Several years ago, Renee Williams was left bedridden after a car accident and over the years, her weight ballooned to over 800-lb.
In February 2007, the Texas woman and mother of two underwent a gastric bypass surgery, but died 12 days later of from a heart attack. Before her death, Renee let the cameras into her home to raise awareness of the dangers of obesity.
Here's her tragic story:
Renee's daughter Mirina, 13, said: "I don't know why my mum ate. They told me this has been going on since she was a child. She used to hide food in her closet.
"She ate everything. There was nothing that she didn't like. Her eating habits were getting worse and worse. She wouldn't stop until her stomach started hurting.
"She'd go to McDonalds and get eight burgers from the dollar menu and eat all those."
