From skwigg's journal:
I workout about an hour a day. I enjoy my workouts. I don't resent them, and I always have enough energy to do them. But, I have noticed that they make me more hungry and make hunger a bit more urgent. I don't want to stop the workouts beacuse they have done a world of good for my sleep, my mood, and my stress management. I do wonder though if they're keeping me at a higher weight than I'd like to be just because they jack up my food intake a bit.
It's not that exercise makes us hungry and then we eat too much. It's that exercise makes us hungry, we ignore or deny it, eat what seems "reasonable," and then find ourselves gasping for food when it's available. It wasn't the exercise that did it though, it was the denial of adequate food. It's also cumulative. If you're very active and undershoot your needs once in awhile, no big deal. If you do it most of the time, appetite really builds. You find yourself more than making up whatever deficit you intended to create. The solution is to stop forcing a deficit, ignoring hunger, or sticking to a calorie cap, and actually start listening to your body, eating foods you enjoy to satisfaction. A predictable, adequate, and varied food intake over time ends the cycle of restriction and overindulgence.
So, it's great to be very active if you're recovering properly and eating enough. Otherwise, it gets tricky. Nobody is good at mindfulness while eating, stopping at satisfied, or being indifferent about cookies when there's urgent gnawing hunger involved.
You might find it interesting to revisit the intuitive eating hunger and fullness scale. As much as I railed against it when I was treating it as an obsessive diet rule, revisiting it this last time with curiosity and openness, I found it phenomenally helpful. With some practice, I could feel the subtleties of early hunger and feel fullness building in the moment, which I had written off as not possible. I don't put numbers to food anymore, but learning to identify all those levels between ravenous and stuffed allowed me to live happily in the middle of the range most of the time instead of ping ponging between extremes.
