The secret is out. New Jersey Governor Chris Christie is revealing he had lap band surgery to loose weight.
The procedure took place on February 16 under cloak and dagger secrecy, when Christie checked in under a fake name at New York University Medical Centers Weight Management Program.
ABC News' Dr. Richard Besser just wrote the book, Tell Me The Truth, Doctor. He told INSIDE EDITION, "For many people, diets just don't work, and for people who are severely obese, like the governor, it can be life saving."
The 40 minute surgery began at 7a.m. Christie was home the same afternoon.
Dr. Besser said, "Basically you take the stomach, and it is a ring that goes around part of the stomach. It squeezes it down, so that it is smaller. You feel fuller sooner."
Sources say Christie’s already lost 40 pounds.
The governor says he underwent the procedure for his family. Others see the political implications of the surgery.
ABC political reporter Shoshanna Walsh said, "It was always the topic of conversation. Now, this won't be an issue, and nothing will stop him if he wants to run for president."
Christie has struggled with his weight his entire adult life. For late night comics, he's been a constant target.
On the Late Show with David Letterman earlier this year, Christie joked, "Celebrity birthday today, Chris Christie turned 50. He blew out the candles on his cake, and he wished for another cake."
Donald Trump thinks Christie's main goal is to just get healthy. He told INSIDE EDITION, "Chris Christie is a great friend of mine, he is a wonderful guy, and I think he did the right thing. He is going to do really well with it."
