World's Fattest Man Faces Fatal Reality

It is the world's fattest man!  Weighing in at 800 pounds, he has to be hoisted into the air just to change his bed sheets.

After a lifetime of food addiction, 48-year-old Paul Mason is a prisoner in his own body.  At the height of his addiction, Mason consumed up to 20,000 calories a day. That is more than eight times what the average man consumes!

He relies on a team of caretakers to prepare his meals and even bathe him.  

Believe it or not, Mason was not obese as a child growing up in England.

He recently had gastric bypass surgery.  Doctors warn if he does not lose 500 pounds, he will have less than two years to live.   

Mason was recently featured on a TLC special, World's Fattest Man.
