Clarifying the 33ml vs. 330ml Can Discrepancy
The most frequent and standard can size for Coca-Cola in many parts of the world, especially Europe, is 330ml, not 33ml. The question regarding "how many calories in a 33ml can of Coke?" is based on a common typographical error. A 33ml can is not a standard retail size for soft drinks and would contain a minimal amount of liquid, and therefore, very few calories. For context, 33ml is just over one fluid ounce, whereas a standard 12-ounce can in the US is 355ml. It's the 330ml can that most people are actually consuming, and whose calorie content needs to be considered when monitoring dietary intake.
The Real Answer: Calories in a Standard 330ml Can of Coke
For a standard 330ml can of Coca-Cola Classic, the calorie count is approximately 139 kcal. This energy is derived almost entirely from its high sugar content, with a single can holding about 35 grams of sugar. To put this in perspective, health guidelines often recommend limiting daily intake of added sugars, and a single can of Coke can provide a significant portion of that limit. The nutritional information per 100ml is 42 kcal, which shows how the calorie count scales up with the total volume. This is a crucial detail for anyone trying to manage their calorie intake, as these 'empty' calories offer no nutritional benefit beyond providing a quick energy boost.
The Nutritional Breakdown of Coca-Cola Classic (per 330ml)
Beyond just the calories, it's important to understand the full nutritional profile of a can of Coke. The primary components are sugar and water, with a few other additives for flavour and colour. Here’s a breakdown of the key nutritional elements in a 330ml can:
- Energy (Calories): ~139 kcal
- Carbohydrates: ~35g
- Sugars: ~35g (all from the carbohydrate content)
- Protein: 0g
- Fat: 0g
- Fibre: 0g
- Sodium: Minimal (less than 10mg)
This composition highlights that drinking a can of classic Coke is equivalent to consuming a substantial amount of sugar without any accompanying protein, fat, or fibre. These are considered empty calories because they contribute to your total energy intake without providing any essential nutrients.
Calorie Comparison: Classic Coke vs. Zero-Calorie Alternatives
For those looking to reduce their sugar and calorie consumption, Coca-Cola offers several alternatives with significantly different nutritional profiles. Both Diet Coke and Coke Zero contain zero calories and zero sugar, replacing the sugar with artificial sweeteners.
Different Coca-Cola Variants and Their Calories
- Diet Coke (330ml): Contains 0 calories, making it a popular choice for those on a diet or managing their sugar intake. Its sweetness comes from artificial sweeteners like aspartame and acesulfame potassium.
- Coke Zero (330ml): Also contains 0 calories and 0 sugar. It is formulated to taste more like Coca-Cola Classic, using a different blend of sweeteners compared to Diet Coke.
- Caffeine-Free Coke (330ml): The calorie content is similar to Classic Coke, around 140 calories, as it contains sugar but simply removes the caffeine.
Switching to one of these variants can drastically reduce the amount of sugar and calories consumed from soft drinks, offering a way to still enjoy the flavour without the caloric cost.
The Health Implications of High Sugar Intake
Regular consumption of sugary soft drinks like Coca-Cola has been linked to various health concerns, including weight gain, an increased risk of type 2 diabetes, and dental issues. The high sugar content leads to rapid spikes in blood sugar levels, and over time, this can contribute to insulin resistance. The liquid form of sugar also makes it particularly easy to consume large quantities quickly without feeling full, leading to an over-consumption of calories without realizing it. Understanding the calories in a 33ml can of Coke—or rather, a 330ml can—is the first step toward making more informed dietary choices.
Making Healthier Beverage Choices
- Switch to Zero-Calorie Options: As mentioned, Diet Coke and Coke Zero offer the familiar taste without the calories.
- Opt for Water: Plain water is the best choice for hydration and has zero calories and zero sugar.
- Explore Flavoured Water: Infusing water with fruits like lemon, cucumber, or berries can add flavour without calories.
- Try Unsweetened Tea or Coffee: These are other low-calorie alternatives to sugary sodas.

Conclusion
To definitively answer the question, there are around 139 calories in a standard 330ml can of Coke. The '33ml can' is a typo that leads to confusion, as this is not a standard size. The vast majority of these calories come from the drink's significant sugar content.
