Oprah talks about what she's really hungry for.

In February 2007, Oprah says she put on the first few pounds. Then, as life took over and she began to feel overwhelmed, she turned to food for comfort. "I have known since my early years of working with Bob Greene that for me it is not a cosmetic issue. It is an emotional issue," she says. "When my engine runs down, my drug of choice is food. My drug of choice used to be potato chips. Now, this year, it was organic multigrain blue chips...but a bag of them. So you eat a bag of those a day, and see what happens if you're not working out."

When Oprah gains weight, she says it means her life is out of balance. "It's not about the food. It's about using food—abusing food," she says. "Too much work. Not enough play. Not enough time to come down. Not enough time to really relax."

Over time, she discovered what she was really hungry for. "I am hungry for balance," she says. "I'm hungry to do something other than work."
