frosted shredded wheat for me! I know the frosted part isn't that good for you but it really helps curb the stomach. And it is fiber too. But yes i tend to be famished from biking as well. I recommend some kind of protien as well. Peanut butter on sproited grain is always good. As long as it's not skippy (to much sugar) But if that is what you like go for it. top it off with some carrots. It's about what you eat to feed the monster.
