There's a lot more to atkins than just cutting out carbs. Post what you've been eating and maybe some of the more senior members can comment. 3 days on Atkins and some people MIGHT be seeing changes, but everyone is different.

day 3 is when i notice a pd or 2 and after about 1 week 4-6 pds

I'm told the big weight loss you would usually see at the beginning is water weight so as you have already lost that you may not see such a big difference, but you should still be able to lose more weight. I lost 4 lbs in my first week. I am expecting it to slow down to about 2-3lbs a week now and after induction. As you said it is only day three, I'm on day ten. I weigh in every Friday and sometimes do a sneaky weigh on Tuesday while my bf is at work, lol, but I don't record that one.
