You don't want to work out on an empty stomach, but also not on a full stomach. It depends what kind of exercise. If it's pumping weights, then you should have a small-moderate meal about 1-2 hours beforehand, then after the workout, have a protein or mass-gainer shake, and a decent sized meal which is rich in complex carbs, protein and fatty acids. I'm not sure what the consensus is with cardio exercises.
