Why Coca-Cola Zero Leaves You Feeling Hungry While Light Drinks Never Satisfy If you’re a die-hard fan of Coca-Cola Zero Sugar but often find yourself feeling hungry shortly after drinking it—or craving more despite the “zero-calorie” label—you’re not alone. This unusual phenomenon raises an intriguing question: Why does Coca-Cola Zero seem to trigger hunger while lighter, non-zero sodas often leave you feeling full longer? Let’s dive into the science behind this sensation, exploring how ingredients, metabolism, and brain signals contribute to that persistent craving. ### The Zero-Calorie Blueprint: What’s Inside Coca-Cola Zero? Coca-Cola Zero Sugar replaces sugar with artificial sweeteners like aspartame and acesulfame potassium. While it delivers zero calories and no sugar, the liquid contains little other than these sweeteners and small amounts of preservatives and flavor enhancers. Unlike regular Coke, which contains hundreds of calories from sugar and carbs, Zero Sugar has negligible food energy—but its effects on hunger and satiety are far from inert.
