Demuralist gave you the 20% protein numbers. I agree with her.
I was curious as to why you were eating 1200 cals, but that makes sense at your height.
FYI By the formula in the first post your goal is 54kg, so that would be 54g protein, 27g carb and 108 g fat allowing you 1296 calories. So if you feel you need a little more, I think you could add a little.
