How Many Calories in a Can of Cola
Here's the number, straight away, followed by the context that actually makes it useful — including one NHS comparison most people find genuinely surprising, and a look at why every single one of those calories comes from the same place.

139

calories in a standard 330ml can of regular Coca-Cola

35g sugar 0g fat 0g protein 37g carbs

Figures based on Coca-Cola's own published UK nutritional information for Original Taste, 330ml.

Why Every Calorie Comes From the Same Place

Unlike something like a glass of milk, which delivers calories from a genuine mix of fat, protein, and natural sugar, a can of regular cola has a much simpler nutritional makeup: water, carbon dioxide for the fizz, colouring, acidity regulators, natural flavourings, caffeine, and sugar. That last ingredient is doing all of the caloric work essentially — there's no fat and no protein in the equation at all, which is exactly why the entire calorie count tracks so closely with the sugar figure rather than being spread across several nutrients the way a more complex food or drink would be.

What 35g of Sugar Actually Looks Like

Every gram of those 139 calories comes from sugar — no fat or protein is diluting the picture, as covered above. Since a standard sugar cube is roughly 4g, 35g works out to about nine cubes, or roughly seven level teaspoons, dissolved into a single can rather than sitting visibly on a spoon where it would look considerably more alarming.










Genuinely Worth Knowing

One Can Already Exceeds the NHS Daily Sugar Guideline

The NHS recommends adults consume no more than 30g of free sugars a day — meaning sugars added to food and drink during processing, plus sugars in honey and fruit juice, rather than sugars naturally occurring in whole fruit or milk. A single 330ml can of regular cola, at 35g, already sits above that entire daily allowance before you've eaten anything else at all that day. It's not a reason for alarm over one occasional can enjoyed alongside a meal, but it's a genuinely useful reference point to keep in mind if cola has become more of a daily habit than an occasional treat, since it can quietly account for well over 100% of the recommended daily sugar budget on its own.

The Size of the Can Changes the Answer

"A can" isn't always the same size in the UK, and the calorie count scales directly and predictably with volume, which is easy to overlook when reaching for whatever's available rather than checking the actual size printed on the can itself.

Coca-Cola Zero Sugar: 1 Calorie

The zero-sugar version of the exact same 330ml can contains just a single calorie, using sweeteners instead of sugar entirely to achieve a genuinely similar taste. We cover exactly how those sweeteners work, including a significant 2023 safety ruling on aspartame that's worth understanding, in our sugar-free soda alternatives guide.

Calories Aren't the Only Number Worth Checking

While calorie count gets most of the attention in these conversations, a standard 330ml can of regular cola also typically contains around 32-35mg of caffeine, added deliberately as part of the traditional recipe dating back to the drink's earliest formulations, rather than occurring naturally the way it does in tea or coffee. This is considerably less than a standard cup of coffee, but still genuinely worth factoring into your total daily intake if you're drinking multiple cans throughout the day, particularly later in the evening when even modest caffeine amounts can affect sleep quality for many people.

Frequently Asked Questions

Does Diet Coke have exactly the same calorie count as Coca-Cola Zero Sugar?
Both are effectively 0-1 calories per can and use sweeteners rather than sugar, though they're formulated with genuinely different flavour profiles and sweetener blends behind the scenes, which is exactly why Coca-Cola continues to sell them as two distinct products side by side rather than consolidating into just one.
How many calories are in a 500ml bottle rather than a can?
A 500ml bottle of regular Coca-Cola contains roughly 210 calories, scaling proportionally upward from the standard 330ml can figure, since the sugar concentration per 100ml stays consistent across every pack size the brand sells.
Is cola worse for calories than other regular soft drinks?
Not particularly — most regular, full-sugar carbonated soft drinks sit in a broadly similar calorie range per 330ml serving, generally somewhere between 130 and 150 calories, so cola isn't a notable outlier within that wider category specifically, despite often being singled out.
Does the NHS 30g sugar guideline include naturally occurring sugars too?
No, the 30g figure specifically refers to "free sugars" — sugars added during processing or preparation, plus sugars found in honey and fruit juice — rather than sugars naturally present within whole fruit, vegetables, or plain milk, which are treated quite differently within official UK dietary guidance.
Roughly how much walking would burn off one can of cola?
This varies considerably by individual body weight, walking pace, and overall fitness level, but as a rough general guide, a brisk 25 to 30 minute walk burns approximately the same number of calories contained in one standard 330ml can, give or take depending on the person.
Has the calorie count of regular Coca-Cola changed over the years?
The core recipe and calorie content have remained broadly consistent for regular Coca-Cola over recent decades, though the wider soft drinks industry as a whole has shifted significantly toward zero- and low-sugar reformulations following the introduction of the UK's sugar tax in 2018.
