There's almost no work-related thing I dislike more than a meeting that's scheduled anywhere between 11:30 and 1. Oh I'll go, but unless you're going to feed me, I won't be gracious about it.
I come in early and stay late every day for the opportunity to leave my desk for an hour starting around 11:30, get a change of scenery and eat something that hasn't been squished into a bag in the refrigerator all morning.
I know that the people who set up meetings cannot help but be tempted by that blank space in the middle of my calendar, but they should really resist. I'm not nearly as nice with low blood sugar.
