Catrin - if you are still lifting and eating enough protein, even really low calories for awhile won't hurt your muscle much. Your general diet is such that you are already likely a 'fat burner'...so you are probably OK. I'm currently eating low calories, lifting and I haven't lost any muscle in the past month. Since your diet is so similar to mine, my guess is that you should be fine.
