its gonna be impossible to get rid of it all if you are like most males whom the stomach is the last place fat is stored especially as you age!!!.. you would have to drop your body fat literally to 5% or less to get rid of it all. i was 6% body fat when i was a runner and i couldn't find a piece of fat on my body, but my stomach did have a little bit i could still pinch. i am now 13% or so and my body barely has any fat but my stomach and inner upper leg i can pinch some fat.
i wouldn't stress out too much over it, you look good bro i've seen your pics.. you are being way too tough on yourself and looking for perfection which is awesome but at the same time you have to be realistic.. you do need SOME fat on your frame
