To be honest, I don't really notice a change in my appetite from exercise. In fact, I feel calm, peaceful and content for the hour following a workout -- but not hungrier.

Based on my current volume of LC food, I eat at a 1000 calorie per day deficit (give or take a few), I eat until I'm satisfied and generally don't feel hungry between meals. A good walk or weight training makes the deficit even greater -- as I tend to eat the same volume of food everyday.

This may be more true for those in carb burning mode. I'm a fat burner - and if I do feel more hungry after a workout, then my brain didn't get the memo. I'm still far from my goal weight. Perhaps this will change when I don't have that much fat left on me to burn.
