World's fattest man hospitalized

The world's fattest man was in a hospital Friday after a suspected heart attack, just one week after he announced plans to write his autobiography revealing his weight-loss tips, foreign media reported.

Paul Mason, 48, was rushed from his home in Ipswich, Suffolk Thursday night in a reinforced ambulance after suffering agonizing chest pains.

Mason - who used to be 440 kg but slimmed down to 310 kg - was seen clutching his chest and gasping for breath as paramedics hoisted him onto a massive stretcher bed.

Medics at Ipswich Hospital would not say whether his condition was stable.

Ex-post officer Mason had been back at his specially-adapted bungalow for just a week after a life-saving gastric bypass operation.

He had to slim down from his peak last year to have the surgery - but is still the world's heaviest man.
