Unfortunately Burger King's "onion rings" are not onion rings; they are molded rings of batter flavored with some onion powder (which I don't seem to be able to taste, besides I don't eat onion rings for onion flavor but for the texture, which these molded rings completely lack).

onion rings by Orange. And one gets eaten by a dog.

Yes, you can eat onion rings on the Atkins diet. You will need
to remove the breading first.
