Calories themselves are measurement of energy, so 100 Calories of anything is 100 Calories. “Empty” calories just refers to something having little to no nutrient value. I think your question has more to do with why some foods feel more filling than others though, and the answer to that is fiber, fats, and protein content. Some foods help us feel more satiated because they bulk up with water in our bellies, or we take longer to eat them so our brains have time to let us know we’re full, or they take longer to digest so we do they another hunger signal as quickly.
