It's called a meat based diet when most of your calories come from animal products.

Most of the world exist on a plant based diet, even if they consider themselves meat eaters.

You're right though, if you're eating any plants beyond herbs, spices & plant extracts (eg tea/coffee), you're not a carnivore.

I eat meat based but I'm not keto. I eat carnivore meals sometimes, but I'm not carnivore. Labels are purely for communication, you should avoid identifying with the labels.
