Beer has a fairly high calorie count - roughly between 150 and 300kcal per serving of 0.5l depending on kind. A significant percent of that is alcohol though, which is fully metabolized without any reserves whatsoever being retained - empty calories without actual nutritional contribution to organism.
I wonder what is the actual typical contribution of beer to human body energy reserves - energy from sugars, fats, proteins? How should I count beer in my diet?
