A note on the percentage loss of calories as waste on ordinary mixed diets

Abstract

It is customary to state the energy needs of an individual, a family or some larger group in terms either of net or gross calories. If the original estimate has been made from a study of the actual or net intake, what extra percentage would have to be added to this net basal figure to permit the need to be stated in gross calories? A similar problem arises in the conversion of gross to net requirements.
