Diet is huge. Eliminating inflammatory foods like sugar, refined carbs, and foods that you may be sensitive to can have a very large impact on your recovery. In my opinion, you can't go wrong by eating 'mostly' real foods... types that aren't packaged or processed. Following an 80/20 protocol is a smart move that allows flexibility.
