Post OP weight loss?

I have a quick question. I have been on a slow-but-steady weight loss streak before my BA. Roughly 5kg (~11lb) in half a year, so nothing earth-shattering, but it was consistent and it was progress.

I read at least a few opinions that you should not lose too much weight after a boobjob, but I was looking forward to pushing the scale down another 5-10kgs. Will that be okay?
