Exercise can push off hunger pangs for quite a while. Your body wants you to know it’s hungry, but if you’re exercising (read:probably hunting according to your brain), the pangs fade because they would simply be distracting.

Thanks. I've never heard it framed this way. I've mentioned my appetite diminishes after aerobic exercise, but a common response is that I'm weird.

Interestingly my appetite sometimes skyrockets after certain activities like bouldering or weight lifting, so the diminished hunger response must be a bit more complex of a phenomenon.
