Rating (out of 5): 2

Rebaudioside A is a steviol glycoside found in the leaves of the Stevia rebaudiana plant and is commonly used as a high-intensity, non-nutritive sweetener. Its use in supporting weight loss is primarily justified by its ability to provide sweetness with minimal to no calories, allowing individuals to reduce caloric intake from sugar-sweetened foods and beverages. Several short-term clinical trials have investigated the effects of non-nutritive sweeteners, including Rebaudioside A, on body weight. These studies generally show that substituting caloric sweeteners with non-caloric options may modestly reduce energy intake and support weight loss or maintenance when part of an overall calorie-controlled diet.

However, the evidence is not strong or specific to Rebaudioside A alone, as most research groups various non-nutritive sweeteners together. Some meta-analyses and systematic reviews suggest a small but significant effect on body weight, while others highlight inconsistencies, methodological limitations, and potential compensatory increases in calorie intake from other foods. There is no robust evidence that Rebaudioside A exerts direct biological effects on fat metabolism or appetite regulation beyond its role as a sugar substitute. Thus, while its use is scientifically plausible for supporting weight loss as part of dietary strategies to reduce calorie intake, the strength of evidence is moderate and not conclusive.
