Alcohol Calories Calculator — How Many Calories in a Drink

Pure ethyl alcohol provides about 7 kcal per gram — more than carbohydrates and protein (4 kcal/g each), and less than fat (9 kcal/g). It is the second most calorie-dense nutrient after fat, so alcoholic drinks significantly raise your daily calorie balance, even without sugar.

Alcohol calories are "empty" because they provide energy but virtually no vitamins, minerals or fibre. The body cannot store alcohol, so it prioritises it as fuel. The result is plenty of calories with no nutritional value and no feeling of fullness.

Half a litre of 5% beer is about 200 kcal, a 150 ml glass of 12% wine about 110–130 kcal, and 50 ml of 40% vodka about 110 kcal. Vodka has more calories per 100 ml but is drunk in smaller amounts. Sweet cocktails are often the most calorific due to juices and syrups.

The liver metabolises alcohol first as a toxin, pausing the oxidation of fat. For several hours the body burns mainly alcohol, while excess energy from food is more easily stored as body fat. That is why drinking makes weight loss harder.

Yes, partly. The calculator adds approximate carbohydrate calories based on the drink type. For the "cocktail" category it uses an average sugar content, but a real drink with juice or cola can have far more calories. For accuracy, check the mix ingredients.

Yes. Alcohol lowers self-control, stimulates appetite and encourages snacking on fatty foods. So calories from the drink are joined by calories from food eaten alongside. This is one reason evenings with alcohol can be a calorie trap in a diet.

A hangover stems partly from dehydration, low blood sugar and the build-up of toxic alcohol breakdown products. The next day people often reach for calorific, fatty meals and skip exercise, which further worsens the weekly calorie balance.

Usually yes. Non-alcoholic beer has no alcohol calories but still contains malt carbohydrates, and some are sweetened, so read the labels. Lower-strength drinks with no added sugar generally have fewer calories than strong, sweet equivalents.

Choose smaller servings and lower-strength drinks, swap sweet mixers for soda water, dilute drinks and take breaks. Alternating with water reduces the amount of alcohol and keeps you hydrated. Most effective of all is drinking less often.

No. Results are indicative and based on average values for the drink type. They are not medical or dietary advice. Alcohol harms health regardless of calories. For health, diet or addiction matters, consult a specialist.
