Has anyone had any luck with the Atkins shakes? The bars seem to slow down my weight loss. The shakes, however, have only 5 grams of overall carbs with 4 grams of fiber for a net carb count of 1. This seems much more conducive to ketosis because the "sugar alcohols" aren't present like they are in the bars. Has anyone had a stall in weight loss or ketosis with the shakes like many people have had with the bars?
