In my mind, diet is comprised of food choice and food timing. For food choice, I've stuck with the "Perfect Health Diet" guidelines for a few years now. It's basically Paleo, but with more starchy carbs and healthy fats. For food timing, I usually don't eat until mid day or a little later (I will have some almonds or something to take the edge off some mornings, but there usually isn't an edge to take off), then again a few hours before bed. I can train at any point in the day without adjusting how/when I eat. Although I don't train S&S currently, I train in a similar manner and I have eaten this way while doing strict S&S. That being said, when I was new to fasting, I couldn't train at all while I was in a fasted state without feeling terrible afterwards.
