Documentary about Britain's fattest teenager, Jonathan Wallace. In this film Jonathan has a gastric bypass operation - but for it to work, he needs to change his lifestyle completely: not easy in his home town of Hartlepool, where fast food restaurants abound. With a busy mum who's not averse to paying for the occasional KFC herself, Jonathan is mostly left to his own devices. Will the weight stay off, or will the operation fail as Jonathan, left alone, gorges himself on up 8 meals a day?
