Believe it or not, alcohol is a macronutrient based on the fact that it contains calories. Each gram of alcohol contains seven calories. Yes, you read that right. SEVEN! This is why it's so important to keep track of alcoholic beverages that you consume. It's important that you don't only account for the "empty" calories, though. "Empty" is in quotations because they're not really empty like we've been told. Sure, alcohol itself does not contain proteins, carbs, or fats, but alcohol can act like a carbohydrate or fat when it's metabolized. So, this is what we recommend: take the calories in your drink (in the liquor or beer) and account for them by using carbohydrates, fats, or a combination of both. You are free to choose where those calories go.
So, if you drank a 100 calorie light beer and you wanted to use some carbs, all you'd need to do is divide 100 calories by 4 (carbohydrates contain 4 calories per gram). Therefore, your light beer would take up 25 grams of carbs and 100 calories in your food log. If you wanted to use fat, just divide 100 calories by 9, and you have roughly 11 grams of fat. If you wanted a combination of carbs AND fats, just decide how many grams of carbs and fats can fit into your allotted macronutrients. If you wanted 10 grams of carbs, you'd have 40 calories accounted for, which means the other 60 calories (6.7 grams) could come from fats.
This concept came from Dr. Layne Norton and has helped many at Poehlmann Fitness enjoy their drinks while reaching their goals.
Long story short, be smart but DO NOT restrict yourself harshly. Track your macronutrients, enjoy your food, and live freely!
