There is a lot that I don’t know on this subject for sure and something I’d like to find out is linked to your comment – “Is it just as good to eat right before a workout (45-60 mins in length) as it is to eat immediately after?” If the body is still digesting when you’re done the workout, then I’d think the answer is yes. That said, I don’t know. I think the key is to make sure your body has fuel and protein to take in post workout as that’s when the body is most apt to absorb it.
