"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 said in an interview on "Nightline." "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."
Besides his weight, Christie said last year that he was healthy.
"My blood pressure's fine, my cholesterol is fine," Christie said. "I'm in good physical shape in terms of those indicators. But I have to lose weight and I get it."
Christie said there are two types of people who approach him about his weight: those who "really genuinely are concerned about me and want me to be around for a long time, and really care about me" and some of the people he sometimes encounters on his Twitter feed.
"There are some people who are just — you know, incredibly nasty and, and ugly and horrible," Christie said. "That's just the way it goes. I mean, you know, people have that kind of prejudice about them. I can't do anything about that."
