Yes. The first phase of Atkins is this "induction" ketogenesis phase. My guess is if you follow the diet rigorously, you don't need the strips at all, but for me at least, it is nice to have a external confirmation that I am in the ketogenesis zone. They turn a shade of colors and the side of the vial has a scale. The strips (Ketone Care) are really targeted towards diabetics and so which color on the scale they are may be more important to diabetics. I've been hitting "moderate" to "large" and I am happy with that place and level of precision. Also, they make great little bookmarks even after they've been used.
