Real life zombies (if they worked like the ones in movies) would all starve in the first month.

Imagine if lions eat a few kg of meat from an anteople, and then the rest of the antelope turned into another lion.

If zombies catch you and eat you, you're gone. If zombies catch you, bite you and you escape, you become a zombie. Generally it's not both at once.

xkcd estimates that in a similar case humans would survive 32 months: https://what-if.xkcd.com/105/
