BMR was derived using three methods: Harris-Benedict equation, Bioelectrical Impedance Analysis and Indirect Calorimetry.</p><p style="text-align: justify;"><strong>Results.</strong> A total of 153 subjects were included in the study. Eighty subjects (52%) have pre-diabetes while 73 subjects (48%) were diagnosed with T2DM. The mean BMR measured using IC is 1299±252 kcal/day while estimated mean BMR predicted using HB equation and BIA were 1628±251 kcal/day and 1635+260 kcal/day, respectively. Compared to measurement by IC, HBE and BIA significantly overestimated the mean BMR by 329 and 336 kcal/day, respectively (<em>p value</em>=<0.0001). IC measured BMR showed strong positive correlation with weight and moderate positive correlation with height. Multiple stepwise regression analysis yielded the BMR prediction equation: BMR (kcal/day)=-780.806 + (11.108 x weight in kg) + (7.164 x height in cm).</p><p style="text-align: justify;"><strong>Conclusion.</strong> Among obese Filipinos with T2DM or prediabetes, HB equation and BIA tend to overestimate the BMR measured using IC.</p>}, number={2}, journal={Journal of the ASEAN Federation of Endocrine Societies}, author={Luy, Sybil Claudine and Dampil, Oliver Allan}, year={2018}, month={Sep.}, pages={152} }
