Nineteen year old Billy Robbins weighs 60 stone and is reported to be the world’s heaviest teenager. He has spent the past three years living in a chair as his mother cooks for, cleans and feeds him. But Billy has made the decision to turn his life around in the hope that one day he may be able to move out of his mother’s home.

Billy realises that after being fed up to 8,000 calories a day, he has to change his diet not only in order to gain his own independence from his mother, but if he is to live into his twenties.
