieved a massive weight loss of over 500 pounds. At the time, this was the largest documented human weight loss in history. He hoped this change would allow him to start a new life. However, after being discharged, he began to regain much of the weight. He was readmitted to the hospital in October 1981 after gaining 210 pounds in only seven days. His struggle to maintain his weight loss highlighted the difficulty of managing his condition.

Jon Minnoch died on September 4, 1983, at the age of 41. His death certificate listed cardiac arrest as the immediate cause. Respiratory failure and restrictive lung disease were also listed as contributing factors.

He was buried at Mount Pleasant Cemetery in Seattle. His casket was constructed from thick plywood and lined with cloth. Because of its size, the casket required two burial spots. It took approximately 11 men to transport the casket to his final resting place. His tombstone serves as a memorial to his life as a husband, father, and friend.
