Well, I'm the one that is on the atkins/coffee plan. The coffee does nothing to aid weight loss, and there is recent research that shows it does effect insulin production. While on this WOE I've found that Dr Atkins had good reasons for everything he put in his books, even though he didn't fully explain them.

While I have had great success on this diet while drinking my black coffee every day, I cannot say if my weight loss would have been faster or slower without it. If you can, I would suggest breaking the habit.
