caloriefree

Caloriefree is a marketing label used to describe products or substances claimed to contribute little or no calories to a diet. The term functions as a consumer-facing category rather than a scientific designation, and it often accompanies other claims such as "calorie-free" or "zero calories." In practice, caloriefree products rely on approaches like non-nutritive sweeteners, high water content, or other means to minimize energy per serving.

Regulatory context: In the United States, the Food and Drug Administration specifies that a product can be labeled calorie-free only if its energy content is 5 calories or fewer per reference serving. Similar thresholds exist in other jurisdictions, with variations in how serving sizes are defined. Producers must not mislead by using "caloriefree" claims if energy exceeds a small threshold.

Typical applications include carbonated and still beverages, flavor-enhanced waters, broths, and some snack items marketed as light or diet. Many caloriefree products rely on non-nutritive sweeteners or minimal macronutrient content to achieve low energy values. The term is most common in consumer packaging and online product listings rather than scientific literature.

Critics note that "caloriefree" does not guarantee weight loss and can blur the distinction between energy intake and appetite regulation. Consumers should consider serving size, ingredient lists, and overall daily intake rather than relying on a single label.
