I don't have the best genetics. Even at the lightest I have been in all my adult life (157 lbs), I still had a (small) gut. I don't think I'll ever have a six pack 
When I gain weight, my arms get bigger (good), but so does the gut (bad).
When I lose weight the gut shrinks (but doesn't disappear) and so do the arms.
