Beer gets such a freaking bad rap. Yes...everyone knows it's effects on protein synthesis, estrogen, decreasing testosterone, dehydration, etc....but that's when you OVER DO IT. Going out once a week and having a few beers won't hurt or kill you. I'd actually advise it unless your a competitive body builder. Going out and having a guys night or go out and bird dogging some women while drinking a few allows you to relax, hit the reset button a bit and unwind. Which, IMO (which has no scientific backing whatsoever), is GOOD for overall health. So...once a week...don't be afraid to drop a six pack.
I really find it hard to believe all the people on these forums who talk about "why drink at all", "it will hinder your gains", etc. actually practice what they preach. I LOVE beer, like seriously LOVE it. You just have to find a balance of being able to enjoy ALL the things you like in your life. Not having a few beers b/c it will "destroy your gains", or make you fat is absolutely ridiculous.
Have some fun on that cheat day bro...it'll do ya good! As for the short answer to your question LOL....CHOOSE BEER!
