Juan Pedro, 32, who is considered the world's heaviest man at 1,100 pounds, has left his bed for the first time in six years.
"I think there is a new hope, a door that's been opened for me," Pedro said, in a Spanish interview with the Associated Press. "And here we go, to see what we can do about this."

Pedro, from Aguascalientes in central Mexico, was assisted out of bed by medical personnel earlier this week to seek treatment for his obesity, and the plethora of related health concerns.
He was transported to the nearby town of Guadalajara, located approximately three hours away, where he was medically evaluated.
According to The Telegraph, Pedro said, "I never knew what was happening to me."
As a result of his unmanageable weight gain, he has been diagnosed with type 2 diabetes, thyroid problems, liquid in his lungs, and hypertension — all of which could likely kill him.
"He is probably only still alive due to his youth," said Dr. Jose Castaneda, the director of Gastric Bypass Mexico hospital in Guadalajara.
Pedro said he was born at 7.5 pounds, but gained more than 20 pounds a year during his childhood.
The problem went undiagnosed, since Pedro's family did not have the resources to help him get medical attention, or even the right kinds of food and medicine.
But despite those setbacks, "he was a good cumbia dancer, and had two or three girlfriends," his mother Maria de Jesus Salas told a local newspaper.
His weight skyrocketed following a car accident that left Pedro virtually immobile when he was 17 years old.
"My body just followed its own path without any control whatsoever. I tried to diet day after day, but nothing worked and I became desperate," Pedro told The Telegraph.
In the last six years, he has been unable to get out of bed due to his weight, but his mom said she hopes that his mood will improve if he can leave the home, where the family runs a small shop.
"When he still went outside, life was different, it was better," she said. "But in one of the depressions he had, he didn't want to go outside anymore. And when he wanted to, he couldn't move anymore."
According to officials, he will remain in Guadalajara for several more months as he receives treatment.
