World's fattest man dies from pneumonia at 44

London: A British man who held the title of world's fattest man after once weighing 70 stone, has died aged 44.

Morbidly obese Keith Martin, who had been bed-ridden for years, died from pneumonia just eight months after having a gastric sleeve op that removed three-quarters of his stomach, the Daily Star reported.

Keith, who was depressed and unemployed, used to eat a monster fried breakfast, followed by a steady stream of pizzas, kebabs, Chinese takeaways and Big Macs for lunch and dinner.

Keith had a room mainly for the huge piles of cheap fast food, like, sandwiches, chocolate, crisps, sweets and biscuits, six points of coffee and two litres of fizzy drink.

Surgeon Kesava Mannur, who operated on Keith at Homerton Hospital in east London in 2013, said that the government needs to make unhealthy fast food more expensive, or else, more and more people like Keith will be seen.

Mannur, who has treated several people who weighed between 45-60 stone in the past few years, added that in Keith's case, it's a shame because he'd had successful surgery despite being high-risk because of his size and it was unlucky he then caught pneumonia.
