What term is used for calories contained in food that have little or no nutritional value?

The term "empty calories" refers specifically to calories in food that provide energy but lack essential nutrients such as vitamins, minerals, fiber, and other beneficial components. Foods that are considered to have empty calories are often high in added sugars or unhealthy fats. Common examples include sugary drinks, candies, and many processed snacks, where the calorie content is high, but the nutritional benefits are minimal.

Understanding this concept is important because consistently consuming empty calories can lead to health issues such as obesity, nutrient deficiencies, and metabolic disorders, despite the high caloric intake. This term emphasizes the distinction between foods that contribute to overall nutritional needs and those that do not.
