if you can get up early enough you should eat an apple or something, they say eating within 45 min of waking up helps kick your metabolism into gear in a good way. but, you don't want to eat anything too much. Try it on an empty stomach first and see how that makes you feel.
What about eating after you work out? Is it good to have something small like a half peanut butter sandwich or fruit, or just wait a while to eat?
