Of course, alcohol has calories, 7 per gram. But there are many substances which have internal energy but are not digestible by humans. For example, if I burn beeswax, I'll release lots of energy, but if I eat it, I think it won't count towards my caloric intake.
I've seen diet information sources which warn about the calories present in alcohol, but I have never seen a nutrition label which lists the calories from alcohol. It is also not considered a macronutrient in the classic "proteins, fats, carbohydrates" list. While I get it why nobody would suggest that alcohol becomes a regular energy source in the diet, I had the impression that those three are an exclusive list of compounds the body can use to gain energy. I find these contradictions confusing.
So in the end, are the calories from alcohol utilized by the body, or not?
