A recluse believed to be Britain’s most obese person has died of suspected heart failure, aged 22.

The body of Liam Johnston, who weighed 419kg (66st), was carried out on a bed frame after firefighters removed his front door to make room.

Paramedics were unable to revive Mr Johnston on Thursday.

He was believed to have a body mass index of well over 85 – anything more than 30 is obese.


Last year, he was convicted of using stolen credit cards to order four pizzas and put on a waiting list to have gastric band surgery.

Mr Johnston, of Livingston, West Lothian, said at the time: ‘I hid myself away from the outside world, ashamed at the size I had become.’
