Olive oil to cook?

I need advice, I use olive oil to marinate my protein to cook it (usually in the air fryer) and I fear I’m consuming a lot of calories because of the olive oil. What does everyone use to marinate their meat? Spray before seasoning? I’m European so the thought of not adding olive oil to everything I eat is weird 😂but I started calculating my calories and between cooking and salad dressing I’m consuming close to 600 calories just from olive oil
