Looks like most regular beers are 5% alcohol, while light beers come in around 4.2%. Calorie counts are around 140, with light options around 110g. In carb counts, regular pilsners (Bud, Coors) come in around 10g, the light options around 5-6g (Bud Select is down to 3%). Some of the heavier beers are much higher. Sam Adams and Guiness are at 18g.
The bottom line: the thicker, heavier beers are worese for you. Who would have thunk it?
