Alcohol is like the 4th macro that no one wants to think about.

As a general rule, the calories that come from alcohol sit somewhat between what carbs/protein and fats do.

Carbs and proteins run 4 cals per g. Fats run 9 cals per g. Alcohols generally run around 7 cals per gram.

One Budweiser (12oz) is about 150 cals. One shot of 80 proof Vodka is about 65 cals.

So, if you're looking to do the lower cal thing, go for a liquor (NOT something with a liqueur) with water or diet soda as a mixer.

BUT another thing to keep in mind (aside from how quickly those cals add up) is that the body tends to prioritize the processing of alcohol.

It's a poison. So naturally, your body is going to want to get rid of it as quickly as possible so that you don't die.

Therefore, any food you take in before your body's done ridding itself of the alcohol toxins, isn't going to be processed and absorbed like it should.

In other words, if you're going to drink, do it sparingly. And try not to eat a shit load of food while/after you've been drinking.
