Appy, do you have something to eat BEFORE you exercise? A small snack such as a low/non-fat yoghurt or a complex, easy to digest carbs, such as a banana half-an hour or so before you do your thang should get your blood sugar up sufficiently and also give you sufficient energy to function properly. Exercising on an empty stomach is not particularly great for you. Also, half an hour after vigorous exercise, another small protein snack (I've been going for Greek yogurt - easy to digest, and good stuff.)
Not sure where you got the idea that exercise should decrease your appetite (unless you eat when you're bored - taking time out to get moving should take care of that). Try to eat smaller meals, more often and watch the calories. Go after foods with a lower glycemic index, if you can.
Exercise makes you hungry. A trainer once told me that the trick is not to eat anything for XX amount of time (don't remember anymore how much time it was, sorry, not much help), as your body keeps 'burning' calories for that amount of time after a workout.
That's funny Xica and VB as everything I have read has said that exercise is an appetite suppressant over the long term. Maybe it depends on the kind of food you are eating immediately before a workout and the quality of the food you are eating throughout the day and the week. If you are starving, it could be because you are not eating enough protein over the course of the day.

Although "eating small meals every few hours is ideal to create a fat-burning metabolism" may be true - everyone's different and you just have to use Google to find the inconsistent reviews of this belief - it can create a problem if done mindlessly. If you don't take the time to plan out these small meals and the associated calories, you could end up grazing your way to weight gain.
