The Most Dramatic Transformations Ever Seen

Like Laura Perez, Diana Bunch's food addiction was triggered by childhood trauma, but it didn't take over her life until years later. According to The Wrap, she "was molested by two older boys at 11 years old," and binge eating helped her cope. But her mother pressured her to diet even though Bunch spent her teenage years weighing around 115 pounds. Once she flew the nest, however, that all changed.

According to InTouch, the Seattle resident joined the Air Force, but was discharged because her size meant she couldn't perform her duties. Out of work, Bunch started getting bigger. She became confined to her one-bedroom apartment, eating herself to a dangerous size — a reported 620 pounds at one point.

"When you're morbidly obese, everyday life, just getting through it, it's miserable," she said during her first appearance on the show. "Pain is a constant visitor throughout my day, but my legs are what hurt the most." Her lymphedema was crippling, leaving her with swollen legs covered in open sores. "I don't look human," she said. "If I don't get help, I know that this apartment is where I'm going to die."

It was her niece, Megan, who convinced her to move to Texas and see Dr. Now, who removed 70 percent of her stomach. She was able to shed 265 pounds as a result, and is now living life to the fullest. Every Tuesday, Bunch updates her Facebook page with something she's thankful for.
