Is It Safe to Lose Weight After Rhinoplasty?

I am an 18 year old female and had Rhinoplasty 3 weeks ago, and I've got a holiday coming up in a couple of weeks and would like to lose a few pounds. I am in the healthy weight range but would still like to lose a little weight, mainly because I put quite a bit in in the last few weeks and don't like the fact that I suddenly can't fit into all my shorts. Would it be safe to do this? Would it increase the risk of infection or harm my recovery? Thanks so much for taking the time to answer these.
