Oprah: What did you used to binge on?
Kirstie: I wasn't a binger. I was just a massive eater.
Oprah: You ate volumes of food?
Kirstie: Volumes. You know, I've always worked out my whole life. I was an athlete. And when you are an athlete, that's probably the good thing. The best news about what's happening to me now is that my body is going back fairly easily…because of all my training.
