Foods heavy in fats and sugars that provide more calories than nutrients are referred to as empty calories. On the religious landscape the writer of Hebrews cautioned against spiritually empty calories found in the ceremonial foods of the Aaronic priesthood and sacrifices. “Do not be carried away by all kinds of strange teachings. It is good for our hearts to be strengthened by grace, not by ceremonial foods, which are of no value to those who eat them. We have an altar from which those who minister at the tabernacle have no right to eat” (Heb 13:9-10 NIV).
