“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.”
