I didn't get the idea that he was saying that 1200kcal was an everyday thing; if it was, then I totally agree. I can picture having 1200kcal days here and there when he's not really active though, like his aforementioned 12-15 hour hacking days. The main point being: listen to your body. I you feel like you really need to eat something, then eat something. If you don't, then don't.
