Honestly I think a lot of us are so sensitive to issues about our weight that we over personalize some of these questions. And I personally think that as a society we've gotten really weird about personal questions anyway. People think it's ok to ask all kinds of personal questions in depth about finances, diet, jobs, sex life, whatever. And people over-share all the time. But then someone asks *them* a question that they feel is invasive or touches a nerve and they get upset. (Not saying this is what the OP did, just that it's a trend I've noticed in general.)
It's hard to know where to stop and start any more or to judge what will offend one person and not another.
In this case it sounds to me like a question someone would ask either as conversation. Or, it could be genuine concern if this is someone who doesn't know you very well - are you allergic? Or is there something about pizza that *I* don't know that I should be avoiding for too? Or anything like that.

I like Tomato's response the best because it doesn't attack the person for just asking a question and possibly just trying to be friendly or concerned.
