If you want to know the record holder for the heaviest man in the world, then you're in the right place. Jon Minnoch was the heaviest man ever recorded in history. At his peak weight, he was approximately 1400 lb (634 kg, 100 stone). This figure was only a close estimation, however, because his extreme size, poor health, and lack of mobility prevented use of a scale.
Manuel "Xavier" Uribe, a man living in Mexico, reached a world record peak weight of around 597 kg (1,320 lb). Uribe lost approximately 400 lbs and continued losing more weight. In March 2007, Uribe set a goal to lower his weight to 120 kg (260 lb), he has also been featured on The World's Heaviest Man

Roselie Bradford measured 1053 lbs (477 kg), but estimates that she weighed more than 1200 lbs (544 kg) at her peak two years earlier, a claim accepted by Guinness. Already over 300 lbs when she dropped out of college, Bradford became an exercise instructor, running seven miles three times a week, but continued her steady gain in weight. At her peak, she measured eight feet wide, and took up two reinforced king-size beds. After being treated for symptoms of heart failure, she was eventually persuaded by Richard Simmons to embark on a five year diet, an experience she described as hellish. Tortured by hunger, by fast-food commercials, and by dreams in which she ate without limit, she nevertheless got down to under 300 pounds, setting a world's record for weight loss. She later sued the Star tabloid for suggesting that she couldn't have intimate relations with her husband at over half a ton.
