A week after revealing that he underwent weight-loss surgery for health reasons, New Jersey Governor Chris Christie admitted one of the main reasons he agreed to the serious procedure was his growing frustration in finding clothes to fit his 300-pound figure.

In a public appearance Tuesday, Christie said his inability to lose weight by less drastic means made him feel “frustrated and angry,” especially when it came to his daily attire, reported NorthJersey.com.

“I’d be changing out of my professional clothes and would go to casual clothes that I didn’t wear a lot and then something wouldn’t fit. That’s when I’d really be angry with myself,” said Christie, 50, admitting his self-confidence took a dive every time he would take his wife, Mary Pat, out on the weekends. “I would say to myself, ‘Why can’t I beat this? Why can’t I do better?’” he said. “It’s not as simple as, ‘Push yourself away from the table and you’ll be fine.'”

Christie announced last week that he had lap-band surgery in February, addressing the inevitable speculation that he was attempting to get in shape for the 2016 presidential election. “For me, this is about turning 50 and looking at my children and wanting to be there for them,” the governor said. But he admitted that he has yet to see any “great metamorphosis” since his procedure in February.

Christie made the admission at an appearance at a Barnes & Noble store in Princeton, N.J., alongside “Morning Joe" co-hosts Joe Scarborough and Mika Brzezinski. Christie, a frequent guest on the MSNBC morning program, was in attendance to support the release of Brzezinski’s new book, “Obsessed,” which includes an interview with the governor.
