A pint of lager contains somewhere between 170 and 260 calories, depending almost entirely on how strong it is. That's the short answer. The longer answer is more useful, because the difference between a session on Foster's and a session on San Miguel adds up faster than you'd think — three pints of the latter carry roughly the same calories as a decent lunch.
Below we've compared the big UK lager brands pint for pint, explained where the calories actually come from, and looked at the easiest ways to trim them without giving up the beer.
Where the calories in lager come from
Beer has two main calorie sources: alcohol and carbohydrate. Alcohol is the big one — it carries about 7 calories per gram, not far off pure fat at 9, while carbs manage only 4. In a typical lager, well over half the calories come from the alcohol itself, with the rest from residual malt sugars left after fermentation (we've covered those separately in our guide to carbs in beer).
This is why strength predicts calories so reliably. A 3.7% lager simply cannot carry as many calories as a 5.1% one, whatever the marketing says. It's also why "premium" lagers — which in Britain usually just means stronger — sit at the top of the table below.
Calories in a pint: the big UK lagers compared
The figures below are calculated from each brewer's widely published per-100ml numbers, multiplied up to a 568ml pint and rounded. Treat them all as approximate — recipes and strengths change, so check the label or the brewer's website for the current figure.
| Lager | ABV | Approx. kcal per 100ml | Approx. kcal per pint |
|---|---|---|---|
| Foster's | 3.7% | 30 | 170 |
| Carlsberg Danish Pilsner | 3.8% | 31 | 175 |
| Carling | 4.0% | 33 | 190 |
| Birra Moretti | 4.6% | 38 | 215 |
| Madrí Excepcional | 4.6% | 39 | 220 |
| Stella Artois | 4.6% | 40 | 227 |
| Peroni Nastro Azzurro | 5.1% | 42 | 240 |
| San Miguel | 5.0% | 45 | 255 |
A few things jump out. The bottom three slots are occupied by the weakest beers, exactly as the alcohol arithmetic predicts. The fashionable "world lager" brands — Peroni, San Miguel, Moretti, Madrí — cluster at the top because they're brewed (or at least badged) at continental strengths. And the gap between the lightest and heaviest is about 85 calories a pint, which over a four-pint evening is the difference of a whole extra pint of Foster's.
For the record, a pint of Guinness sits at around 210 calories — comfortably mid-table, and lighter than most of the premium lagers above it. The idea that dark beer is the heavy option doesn't survive contact with the numbers.
What that means in practice
Numbers per pint are one thing; a night out is another. Three pints of Carling come to roughly 570 calories. Three pints of San Miguel come to about 765 — approaching a third of a typical adult's daily intake, before anyone's ordered chips.
It's worth saying that lager's calories aren't uniquely wicked. A pint of standard lager has a similar calorie count to a large (250ml) glass of 13% wine, and rather fewer than many creamy cocktails. Beer's problem is volume and repetition: nobody orders four large wines out of politeness because it's their round.
Bottles and halves shift the maths usefully. A 330ml bottle of Stella is about 132 calories; a half of Peroni around 120. Same beer, smaller dose.
How to cut the calories without cutting the lager
- Drop half a percent. The single most effective trick. Swapping a 5% world lager for a 4% standard saves 50 to 70 calories per pint with no change to how the evening goes.
- Order halves or two-thirds. Increasingly normal in craft bars, and it means you can try more beers for fewer calories — the tasting-flight approach.
- Go alcohol-free for some rounds. Most major lagers now have a 0.0 version at roughly a third of the calories of the original. The quality has improved beyond recognition in the past few years.
- Watch the "light" labels. Lower-calorie lagers are usually lower-alcohol lagers by another name. That's fine — just know that's what you're buying. We've ranked the best of them in our guide to the lowest calorie beers in the UK.
One thing not worth doing: switching to lager from other beer styles purely on calorie grounds. Style matters far less than strength. A 4% bitter, a 4% pale ale and a 4% lager are all within a few calories of each other — if you're weighing up the differences, our guide to what actually separates beer and lager covers it.
The bottom line
A pint of lager costs you roughly 170 to 260 calories, and you can predict where any given brand falls just by reading the ABV on the tap badge. Weaker equals lighter, almost without exception. None of this is a reason to give up the pint — it's just worth knowing that the choice between brands is quietly a choice between calorie counts too. Interestingly, the modern craft lagers taking over UK taprooms tend to sit at 4.0 to 4.8%, right in the moderate middle of the table.
All figures here are approximate: brewers reformulate, strengths get trimmed, and the label in front of you always beats a table on the internet.
Walk it off between taprooms
Here's our completely biased suggestion for offsetting a pint or two: earn them on foot. Our brewery tours typically cover a few miles of city walking between breweries and taprooms, with tastings poured by the people who made the beer — it's the only calorie-management plan we know of that ends in a taproom. And if you'd rather give one than book one, our gift vouchers are delivered by email and never expire.
