Yes new studies have come out indicating you can gain muscle while in a deficit. However it would require 0.8g of protein/lbs of bodyweight, adequate training and frequency, and you sleep, rest, etc to be lock in as well. Another issue with this is your hormone profile won’t be what it could be if you were in a surplus and chronic dieting can lead to a crushed hormone profile. All in all I’d recommend just trying to grow tissue while at maintenance since as you gain muscle and keep the same -
It’s possible but would require real experience in the gym and an overall healthy lifestyle. So what I’m trying to say is if you haven’t been already been lifting for a few years and spent a good amount of time learning what’s required of you outside of the gym to grow muscle, I’d stay away from it. So, I’d recommend cutting down to 15% bf if you over it and maingaining from there. You can bulk if you want but other than hormonal issues I personally don’t see much benefit in putting yourself-
