Hello guys Ive been lifting for some months now and trying to eat ealthy. However Im kinda divided in what I should be doing. Should I get rid of fat or eat more to build size? I still have a belly and its been really hard to get rid of it. Might have something to do with having been obese? My height is 173cm and I weight 70kg but a few years ago I weighted 125kg. I lost 55 kg without lifting so I kinda think that fucked my metabolism. Im eating around 2000kcal (maybe Im miscalculating?) and lifting 3-4 days/week but my body hasnt changed that much since a couple of months ago

Thank you for your time
