Governor Chris Christie took a break from his Obamacare bashing to talk about a more personal issue on Tuesday night's Nightline: his weight.

Christie is well aware of the problem and its been an issue for him over the past 30 years. He says he is “trying to eat better,” but told ABC News' Jake Tapper on Nightline it's  "difficult" given his job and all the "running around all the time and grabbing things on the go."

“I mean, see, listen, I think there’s a fundamental misunderstanding among people regarding weight and regarding all those things that go into, to people being overweight,” Christie tells Tapper. "I  think folks say — yeah, well he must just not be disciplined, you know, or he must not have willpower — that kind of thing. I guess the best analogy to make is some people drink too much. Some people take drugs. Some people eat too much. See, you can go live every day without drinking. You can live every day without taking drugs. You can’t live every without eating.”

One thing he won't try is gastric bypass surgery because he feels it is  “too risky.”

Christie didn't stay completely away from politics during the interview, taking on New York Mayor Michael Bloomberg's proposed ban on large soft drinks.

"I just think it’s government run amok. Government run amok. People have to make choices," told Tapper. "Sometimes they’re going to make good choices, sometimes they’re going to make bad choices. But I don’t think we should have a daddy state."

Tapper also asked about being Mitt Romney's running mate on the GOP ticket to which Romney replied that any conversations between he and Romney are "between me and Mitt Romney."
