Coke Zero contains zero calories, so it won’t directly cause weight gain, but some studies suggest artificial sweeteners may influence appetite and cravings.
Coke Zero has become a popular choice for those looking to cut calories without giving up soda. But does it actually help with weight loss, or could it contribute to weight gain? Let’s examine the science behind this zero-calorie beverage.
Nutritional Profile of Coke Zero
Coke Zero contains:
- 0 calories
- 0 grams of sugar
- 0 grams of fat
- Artificial sweeteners (aspartame and acesulfame potassium)
- Caffeine (34mg per 12oz can)
- Phosphoric acid
Compared to regular Coca-Cola which contains 140 calories and 39g sugar per 12oz can, Coke Zero appears to be the better choice for weight management. However, nutrition isn’t always that simple.
How Coke Zero Might Affect Your Weight
The Artificial Sweetener Debate
Research on artificial sweeteners like those in Coke Zero shows mixed results:
| Study Findings | Potential Impact |
|---|---|
| May increase ghrelin (hunger hormone) | Could lead to increased food intake |
| May alter gut microbiome | Could affect metabolism |
| May trigger sugar cravings | Could lead to less healthy food choices |
A Harvard Health study found that carbonated drinks (even without calories) increased ghrelin levels more than flat beverages.
The Carbonation Factor
Research suggests carbonation itself might influence weight:
- Animal studies show carbonated beverages led to increased food intake
- Carbonation may stimulate hunger hormones
- The mechanism isn’t fully understood but appears independent of sweeteners

The Bottom Line
Coke Zero itself doesn’t contain calories that would directly cause weight gain. However, the artificial sweeteners and carbonation might indirectly affect your eating habits and metabolism in ways that could lead to weight gain for some people. The effect varies by individual.
As with many nutrition questions, moderation is key. An occasional Coke Zero likely won’t derail your weight goals, but regular consumption might have unintended consequences. Pay attention to how your body responds and adjust accordingly.
