I've just heard from some people (yourself, BodyByFinaplix, and proteinfiend) claiming that it's okay to mix fats and carbs. I've heard many more times over, though, that mixing these two together can be a very bad thing. Or is, not can be. I've heard that from Swolecat and JohnBerardi's website. Many other times as well, but I forget when since it's been a long time.
