Why does sugar-free jello contain fewer calories than regular jello?

Sugar-free Jell-O contains fewer calories than regular Jell-O because it uses artificial sweeteners instead of sugar.

Here's a breakdown:

* Regular Jell-O: Contains sugar, which provides calories. Sugar is a carbohydrate and a primary source of energy for our bodies.

* Sugar-free Jell-O: Uses artificial sweeteners like sucralose or aspartame. These sweeteners are much sweeter than sugar but have very few calories. They trick your taste buds into perceiving sweetness without providing significant energy.

In simple terms:

* Sugar is calorie-dense.

* Artificial sweeteners are calorie-light.

Therefore, by substituting sugar with artificial sweeteners, sugar-free Jell-O significantly reduces its calorie content.
