hi guys, any have a pot belly?! i'm 10% bf and when tensed my six pack shows, however when i relax my belly looks like a pot belly! it sticks out and my six pack no longer shows

i think its cause i eat alot so my stomach is full with food all the time, anyone know how i can get rid off a pot belly ? i thought i could maybe eat less so my stomach shrinks but i dont want to lose any size in my body. xmas hols and food never helps lol
