Right now I'm around 80kg and 15% bodyfat. My arms, shoulders and chest have grown quite a lot, same for my legs. My face isn't chubby, but I have some fat stored on my cheeks, not too much, but I was wondering how much it would increase my SMV if I cut down to 10-12% bodyfat.

I've been reading stuff and apparently sodium retention and cutting down on carbs is a thing.

Is it worth giving up some muscles for a leaner face with a defined jaw line?
