Abstract: In order to assess the constituent ratios of energy expenditure in human, the deductive process of establishing a mathematical
model for assessing the constituent ratios of the three major nutrients in energy expenditure in human was described in this paper. Total
oxygen consumption, total carbon dioxide output and total nitrogen (urine nitrogen + skin nitrogen) excretion are related to the oxidation
of the three major nutrients and the bustion values of the three nutrients are already known. Based on these
measurable and known parameters, the mathematical model established by the authors will help understand the characteristics of the
tested individual’s energy expenditure.
Key words: energy expenditure; indirect calorimetry; bustion value; energetic nutrients; constituent ratio; mathematical
