Lisalaura, have a look through this thread, it should allay your fears -

Ketosis = fat loss?

Those ketostrips aren't very reliable, nor are the a good indicator of fat loss. You're probably in ketosis and just not registering - it happens to a lot of us. How much water you drink and whether or not you exercise will greatly effect your results.

If you're doing everything right and are sure that you're eating enough your slower than 'average' fat loss can most likely be attributed to being relatively close to your goal weight. Give it some time; slow losers are still losers.

Hang in there

P.S. I saw your post in another thread after reading and answering this one. Your comment there helped me to answer your question here: http://forum.lowcarber.org/showthre...6430#post286430
