Hi Sophotia,
I was on Protein Power and then switched to CAD. My experience with CAD is a slow one. It was slow with the other plans too. That has more to do with my age and the medications I need to take. I am resigned to slow.
Do you know if you are a Carb Addict? Have you taken the test for this yet? The thing about being an addict is that your system is not going to do really well on any plan (other than CAD) because of insulin release. You release insulin on Atkins pretty constantly if you are snacking pretty constantly. If you are an addict, you release more insulin then is normal and the snacks are hoarded instead of flushed. That equals a stall or very slow loss.
If you know already that you are an addict then you should try CAD and see how you feel. For most of us, the relief at not "needing" to eat all of the time is fantastic and the Reward Meal helps us cope with a long term change in eating habits.
If you are losing slowly anyway, give CAD a try. You might still lose slowly but you will have the happy addition of a Reward Meal (which is really nice with the holidays coming up).
Good luck and let us know what you decide.
