That's a good question. The more I think about it the less it seems to mean. I know he doesn't mean food and whatnot. For one thing, when truly thinking about what both sentences say and mean, they don't really mean anything together. I see why you ask. He does mean the sort of "breaking code of behaviour", even though one can't really have an "excess of effort", you can have an excess of certain foods or entertainment, but the idea of an excess of a behaviour doesn't really work. That's a very linguistically strange quote.
