I think it was hinted a long time ago that ghouls are meant to fight and eat each other and recently Nishiki said that the fast aging process of Kaneki can be slowed down by eating ghouls. And there is Kakuja a form that can only be archieved by eating other ghouls. Perhaps human meat alone is unhealthy food for them, making them weaker, age and die faster.
