Calories are only part of it. Alcohol also suppresses fat oxidation, blunts post-training muscle protein synthesis and degrades sleep quality.

What alcohol costs in calories

Alcohol supplies 7 calories per gram, between carbohydrate at 4 and fat at 9. A four-drink evening commonly lands between 500 and 800 calories, which for most people erases an entire day of deficit.

It is also the most commonly untracked category in any diet. People who weigh their oats to the gram routinely log nothing for a Friday night, and the weekly arithmetic quietly explains a stalled result.

Calories are not the whole cost. Alcohol suppresses fat oxidation while it is being cleared, blunts post-exercise muscle protein synthesis, fragments sleep and lowers dietary restraint. The number here is the visible part.

Frequently asked questions

How many calories in a night of drinking?

Four beers is roughly 580 kcal, four glasses of wine about 640, four cocktails potentially 1,400.

Which alcohol has the fewest calories?

Spirits with a zero-calorie mixer, at roughly 110 kcal per measure.

Does alcohol stop fat loss?

It does not stop it, but it suppresses fat oxidation while being metabolised and adds calories that are easily missed.

How do I account for drinking in a diet?

Track it, and reduce intake slightly earlier in the day rather than pretending the evening will not happen.
