They would rot before they ever died of hunger... they're dead so their organs wouldn't process nutrients from the food they eat.Amnestic said:Of course, that's assuming we're working in the universe where zombies do die off eventually from lack of food.
If you're thinking of 28 Days Later remember, those were infected but still living humans that forgot they needed food because of the infection.
Don't get into the argument of how they'd still be able to walk around without nutrients sustaining their muscles and such because well, they're fictional monsters.
