How Many Calories Are in Alcohol? A Drink-by-Drink Guide

Alcohol itself provides 7 calories per gram — almost as much as fat's 9 calories per gram, and more than double what protein or carbohydrates provide. Because those calories are easy to overlook, alcoholic drinks can add up to a significant chunk of daily intake without feeling like 'food.'

Calories by drink type

A standard 12 oz beer runs roughly 150 calories, while light beer is closer to 100-110. A 5 oz glass of wine is typically 120-130 calories. A standard 1.5 oz shot of distilled spirits (vodka, whiskey, gin, rum) on its own is about 95-100 calories, but mixed drinks and cocktails can run 200-400+ calories once mixers, syrups, and juice are added.

Why alcohol calories count differently

Alcohol has no nutritional value beyond calories — no protein, fiber, or meaningful micronutrients — so it doesn't contribute to fullness the way food does, which makes it easy to drink several hundred calories without feeling physically satisfied. Alcohol also temporarily shifts your body's priorities toward metabolizing it first, which can slightly reduce fat burning while it's being processed.

The mixer problem

Mixers are often where a 'light' drink turns heavy: regular soda, juice, and sweetened syrups can add 100-150+ calories to a single cocktail. Swapping to soda water, a splash of juice, or a sugar-free mixer can cut a drink's calories substantially without changing the alcohol content.

Tips to reduce alcohol calories without quitting

Choose lighter options like light beer, dry wine, or spirits with a low-calorie mixer; alternate alcoholic drinks with water to naturally slow consumption; set a drink limit before you start; and be mindful that alcohol also tends to lower inhibition around food choices later in the evening, which can add calories well beyond the drink itself.
