Which is it.. Eat 30 minutes to an hour after getting up or do you work out first and then eat?
Personally, if I'm able to get myself up to workout in the morning, I like to have something small (raisins and banana, piece of toast with pb) so that I actally have some energy to work out, and then have another small breakfast when I'm done (yogurt, etc.).
I've heard Tim Ferriss (author of the 4 hour body) say you should get 30g of protein within 30 minutes of waking up. I don't know what that is based on, but I will usually try to get 150-200 calories in my body at least 30 minutes before working out first thing in the morning. I will wake up at 5 AM and drink a 200 calorie protein shake, then go back to bed for 45 minutes, then get up at 5:45 and workout, since I think it takes around that much time for that food to be available to your body as energy.
I've also heard you can burn fat more efficiently if you have an empty stomach while you work out. The idea being that your body won't have any simple carbs in it after not eating for 8+ hours, so your body turns to fat. However I think it makes much more sense to eat before working out. If you're properly hydrated and have eaten, you'll have more energy, which will allow you to work harder and push yourself more, causing more stress to your muscles.
