Maybe I'm taking this song too literally, but I just think it's about finding yourself without love and how lonely that is. "No more small talk when the hunger's gone," this line reminds me of how when you go on a date or something and you're done eating, you don't just get up and leave...you might have a conversation with your lover, because eating dinner can also double as a social activity. Here, he's saying that dinner has become just another necessary life function, because even though he's done eating, dinner can really only consist of that. He has no one to talk to or love to make it anything else.
