Actually, it is different. But they claim they know the difference, yet they continue to make the wrong choice. Empty calories are carbs, usually GLUTEN. Eating empty calories causes nutrient deficiency, which is a major hunger driver: body cries out for "food" and the retarded fatfucks keep giving it carbs, sugars, gluten. Repeat cycle. Here's an example in action: ranchers give cattle food rich with vitamins while they are maturing. As slaughter day approaches, rancher removes the vitamins. Cattle eat like crazy, trying to get the missing vitamins. They gain weight rapidly on the empty calories, just like their human fatfucks, right before getting slaughtered.
