Are there any pills that make someone want to eat healthy food?

No. No, there is nothing that will accomplish this for you.
Never heard of any. The great desire we all have is a magic pill to fix whatever problem ails us. I guess the idea that a pill to make us eat healthy would be a great thing, but the idea doesn't pass my bs detector. Too many variables of lifestyle, taste, access and motivation make the idea farfetched.
