ORANGE, Mass. - A British man who was once one of the heaviest men in the world is looking forward to his new life after surgery to remake his body.
At his heaviest, 54-year-old Paul Mason weighed nearly 1,000 pounds.
"It was so bad, that the thought of one day, me walking into the kitchen full of food just horrified me, scared me. It's like an alcoholic walking into a bar," says Mason told CBS Boston reporter Julie Loncich.
Mason lost nearly 650 pounds after gastric bypass surgery in England in 2010. Soon after, he realized his health concerns were far from over.
"I'd done all that hard work of getting the weight down and you're still trapped in a baggy old skin," says Mason.
Mason was left with 100 pounds of excess skin, which makes it impossible for him to exercise or even walk more than a few steps at a time.
"It's like if you had two children attached to your body -- one around your leg, the other around your middle," says Mason.
Mason is in constant pain and relies on crutches and a wheelchair. He moved to Orange in October 2014 to live with his fiancée, Rebecca Mountain, and to be closer to the New York City plastic surgeon who offered to perform skin removal surgery free of charge.
Dr. Jennifer Capla from Lenox Hill Hospital was scheduled to perform the life-changing, eight-hour-long surgery on Tuesday.
"The 980 pound person who was lying in that bed 24/7, that was a different person. After Tuesday, that will be another different person," says Mason.
Mountain, 41, will be at his bedside. The couple met in 2013 after Mountain saw Mason's story online and reached out.
"I just thought someone like that needs a friend or someone to really rally for them," says Mountain.
Mountain proposed on an episode of "The View" in 2014. The couple hopes to one day live a relatively normal life together.
"We're just trying to move on. We haven't gone on walks together...I think a lot of people take that for granted... There's a lot of things that we still have left to experience," says Mountain.
Mason will spend three weeks recovering from his surgery in a nearby hotel. An anonymous donor has offered to pay the bill.
Mason will have to undergo additional skin removal surgeries in the future, and fears mounting medical bills. A fundraising website has been established to help.
