Does Warwick eat people?
We know he kills them but does he om nom nom? [sg-poppy]

The machine on his back seems to be capable of regenerating his cells, but it has to either be getting that mass from somewhere or it has to be creating that mass magically. So either the machine on his back can create mass from the mana in the air around him, or he has to be eating something. As far as I know there aren't many food sources in Zaun that are naturally occurring and I doubt he partakes in commerce.
So basically, he probably eats people if the machine that Singed implanted in him can't sustain him.
Read his lore. After he "escaped" from Singed's lab, he ate a bunch of people. http://leagueoflegends.wikia.com/wiki/Warwick
You can just link to the universe page.
It's hard to say whether he actually eats them though. We know he hunts people and he gets blood on him but does he actually eat them? It's like a cat chasing a mouse. The cat kills the mouse and they get the mouse's blood on them but the cat won't eat the mouse because they have their own food at home.
Ok, where does Warwick find food then? Tbh, I don't see him go shopping at a grocery store.
Maybe? Does Warwick even need food? That's a good question lol c:
I like Zezockary's answer tho.
Gotta feed the beast ya know? 
There's plenty of rats to munch on I bet.
