Headlines around the world about his weight have spurred the world's fattest man to go on a diet to lose some of his 368 kilos.
Keith Martin, 42, says he has not been able to leave his London home for the past 10 years, other than for four trips to the hospital.
He told Britain's Mail Online his condition has driven him to the brink of suicide and finding out he is the fattest man in the world has been the wake-up call he needed to try to reduce his 1.8 metre waistline.
"I don't blame anyone other than myself for this horrible situation," he said.
After eating up to 20,000 calories a day at one stage he has now restricted himself to 1,500 calories.
At the height of his eating, Martin would devour a packet of bacon, six sausages, six eggs with a mound of toast and beans - and that was just breakfast.
Now he has reduced his diet to just four slices of bread, sometimes topped with spam or a can of mini-hotdogs, and one ready meal a day.
Martin said he started cutting back in September when he became bed-bound by two giant hernias which are the size of four bowling balls.
Then in January, he was visited by a team of healthcare professionals in his home who warned him: "Take our advice or die."
Martin said: "I am trying to heed their advice, but nothing has hit home like the headlines around the world talking about my weight. It has been horrible, but it's made me even more determined."
He said the doctors have told him he will not reach 50 unless he does something drastic.
"I need to lose half my weight before they'll give me a gastric band."
Now stuck in his reinforced bed, each day he is visited by seven carers who hand wash him and change his sheets.
Doctors and nurses make home visits to check on his health.
The last time he left his house - other than four trips to the hospital - was on September 11, 2001, the day terror planes brought down America's World Trade Center.
