What does the title the chocolate war mean in a literal and figurative sense?

In literal: It means your going to have war with chocolate.

In figurative: It could mean you might have to fight your temptations to better yourself.

Depending if its' a novel or fact or help book. The novel could involve romance and temptation. If it's a fact book it could be to help you with your chocolate habits or ways to cook it (a recipe book). Those are my interpretations but figurative is more opinionated.
