I think your rate of loss is ok, too...but.....one thing I have learned from this forum is to get 20 carbs a day -- fewer carbs won't help you at all.

Make sure you get all your vegetables and eat other carb containing foods (cream, cheese, Splenda, etc.) so that this WOE is healthy AND enjoyable. This WOE is not deprivation - it is about giving your body what it really needs. Don't deprive yourself unnecessarily.
Best wishes!
