Cannot lose body fat/reach goal weight.

Hey there! I’m hoping someone in here can help me.

I cannot seem to lower my body fat percentage and I’m struggling to think what else I could do.

I’m a 32yo male, 5’2”, around 150lbs and usually between 15-20% body fat. I’m in good shape overall, and I’m crazy about tracking what and how much I’m eating. 90% of my diet is healthy and I allow 10% of my diet for indulgence and enjoying life bc we’re all gonna die anyway lol I’m also psycho about getting enough sleep to help. I haven’t been working out as much lately but even at my most disciplined, I couldn’t get to my goal weight. I’m a small guy, so I’m trying to be around 135lbs. Everything says I’m overweight but a lot of that is from muscle mass (I put on more muscle this past year than I actually wanted to, thinking it would help with the body fat). Instead I’m just beefy and I don’t wanna be this beefy lol

I’m trying to get below 15% body fat and my body just refuses. At my lowest and slimmest I was 126lbs but still jacked. I want that back, but at a more reasonable 130-135lbs. Could it be stress/cortisol holding onto the fat? I’m always busy and on the go. I’m a full-time shift supervisor and full-time student, and when I do have free time, I spend it taking food to hungry and unhoused folks because my work wastes tons of perfectly good food. But all of that is stressful stuff.

I’m just wondering what else I need to do because most days I’m in a deficit but still making sure what I get is as nutritionally complete as possible.

So I’m just at a loss and hoping someone with expertise in this area can help. Or is this a lost cause?
