  1. Parameters measured in five overweight dogs by indirect calorimetry (IC) and the oral 13C-bicarbonate technique (o13CBT), two times at the start (n = 10) and two times at the end (n = 10) of a body weight (BW) reduction program. Results are shown as LS-means with the 95% confidence intervals (CI). R O2 = O2 consumption, R CO2 = CO2 production, RF = recovery factor, RQ = respiratory quotient, HR = heart rate, bpm = beats per minute, EE = energy expenditure, FFM = fat free mass, NS = not significant.
