I don't know if it's too late to reply to your question, but I have had the same problem and this is what I read in the Atkins book.
It says that when you lose weigth and the then your reach a plateau, it could be because of different things, dairy is one problem if you eat too much, not drinking enough water and not sticking to the low carb.
But this is what made the most sense to me from the book.
When we lose a certain amount of weight, it takes time for our body to adjust to the weight loss, especially if we've been at that weight before. OUr body stalls to continue losing weight until it gets used to it and it make take as long as three to four weeks, which is what happened to me.
I kept thinking if I did anything to stop my weight loss, but I knew I didn't. So finally after the fourth week came I finally lost five pounds. I recently went to another plateau, and this morning I weighed myself and lost four pounds, this took another four weeks.
But better to lose than to gain. So I kept encouraging myself because I had lost 24 pounds and now another four.
So don't give up, just keep doing low carb and before you know it you will lost weight. If it's not weight we're losing, it will be inches, so don't forget that too.
1 Corinthians 15
1Moreover, brethren, I declare unto you the gospel
which I preached unto you, which also ye have received, and wherein ye stand;
2By which also ye are saved
, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3For I delivered unto you first of all that which I also received, how that Christ died for our sins
according to the scriptures;
4And that he was buried
, and that he rose
again the third day according to the scriptures:
