When I was younger, breakfast was my big meal of the day. I remember times when for one reason or another I didn't get a breakfast, and I was literally ill because of it.
Years later now, my appetite has changed. It has definitely increased with my weight training, which makes it a lot easier to get enough calories, but for some reason breakfast is no longer the big meal for me. I never feel hungry when I wake up. About 11-12 is when I start feeling like I need some food.
I'm starting to think staying up late has screwed up my body clock.... that would make sense right? any other theories?
.... oh, and I always get my breakfast down anyways, hungry or not...
