Just stumbled across this: http://getdrunknotfat.com/ . It was on the internetz, so take with the appropriate amount of salt. YMMV.
Sweet, the sixer of Sierra Nevada Summerfest that I crush when I get home from work on Friday is only going to cost my 1,000 calories! Interesting how high in calories all those "malt-ernatives" are. Gross and bad for you, yikes.
