[Left 4 Dead] Where do Boomers get their bile from?

Does the Green Flu infect someone, make them want to eat a lot and then turn them into Boomers? Or does it do it after they've become a zombie?

Remember that L4D zombies are technically still alive.

What you suggest might be somewhere in-between - maybe boomers are the only kind of infected that actually eat the people they kill, plus anything else that isn't nailed down.
