Point 6 could be replaced with something like, eating brains boosts your regeneration for some time; allowing them at the same time to regenerate enough muscle tissue to pry things faster and move slightly faster, and heal some brain damage, all those temporarily.

It gives incentive to actually eat people, if you're injured but your regeneration is too slow at the moment, eat that clown.

And, if not eating brains for a long time, you accumulate brain damage up to a point where you just wish you had a brain to eat right now.
