TANSTAAFL: A rather cumbersome and usually hard to remember acronym for the expression "There ain't no such thing as a free lunch. This is a favorite saving of many economists because it highlights, albeit in a grammatically questionable manner, the fundamental problem of scarcity. The phrase serves to emphasize that seemingly "free" lunches are not really free. While they might be free to the customer, someone must pay, that is, incur an opportunity cost of foregone production. The lunch eaten by one person cannot be eaten by another.

A change in real production is comparable to a change in quantity supplied. A change in real production for short-run aggregate supply means real production changes with a movement along a given short-run aggregate supply curve. However, the term "change in real production" is also used for movements along a given long-run aggregate supply curve, even though real production does not actually change in the long run.
