I think the best approach may be to try different meal strategies. There is no one right approach. What works great for me may be a disaster for you.
I would recommend commiting to one food plan or strategy for the week. It could be high protein, high carbs or nothing but candy and cigarettes
. Decide what you are going to eat, plan how to make it happen and then stick to it. Through the week keep a log of how you feel before, during and after your work out. Throughout the week keep the food style and volume the same but change up when and how much you eat. The next week try a different food strategy.
After a few weeks of this you can start to see trends. Maybe your body responds to a big breakfast or only a small snack before a workout. Are your muscles more tired and sore when eating one style of food? The key is to find what your body wants.
