Exactly as KD says, you're having 810 calories a day. If you're sticking to that, then there is no way you can't lose. Your BMR can't possibly be below that. So just stick at it and I'm sure next week you'll see the results on the scales! If you don't measure yourself, you definitely should! There were weeks that I lost nothing on the scales, but lost a great number of inches. So you see, the scales don't say it all. You might have shrunk but gained muscle, and muscle weighs more than fat!
