Personally, I get very hungry. I've heard though that exercise often leads to a decreased, rather than an increased appetite. It'll be interesting to find out what others' experiences have been :biggrin:
Apparently, cold water results in an increased appetite. Just thought I'd throw that little "factoid" out there. That's why swimmers tend to eat a lot afterwards.
When it comes to exercise in general though, I often find that it decreases my appetite. I can feel hungry and then after I've done a bit of exercise, I can hold off those feelings for a little bit longer.
