do you know what your maintenance is? I wouldn’t go more than 250-300 cals below maintenance. especially with trying to grow muscle, you need to fuel your body properly so your muscles can actually grow. growing your muscles will also help lose fat since muscle burns more calories at rest than fat does.
if you’re in too large of a deficit, you can’t grow muscle as well and your energy will be super low. at some point your body starts compensating by slowing down your normal functions to conserve energy so you’ll start burning less calories naturally. a 250-300 deficit is a good in between where you can still build muscle while losing fat
