I'm the same way. People always nag me to eat breakfast but that actually just makes me hungrier and throws off my schedule. Generally if I don't eat anything I won't get hungry for a few hours after waking up, until 11-11:30 like you. I'll have a "big" lunch, like chipotle burrito size, then a light dinner 7-8 hours later. No snacking and stick to drinking water, black coffee, and alcohol. I remain at the same weight I was in high school and haven't fluctuated more than +/- 5 pounds over my entire adult life. It honestly rules and I don't even know how I got into this routine, just that eating breakfast usually seems gross to me.
