they always eat alot but what do they eat? maybe that one cow pokemon

they eat regular fish they have pokemon and regular animals though in one episode team rocket try to eat magikarp (and fails rather humorlessly)

I'm pretty sure they have other animals. I know they have fish, but I'm guessing they probably do eat a few, namely the cow.

off topic but I wonder how charazard taste...probably spicy

i would think they're hard to cook

What do you think happens to the pokemon that lose their battles?

nope, far as we know, aka the info we have, Pokémon are no longer served as food, at least not widely. some exceptions exist, like slowpoke tails.

I'd say all that meat is either: vegetarian meat substitutes - like soy and stuff; I have a veggie friend and he has stuff that looks just like actual meat but it's not and it's not bad at all, the taste isn't exactly meat like but it's good.

or

they have "real world animals" for that - we know they have RL animals in the Pokemon world, like fish and certain insects and etc.... maybe they have larger animals but just mantain them away from certain areas to keep them from interrupting the natural ways of pokemon and to protect them from pokemon, and that's why we dont see them

It is likely they eat the real world animals but there are pokemon that eat other pokemon such as ekans eating spearow or pidgey eggs or pidgeot eating magikarp. There are real animals that are predators to pokemon such as the mongooses that pray on ekans.

true, we know that from Pokédex entries. although I'd say that number is declining due to humans...
specially real world animals preying on ekans, I mean, Ekans has super powers!

I heard that Pokemon meat comes from Tauros

that's what the commies want you to believe

It's all Quorn!

@jorgevy: Exactly that makes you wonder how deadly mongooses are if they become predators to super powered snakes.

maybe the mongooses in the pokémon world are different? maybe bigger and stronger? a new breed?

Magikarp

They eat their dads to gain everlasting youth

Pokemon eat Pokemon.

They eat pokemon. In the show as well.

Miltank, grumpig and Torchics lol

Eponas are in the Growlithe food.

Soilent Green. Duh.

Magikarp isn't edible
