                                Fact: All food, except plain water, contains calories, the unit of energy our bodies need to function. This debunks the common misconception and addresses the popular question, 'Is there a snack with 0 calories?'. The concept, while appealing, is rooted in a misunderstanding of metabolism and food science.
