PHOENIX -- At 700 pounds, Colleen Williams knows she has to do something to change her life, but she also knows she cannot do it alone. That's why she wrote to Dr. Oz for help.
Dr. Oz was in town a few weeks ago to meet with Williams, 31, who is being featured on his show Wednesday night and Thursday morning.
Williams, who lives in Phoenix, is an intelligent woman and says that her weight is not an issue of willpower or lack thereof. She says for her, food is an addiction and compulsion.
"It's a comfort for me," she explained. "I don't really have any other coping skills, I think, other than turning to the food. That's all I've ever known."
Williams said she binges, and often eats in private.
"When Dr. Oz was here, and he said 'We're trying to figure out why rational people do irrational things,' I do think that that's the key," she said. "I am a smart person. I am a capable person. In every other facet of my life, I feel like I've been fairly successful.
"In this particular area, it's just been something I haven't been able to beat. I'm frustrated that I can't think my way out of it. I feel like I can think my way out of anything, and the fact that I can't is so frustrating."
Williams has lost weight before, only to gain it all back -- plus more. She hopes this time will be different.
"I'm in so much pain, all the time," she said. "With the tools that I'm being given at this point, I really think we're really going to turn a corner."
One of the things Williams had to do was have blood drawn, which was difficult because she has a severe needle phobia. It's so bad that she had not had blood work in 15 years.
"Dr. Oz was great," she said. "He got me through it."
The results, however, were difficult to hear, although there was some good news. While there are issues she will need to deal with, Williams, who says she's been overweight all her life, is not diabetic. She was overjoyed to find that out.
Williams' goals are fairly simple.
"I want to have a better life," she said. "I want to live a better life and I want people to see that not everyone who is overweight is sloppy or lazy or unintelligent or incapable.
