I want to start by saying alcohol is a toxin and has no nutritional value and is just empty calories.
It can cause you to overeat when you get back late at night, cause you to be lazy the next day, dehydrates you, impairs your judgment, and protein synthesis and testosterone will decrease.
If you are of age and do drink, this is how you can account for alcohol.
There are 7 calories per gram in alcohol. (Carbs have 4, Fats have 9, and Protein has 4)
However, since this is not a macronutrient, you can use carbs or fat to calculate it.
You can do so by tracking it as 100 calories. If you want to track the macros you can do so by tracking it as 25 grams carbs (There are 4 calories in a carb so you take the 100 divided by 4 to get the 25 grams of carbs) or 11 grams of fat. (There are 9 calories in fat so you take the 100 divided by 9 to get the 11 grams of fat)
Or you can track it as 14 grams of carbs and 5 grams of fat.
This is all assuming that you are drinking beer or a shot or mixer with a zero-calorie chaser. (Side note: Distilled Vodka will filter through your body a little bit easier than other types of alcohol)
You have to keep in mind that cranberry juice or Sprite will include a lot more calories on top of that 100.
Those are unnecessary calories and carbs that can easily be avoided.
I would recommend getting an idea of the number of drinks you are planning on having and accounting for it during the day.
I usually try to stick to mostly protein on days when I know I’m either going out for dinner or having a few drinks. I usually keep my carbs and fat relatively low on those days.
Will alcohol make you fat?
Technically yes the mechanism of alcohol will get the main focus so food consumed with it will not be the main focus when getting metabolized.
However, if your total calories are in good shape and you account for alcohol, you shouldn’t have a problem!
