A calculated measurement of the difference in the weight of food (material, usually of plant or animal origin, that contains essential nutrients such as carbohydrates, fats, proteins, vitamins, and/or minerals and that is ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life) taken in for utilization by the body between two points in time or two conditions, expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity. Weight is the vertical force experienced by a mass as a result of gravitation.

The term "absolute change" refers to the subtraction of one value from another, as opposed to a dissimilarity of two values expressed as a ratio or as a percentage. In this context it is not intended to necessarily imply the difference expressed as an absolute value |n|, that is, the numeric value of the difference without regard to its sign.
