New Jersey Gov. Chris Christie tells Oprah Winfrey in a soon-to-be-aired interview that he’s “developed a bit of a shell” when it comes to people talking about his weight.

The interview between the queen of daytime talk TV and Christie will air Sunday at 9 p.m. on the Oprah Winfrey Network. A transcript of the talk was obtained by the AP.

“People comment on my weight all the time and they comment on yours,” Winfrey said. “Is it ever hurtful to you?”

Christ replied, “Not anymore. I think it hurt me a lot when I was younger. But I kinda think now I’ve developed a bit of a shell about it because it’s been talked about so much. I don’t like being overweight. I know I’d be healthier and better off if I weren’t.”

The governor went on to say he feels guilty about his size. “I would love to show these people who say that because I’m overweight that means I’m not disciplined. They think you can get to where I am by being undisciplined? Let me show them,” he said. “But more the guilt that I feel is in regard to my children that I wish that I could get better control of it just for my own health and my own future with them.”
