A good rule of thumb is: 1 Guiness Stout = 1 twelve-pack Michelob Ultra.

"If you already like "light" beers, you'll be fine with the lower carb options there. But if you don't care for them, thinking they are too "watered down", you might want to look at something like a Guinness Stout. As odd as it seems, draught stouts’ carbohydrate amounts don’t measure up to their mouthfeel. Guinness draught stout contains about 4% alcohol by volume, contains about 120 calories per 12-ounce serving and has roughly 5.2 grams of carbohydrate" (data taken from Stout by Michael J. Lewis; Brewers Publications, 1995).
