Christie appeared with MSNBC morning hosts Mika Brzezinski and Joe Scarborough at a Barnes & Noble Tuesday, to help promote Brzezinski's book, which includes an interview with Christie about his weight, The (Hackensack) Record reported Wednesday.
"The things that really got me down, the moments where I would say to myself, 'Why can't I beat this? Why can't I do better?' It would be when I'd be going out with Mary Pat on a Friday night or Saturday night," Christie said, referring to his wife in response to a question from Scarborough.
Christie disclosed last week he underwent gastric band surgery, a medical procedure to help him lose weight, in February.
