For anything other than kcal, you'll need to send a sample to a lab. By the way, it's illegal to put nutritional information (other than kcal) on beer labels.
Why is it illegal to put nutritional info on beer labels?

I'm firmly in the school that counting calories is bull, unless you're comparing a Big Mac and a cucumber salad. A better comparison is the content of what you're consuming and how well your body is built to process it.
In that regard, homebrewed and unfiltered beers do pretty well. Yeast has got some nice B vitamins that help ameliorate some of the nasty effects of alcohol. I feel refreshed drinking my brew, especially after a workout. I also never get much of a hangover. That says something.

I started counting calories at the end of last year. I'm a firm believer that counting calories is the most effective method of losing weight. Here's a chart of my weight so far this year:
I think you hit the nail on the head -- reducing caloric intake for one person is effective, therefore counting calories is an effective method of losing weight -- as long as you are reducing intake to a reasonable level based on your metabolism and exercise levels. Simply counting calories and lowering them to some standard level is just a random stab in the dark, and may or may not work.
Or, more simply:
Calories in >> Calories out = Weight Gain
Calories in == Calories out = Maintain Weight
Calories in << Calories out = Lose Weight
Personally, I find that when I stay away from red meat and eat lots of veggies, beans and whole grains, I can stay pretty slim regardless of how well I drink. Also, your Miller/Bud/Coors are lower in calories, but they've got a crapload of additional additives than your body needs to process. That can affect the rate at which your body actually converts what you consume into energy rather than just storing it in the gut. Homebrew has more calories, but I'm convinced it's much better for you than commercial beers, especially those villainous MBCs.
