Should i become vegetarian, and how should I tell my parents?

I used to like meat, but now i really don't find it appetizing anymore. I want to be able to become vegetarian, but am not sure how to tell my parents. I'm not sure if they'll want to cook different things. Also, i still want to be able to have things like pot stickers(dumplings) which have meat in them, and also soups with chicken broth in them. What should i do?
