Resting metabolic rate (RMR) accounts for about two thirds of total energy expenditure. The widely used Harris-Benedict equations systematically overestimate RMR. This study assessed overall reliability and validity of a handheld indirect calorimeter, BodyGem, on a sample of women. Thirty healthy nurses participated in this study with an age of 41.9 ± 9.0 years old and a body mass index of 24.0 ± 2.8 kg/m 2. The Deltatrac Metabolic Monitor was used as the criterion method to validate BodyGem. Reliability was estimated by repeated measures of BodyGem to test internal consistency and stability. Analysis indicated that measurements of Deltatrac and BodyGem are well correlated (r = 0.76, P <0.001). The correlation coefficients of two BodyGem RMR measurements were of large statistical significance (r = 0.96, P
