On average, regular beers contain 145 calories and 11 grams of carbs per 12-ounce serving, but these numbers can vary. For example, Heineken has 166 calories and 9.8 grams of carbs, Budweiser has 143 calories and 10.6 grams of carbs, and Miller Genuine Draft has 143 calories and 13.1 grams of carbs.
Most "low-carb" beers vary between 95 and 110 calories, and contain between 2.6 grams and 6.6 grams of carbs per 12-ounce serving. But don't be fooled by the "light" label, Michelob Light has just as many calories and carbs as regular beer.
