Continuing the trend of stating the obvious, it is absolutely possible to load food with too much sugar or fat that offers practically no marginal nutritional value. I say marginal because of course to a starving person the calories brought in by sugar are valuable, but probably not to a person who is generally able to get their calories from a wide range of sources and in general wants to control their caloric intake.

Empty calories is not a moral judgment. It is a statement of fact.
