Empty calorie

    Empty calories, in casual dietary terminology, are a measure of the digestible energy present in high-energy foods with little nutritional value, typically processed carbohydrates and ethanol (alcohol), and to some extent fats. Also known as a discretionary calorie, an “empty calorie” has the same energy content as any other calorie but lacks many accompanying nutrients such as vitamins, dietary minerals, antioxidants, amino acids, or dietary fiber.
