Thanks for taking the time to reply!
I think the use of the word catabolic was a bit stupid of me, I don't believe you're going to go catabolic, but I'm still not completely convinced the body could be in an anabolic state throughout the night if I don't eat for 12 hours (say 6pm->6am or 8pm -> 8am).
I might look into that Barry Sears thing, sounds interesting
