Silk brand creamer adds a nice flavor... almond milk is pretty good, but I don't think it's creamy enough for coffee. I agree with untouchable that it's unlikely that a little bit of creamer (maybe 2 teaspoons, dry) will hurt your weight loss goals. In fact, soy may be more counter-productive with your weight loss--since it's been shown to disrupt thyroid function (and one of the hallmark symptoms of an underactive thyroid is weight gain that's otherwise unexplained).
