Low-calorie sweeteners, also known as artificial sweeteners or sugar substitutes, are substances used to sweeten foods and beverages while providing minimal or no calories. They are commonly used as alternatives to sugar for individuals looking to reduce their calorie intake, manage blood sugar levels, or control their weight. Here are some common low-calorie sweeteners:

Aspartame: Aspartame is one of the most widely used low-calorie sweeteners and is found in many diet sodas, sugar-free gum, and other low-calorie or sugar-free products. It is about 200 times sweeter than sucrose (table sugar).

Sucralose: Sucralose is a no-calorie artificial sweetener derived from sugar. It is about 600 times sweeter than sucrose and is commonly found in products like diet soda, baked goods, and tabletop sweeteners.
