Actually, you should eat some simple carbs an hour prior to working out so your body has the fuel it needs to maximize your training. Also, you have an hour after your workout to replenish your body with the essential protein needed to promote the lean muscle growth.
Oh I see, thanks Darrin

If you don't want to lose muscle mass, you need 15-20 g protein or additional supplements before AND after or your body also uses muscle mass as fuel. The more muscle, the more fat-burning. Try to keep calories down beforehand though. If you don't have the option, it is better to do it fasted then pump in protein within 60 minutes after the workout.
