A partial transcript from the NBC interview follows:

BrIan Williams LIVE INTRO: The Republican Governor of New Jersey, Chris Christie has undergone lap-band weight reduction surgery. The story broke in this morning's New York Post.. its not known when the Governor was planning to say something himself, but there has been a noticeable reduction in his weight just in recent days.

Today we sat down for an exclusive interview with the Governor alongside the newly re-built boardwalk in Seaside Heights, New Jersey, mostly to talk about the Sandy recovery - and it turns out Sandy forced a delay in his surgery until President's weekend of this year, when he checked himself into the hospital on a Saturday morning under an assumed name.

Chris Christie: Last fall I was turning 50 and it really was a moment of reflection for me. And so I really just Felt like for Mary Pat and for the kids that I needed to take a more- a more significant step to try to get my weight under control so that I could have a really active next half of my life.

BrIan Williams ON TAPE: The Governor sought the advice of Dr. George Fielding at the NYU school of medicine in New York, a pioneer in the field of weight-loss surgery.

Chris Christie: I said, "Well, do I really think I need this?" And he said to me, "If you came in here with cancer and I told you that I had a 40-minute surgery that'd give you a 90% chance of cure- would you sign up?" And it just really crystallized it for me. And I said, "Yeah, I would." And he said, "Well, then why wouldn't you do that to cure obesity?"

BrIan Williams ON TAPE: The Governor said he also consulted Rex Ryan - the New York Jets head coach who had successful lap-band surgery himself.

BrIan Williams: Rex Ryan has a great phrase that a lot of people who've been through the surgery use, "Listen to the band." And that's what's going to- you're just starting out, but that's what's going to guide you?

Chris Christie: Oh listen, there's no question. And sometimes, whether you want to listen to the band or not, it forces you to listen. And- but the biggest thing about it for me has been I'm just not very hungry anymore, and that's a huge change for me.

BrIan Williams: And this is tough here 'cause this is our turf.

Chris Christie: Well, yeah, you know, the sausage and peppers have always been a problem.

BrIan Williams: Yeah, oh boy.

Chris Christie: But you know, I don't feel, like, every day like I have a significant amount of hunger. And that really helps.
