Cereal: wow, that's a ton of food. Way more food than I eat, more water too.
I find that I actually eat far less when I'm getting regular exercise than when I'm not. I have no explanation for this other than I assume my digestive system gets more efficient. Also I think that since I tend to not eat for a while in the morning, my body switches to fat burning, and I do currently carry probably a good 20 pounds of fat that I could stand to lose. Perhaps if I ever do lose it I'll have to switch to eating more again.
