Zero-sugar, zero-calorie beverages—often marketed as the ultimate guilt-free refreshment—have exploded in popularity among dieters and health-conscious consumers. Whether it’s a fizzy cola, a fruit-flavored sparkling water, or a trendy energy drink, these beverages promise all the flavor with none of the calories, sugar, or regret. But can you really drink them as much as you want when you’re trying to lose weight? The answer, as with so many things in nutrition, is more nuanced than marketing slogans suggest.

Zero-calorie drinks typically contain non-nutritive sweeteners (NNS), also known as artificial or high-intensity sweeteners. Common examples include aspartame, sucralose, stevia, and acesulfame potassium. The scientific community has spent decades investigating their safety and impact on weight and metabolism.
