Mr Martin, 42, has been unable to work for more than a decade owing to his weight and cannot move from his reinforced bed.
As well as his carers, who wash and change him in two shifts, he also receives visits from two nurses every other day who tend to his bed sores.
Yet despite the huge drain on public funds, Mr Martin, who is trying to lose weight to qualify for a gastric band, claimed people should not judge him.
He told the Daily Mail: “It’s either that or I would end up dead. Until people have lived like it, they can’t judge.
“Some people need help. Smokers get help, rock climbers get help if they get injured. Some people have bigger problems than others.
