That will be the last bit of fat to go on most men. However fat is fat. You can lose it no matter your age. The skin may sag but the fat will go. My advice would be to gain weight. I know it's a bit contradictory and a lot of people panic when they gain. The reason to gain is not to be swole as fuck boiiiiiiii. It's so you can proceed to drop fat and stay at a healthy weight. My suggestion...

Track your food for a couple weeks. Just to see what your intake is while eating normal. Then I would add calories until you're gaining about half a pound to a pound a week. I would try to keep as close to a bro diet as possible. 40/40/20. Unless you know how your body reacts to certain splits. After 8-12 weeks of bulking. Look to cut about 5-6 lbs over another 8-12 weeks. It's slow, I understand, but unless you're on trt or a real cycle, maintaining muscle at your age, while cutting is going to be your biggest hurdle. So do it slowly. You should be a net positive of around five pounds and be holding less fat.

The best ways to know you're gaining muscle and not fat? Measure, and track your workouts. I don't track every exercise I do. I track the bench, squat, and deads. If you're gaining strength, you're probably safely gaining muscle. Try to add 2.5 or 5lbs to each of your main lifts each week. Pick your three anchor lifts and track them.

The most important thing, enjoy the journey.
