I would think it would be the same for just regular coffee-- 0.6 carbs per 8oz (if I remember correctly). There was a thread on flavored coffees a while back. The consensus was most flavored coffees are okay too -- there are just a trace more carbs than regular coffee. From what I read, it's only chocolate flavored coffee you really need to watch out for and avoid due to the carb content. Of course, if we start talking Starbucks frappuchinos -- that a whole different story!

But for the breakfast blend, personally I'd drink it without worry.
