Q: Are alcohol calories any different than other food calories in terms of weight management goals?
A: A calorie is a calorie is a calorie. It doesn't matter what its source.
But also not so much. Alcohol is ultimately a poison, and upon its ingestion your body's number one priority becomes GET IT OUT (this becomes more urgent as alcohol levels increase, which is why vomiting and diarrhoea can both follow or occur during a night of drinking).
It's common knowledge that our poor livers get the worst of it, but not many people understand the roles the liver plays in helping our bodies regulate our immune systems, blood glucose levels, and helping decide what nutrients to use break down now vs what needs to get stored for later. Because alcohol sort of hijacks liver functions, the liver doesn't do as good a job at signalling when to draw on adipose tissue for energy and keeping blood-glucose levels where they should be. Alcohol can also damage pretty much every part of the GI tract with which it comes in contact, which can leading to nutrient absorption issues.
There are 7 calories per gram of alcohol, which makes it more calorically dense than a gram of either carbs or protein (4kcal/g). Then add the calories from the simple sugars that typically saturate alcoholic drinks, and you're basically drinking the caloric equivalent of a whole meal (assuming you're having a couple of drinks). As far as weight management goes, that will certainly throw off your daily calorie goals if you don't "budget" those extra calories in.
