For what it's worth, which may not be much, the idea that being an avid Cockatilian is somehow incompatible with being body-conscious is a canard that's quickly losing steam. We're not all slovenly slobs & soused sots in search of some sweet slack. (Not, in case it needs be said, that there's anything wrong with that.)
In fact, combining an active lifestyle, or even a strenuous workout regimen, with an appreciation of fine imbibage is not only possible, but even desirable. All that you as a future fitness freak & festivity fetishist need to know is what drinks are better than others for filleting your form to its finest.
I always thought beer & liquor and wine were all pretty much the same in terms of effect and intake, accounting for the different portion sizes, but according to this thread on Google Answers, gin should be the imbiber's bevvy of choice. G&T's, it seems, are almost guilt-free! (Honestly, though, unless you're having like nine of these things a night, none of the choices seem like a huge nutritional investment. In other words, it's not the booze, it's what the booze does to you that screws you up. (Mmmmm, cheese fries at 2am.))
(Yes, I know the link is almost seven years old. Our parents weren't even born when that thread was posted, but I'm guessing the nutritional value of things hasn't changed that much since the Clinton era. I'm willing to go with it. Calorie King concurs, and throws sake in as another alternative, which I'm all for. And if you want to get your hands dirty in the whats and hows, MedecineNet goes into great detail about how various alcohols work on the body. If, however, you just want a straight-up chart, this British site is fairly good.)
We at Cocktailians always advocate staying in control, even if we don't always (or, well, frankly, let's face it, ever) practice it ourselves. And certainly, if you're a type who's got 2% body fat and are obsessed with your lats and splecs and delts and reps or whatever, we're going to be stuck in smalltalkville for a long time if we meet at the pub. But we strive to be a full-service site, and it's important to include the more buff of youse in our great cocktailian equation.
