Paul Mason, who once tipped the scales at 70 stone, has been left with folds of loose skin after shedding an incredible 46 stone following a gastric bypass operation. A man once dubbed the world's fattest has released naked pictures of himself in a desperate plea to have his excess skin removed. Paul Mason, who once tipped the scales at 70 stone, shed an incredible 46 stone after undergoing a gastric bypass operation. But his drastic weight loss has left him with an estimated six stone of unsightly saggy skin hanging from every part of his body. The year-old claims that the loose skin is hindering his mobility and is affecting his health as the sheer weight of the excess folds even causes the skin to split, causing ugly, painful sores. But the NHS have insisted that his weight must be stable for at least two years before he can go under the knife again.
