Ultimate guide to how many calories and units are lurking in Britain’s best-loved beers and ciders… so how bad is YOUR favorite?

Whether you’ve ditched the booze altogether or just embraced a “humid” January, you’ve probably cut thousands of calories from your diet without even realizing it.

That’s because beer and cider are notoriously bad for our waistlines, with some of Britain’s best-loved bottles and cans containing up to 290 calories.

For reference, that’s significantly more than a Krispy Kreme donut (195 calories) or two KitKats (104 calories).

And liquid calories are no different from solid calories: all types of calories make you fat if you consume too many of them.

‘It’s true that in the case of beer and cider the main health issue is the alcohol content,’ says Dr Duane Mellor, a registered dietitian at Aston University in Birmingham.

‘But it’s worth noting that a pint of some beers can contain more calories than two slices of bread.’

Each gram of alcohol contains about 7 calories, which means the heavier the beer, the worse for your waistline.

For comparison, a gram of fat contains about 9 calories, while carbohydrates and proteins contain around 4 calories.

In addition to the calories, some ciders can contain as much as five teaspoons of sugar, while a 330ml can of Old Mount Strawberry and Apple cider contains 18 grams.

To put that into context, the NHS recommends consuming less than 30 grams, or seven teaspoons, each day.

Dr. Mellor warns that some ciders can be the equivalent of drinking a sugary soft drink.

For example, a 330ml can of Fanta Orange contains less sugar than some ciders with 15 grams or four teaspoons of sugar in one can.
