What is known about aerobic exercise and appetite?

Re intensity, duration, effect on hormones, any compensatory responses, etc.

For some people it increases appetite, for some it decreases it, for others it has no noticeable effect.

There isn't a one way correlation between exercise and appetite.

thanks for replying, armandouc.

i know it's far from settled, but have read that, eg, women may be more prone to an increase in appetite than men; that after high intensity exercise, appetite may be suppressed (in young fit men), but only temporarily; that formerly obese people respond to food cues (dopamine sys) after exercising, but that always-lean people don't.

For me, glycogen depletion seems to play a significant role in my hunger. It is kind of a complicated subject though. Glycogen doesn't get re-formed as fast as you digest your food, and I'm hungry until it is mostly filled back up. I have to play a waiting game, while that happens (up to two days, ugh).

Luckily, I am a pretty good fat burner. I can get up to about 600 cal/hr without depleting my glycogen, or getting hungry afterward. Yes, there is some utility to that "fat burning zone" that everyone says is a myth (but the machines show the zone/level wrong, if you are athletic at all).
