Your only choice in the matter is whether you suck it in whenever people approach or flaunt it like the wacky uncle who slaps his belly and boasts that "it all turns to penis after midnight."
The beer gut doesn't exist. Or rather, that massive mound you insist on calling your "one-pack" has nothing to do with actual beer consumption. Says who? Says science.
"Maybe we shouldn't have gotten liquored up before this test."
You see, some researchers got curious about this whole beer belly thing a while back, but presumably their stingy bosses wouldn't sign off on a never-ending supply of oat soda "for science." So they rounded up a 2,000-strong bunch of Czechs, a people who apparently wean their toddlers off of the bottle by offering them a nice stout. And what they found was at once surprising and freaking awesome: Beer appears to have absolutely nothing to do with the so-called beer gut.
In fact, research shows that the amount of beer you drink and the size of your belly have no correlation whatsoever. Hell, if you keep your beer intake under even a modicum of control, chances are it doesn't even do that much to your general weight gain.
So try an all-beer diet -- the worst that can happen is scurvy.
