When counting calories, people sometimes forget to take into consideration the calories in the beverages they drink. Depending on the type of beer you choose, the calorie content can vary considerably. While most of the calories in beer come from the alcohol, which provide 7 calories per gram, beers that are higher in calories also tend to be higher in carbohydrates.
