Abstract
In order to obtain calorie expenditure with good accuracy, the device is provided with a basal metabolic state specifying element (142) which specifies the subject'"'"'s basal metabolic state from his body temperature; a correlation storing element (151) which stores respective regression formulas showing the correlation between the pulse rate and the calorie expenditure when the subject is at rest or active; a correlation correcting element (152) which correcting the stored regression formulas using the basal metabolic state; a body motion determining element (104) which determines whether or not the subject is at rest; and a regression formula selecting element (153) which selects the regression formula which should be used in accordance with the results of this determination. The subject'"'"'s pulse rate is applied in the selected regression formula, and the calorie expenditure corresponding to this pulse rate is calculated by calorie expenditure calculator (162).
