Nicole,
I haven't lost anything really since the very beginning either. I was starting to get really discouraged (I even went out and bought those ketosis strips to make sure I was doing it right!) until this morning when I took my measurements again. Even though I haven't lost weight, I've lose several inches.
Did you take your measurements when you started? I've always heard people say to do this when dieting because sometimes the scale doesn't reflect the fat that is disappearing but never really believed it. Just a suggestion, it might make you feel better until the scale starts to move again (it will!).
I have to admit, I'm still really annoyed with my scale for not reflecting all of my hard work! Like you, I have not cheated yet. (Well, I had one incident where I ate something that I thought was okay without looking at the ingredients and as a result gained back 4 pounds! I won't make that mistake again!!) I'm really uptight about following the rules EXACTLY and feel I deserve some payoff!
