Does non-alcoholic beer have fewer calories than regular beer?

Yes. Alcohol is the biggest source of calories in beer, at about 7 calories per gram. Take it out and most of the energy goes with it. Heineken shows this well: the 5% Original has 42 calories per 100ml, Heineken 0.0 has 21.

Per pint the gap is larger. The NHS puts a pint of 5% beer at up to 222 calories. A pint of Enhanced Lager is about 97.

Where the calories come from

Once the alcohol has gone, nearly all the calories come from carbohydrate left over from the malt: starches, and some sugar. Carbohydrate carries about 4 calories per gram, against 7 for alcohol. A beer with more leftover sugar, such as Erdinger Alkoholfrei at 3.6g per 100ml, tends to sit at the top of the table.

The trace of alcohol in a 0.5% beer barely counts. A pint holds about 2g of alcohol, around 16 calories.

Calories in each IMPOSSIBREW beer

IMPOSSIBREW beer kcal /100ml kcal per 440ml can

Enhanced Hazy Pale 16 70
Enhanced Lager 17 75
Sicilian Lemon Lager 17.5 77
Pro Grapefruit IPA 17.5 77

Every IMPOSSIBREW beer is 0.5% ABV and brewed with Social Blend™. Enhanced Lager is gluten-free (under 20ppm) and vegan, with 0.7g of sugar per 100ml.

What to check on the label

Look at Energy, given per 100ml, and multiply by the size of the can: 4.4 for 440ml, 3.3 for 330ml. Then check of which sugars, because two beers with similar calories can carry very different amounts of sugar.
