Guinness draft has fewer calories than skim milk!
A pint of Guinness has fewer calories than Coors and Budweiser and has more flavor than them. Guinness draft has fewer calories than a serving of skim milk, which has 135 calories. It also has fewer calories than a serving of orange juice, which contains 183 calories. Twelve ounces of Guinness contains only 125 calories.
Regular Budweiser contains 143 calories, Coors Original contains 148 calories, Sam Adams Boston Lager contains 160 calories, Anchor Steam Porter contains 205 calories, and Sierra Nevada Stout contains a whooping 225 calories.
Alcohol is the primary calorie culprit. Guinness has only 4 percent alcohol content while other stout beers contain 6 percent. Guinness has more plain water content, and actually their water comes from Wicklow Mountain springs. Their beer contains fewer proteins and dense sugars, as well as zero fat. They keep a special reserve of their beer under lock and key in case anything happens to their main supply.
