Bob Greene and Oprah

12 of 15
Bob says that when someone overeats, they are hungry—but what they really crave isn't necessarily food.

"We all seek pleasure," he says. "How do you get that pleasure or happiness or joy? And when it's not readily available in the real areas that you want—relationships, family, fulfilling career—food is a hundred times more attractive and it's readily available. It's there, and it is the drug of choice for most people."
