Doctors delivered a stark ultimatum to a 39-year-old Englishman, who grew to a colossal 60 stone, 840 pounds. Colin Corfield's battle for survival was the subject of a poignant and moving ITV television documentary.

The Runcorn pub landlord in Cheshire was warned two years ago that his own body fat could suffocate him. So he decided to take drastic action and have risky gastric surgery. It has proved such a success that he has now shrunk to 16 stone!

In the TV program screened in December 2007 he said life was "fantastic" and he was looking forward to his first real Christmas in decades. "I won't be stuck in a corner watching everyone else, feeling like I'm putting people out. It's my first Christmas as the new me."

While Colin has a new appetite for life and can walk everywhere, work properly, socialize and feels good about myself, it wasn't always that way. As a teenager he found it hard to deal with a drinking domineering father and he turned to food for comfort. He was obese by the time he reached 30 and when he began running his own pub, his weight spiraled out of control.

"I was a big fella so I could drink 20, 30 pints in a day and not get drunk," he recalled. He ate takeaways at 2 am. He snacked on crisps, chocolates and junk food all day. He tried diets and several times managed to lose 10 stone, but then he would put it back on again.

By the autumn of 2005, Colin was so big he couldn't leave his bed and simple tasks like going to the toilet and getting washed were impossible for him. "I'd never let anyone weigh me. But I must have been 60 stone. I couldn't walk more than a few steps or go out," he remembered. Whenever I could, he would go up on the roof and hose myself down with a hosepipe "like an animal" and he would use a bucket for a toilet.

Nights were especially dangerous. Colin needed an oxygen mask so his weight wouldn't crush his lungs. "It was degrading. I was so depressed. I couldn't see the point of going on," he said, admitting he had contemplated suicide.

Then he saw a TV program about gastric surgery and thought it would work for him. His family found a surgeon willing to cut away most of his stomach and his mother sold her bungalow to raise the necessary 32,000 U.K. pounds. But despite Colin cutting down on alcohol and food, and slimming to 48 stone, the surgeons' instruments were too small to cope with his size when they tried an operation in November 2005.

"I was distraught," Colin said, told he had to lose another 10 stone. He went back to his diet and hired out a local pool to swim in private. He reached his target weight of 38 stone in November 2006 and the drastic surgery finally went ahead. The doctors had warned him that one in 19 people die during the procedure but Colin was happy to take the risk. If I hadn't he would have died anyway, he believed. Colin has now been left with a stomach the size of an egg, enough for him to survive on. Instead of a large cooked breakfast, he now begins his day with a single Weetabix. He has also replaced the pints with an occasional Southern Comfort.

"Food isn't a big deal for me anymore. I was addicted but now I am full after my small meal. Now I feel fantastic. "I was very, very sad at the time I was heavy. But I'm not sad anymore - I've got my life back. "I can go back and watch the match at Everton. I used to do it all the time before I got too big to get through the turnstile," said Colin.
