Monterrey, Mexico - A Mexican man once listed as the world's heaviest human died on Monday at the age of 48.

The body of Manuel Uribe was brought to the Serorrey funeral home to be cremated aboard a flat-bed truck. His body was transported on the same special bed where he spent much of the last decade.

Funeral home director Pedro Reyes said Serorrey's cremation facility was the only one in the city of Monterrey able to handle Uribe's body. Reyes also stated the oven temperature was set about 60 percent higher than normal. Plans for the ashes weren't clear.

Uribe had slimmed down to about 867 pounds, after his peak weight of 1,230 pounds was certified in 2006 as a Guinness World Record. He had been confined to his bed in Monterrey for years, unable to walk on his own.

Uribe had been taken to the hospital on May 2nd because of an abnormal heartbeat. He had to be taken to the hospital with a crane by emergency and civil defense workers. In addition to a cardiac condition, Uribe was also believed to have suffered from liver problems. Doctors have not yet certified the cause of death.

Uribe married Claudia Solis in 2008, and the wedding was one of the few times he left his home in recent years. After years of diet, exercise and medical care, Uribe, had lost more than 550 pounds by the time of the ceremony. He had hoped to walk down the aisle, but despite his dramatic weight loss, he was transported to the ceremony on a flatbed truck and remained in his custom-made bed.

Uribe shed tears during the ceremony and embraced his then-38-year-old bride for a 'first dance' but didn't indulge in wedding cake. "He didn't break his diet," Uribe's mother said.

"I have a wife and will form a new family and live a happy life," Uribe told reporters before the ceremony for 400 guests.

He had been married prior to Solis, when he weighed 280 pounds. But as he grew more obese, he said the relationship grew increasingly difficult. "She asked me for a divorce," he said. "I was very depressed."

Uribe was a chubby kid, weighing more than 250 pounds as an adolescent. Starting in 1992, he said, his weight began ballooning further. In 2007, Uribe told ABC News: "I had an obesity problem for many years, a very significant one. I was gaining and gaining weight. I was on every diet you can imagine."

"I used to eat normal, just like all Mexicans do... beans, rice, flour tortilla, corn tortilla, french fries, hamburgers, subs, and pizzas, whatever regular people eat. I worked as a technician, repairing typewriters, electronic calculators, and computers. So I worked on a chair. It was a sedentary life," he said.

But his weight got out of hand. Since the summer of 2002, Uribe had been bedridden, relying on his mother and friends to feed and clean him.
