get rid of the protein bar for one if you are serious about getting lower bodyfat.. although IMHO I feel that you dont need to loose more, although I do not see pictures... what is your reason for wanting to be so lean? If you are having such difficulty at this point getting that lean, does it not make you wonder how much more difficult it will be to maintain at that % ? Just a thought.
have you done any days with higher carbs and calories? sounds as though your body may need a shock.
