Aspartame is indeed several times sweeter than table sugar, meaning that a smaller amount of aspartame is required to achieve the same level of sweetness in food items compared to sugar. Since aspartame is used in smaller quantities due to its high sweetness, the overall calorie content of the food item is reduced. This is because aspartame provides fewer calories per unit weight compared to sugar. Upon ingestion, aspartame is metabolized in the body into compounds that do not yield calories. Therefore, even though it is sweet, it does not contribute significantly to the calorie intake, making it suitable for use in low-calorie food products
