I tried to access my college library for info on this but I'll have to wait until next month to get the articles I found since it is the end of the term. From what I read from several abstracts is that protein sparing diets themselves are the cause of not losing lbm and the less you weigh, the less your body needs just to get around. So, it you maintain the amout you have now, it will be a good amount for your goal. On a low fat, high carbohydrate diet you are more apt to lose lbm. I will put in requests for the articles but I won't be able to get them until the next term starts.
