Adding any amount of milk to a coffee adds carbs. And a large number of people add _some_ amount of milk.
People tend to add single or double cream (1/2 & 1/2 or whipping / heavy cream, respectively, in the US) to coffee, both of which have less carbohydrate, and generally add a tablespoon or two (15--30 ml) per cup of coffee. The carbohydrate content is < 2g.
That's unlikely to bring someone out of a ketosis state, which requires a daily intake of < 15--30g. That's about two full cups (450 ml) of single cream.
I never looked before today, but always thought it was the other way around.

Also neat to know.
I only know the impact that a Dunks coffee (with cream) has on my blood sugar (and how much insulin I need to take to counteract it). So this has been a learning experience for me. Thanks
