Measurement of Energy Expenditure by Body-worn Heat-flow Sensors

Neil Szuminsky1, John Dykstra1 and Ed Melanson2,    1MetaLogics Corporation, Minneapolis, Minnesota, USA,    2University of Colorado Anschutz Medical Campus, Denver, Colorado, USA

Most body-worn devices that report calories estimate energy expenditure by measuring one or more surrogate parameters, most commonly some form of motion. These devices are susceptible to significant inaccuracies in the estimation of caloric expenditure. Accurate measurement of energy expenditure requires either the measurement of oxygen consumption (indirect calorimetry) or heat production (direct calorimetry), but neither has been used successfully in a body-worn sensor that can be used in ...
