Weighing the same as five baby elephants and a shade less than a Mini Cooper, Patrick Deuel is one of the heaviest men ever - and a medical miracle. His heart and other organs should have collapsed long before he reached his record-breaking weight of 76 stone 8lbs.
Patrick has been lifted through a removed wall and taken to hospital in a reinforced ambulance, put on a diet and given a gastric bypass operation. Once home again, he must decide whether he wants to live - or to continue eating himself to death.
Rosalie Bradford, who was once one of the world's fattest women, lost an incredible 900 pounds only after she realised that her food addiction was a reponse to childhood neglect.
Bodyshock looks at both of these stories, and the growing number of people who appear to be eating themselves to death.
