To enable appropriate nutritional supplementation a correct estimation of resting energy expenditure (REE) is needed. It is, however, unclear whether the volume of ascites should be included or not in the calculations of the REE. Material and methods In 19 patients with cirrhosis and ascites, measurements of REE by indirect calorimetry were performed before paracentesis, after paracentesis, and four weeks after paracentesis. Moreover, handgrip strength (HGS), dual X-ray absorptiometry (DXA), and biochemistry were assessed. Results Calculated and measured REE differed more than 10{\%} in 63{\%} of the patients at baseline. By including the weight of ascites in the calculation of REE, the REE was overestimated by 283 (-602-1381) kJ/day (p = 0.69). By subtracting the weight of ascites in the calculation of REE, it was underestimated by -379 (-1915 - 219) kJ/day, (p  = 0.06). Patients in whom measured REE decreased after paracentesis had higher middle arterial pressure (MAP) (p = 0.02) and p-sodium (p = 0.02) at baseline. Low HGS (M: <30 kg; W < 20 kg) was evident in 68{\%} of the patients. T-scores revealed osteopenia and osteoporosis in 58{\%} and 16{\%}, respectively.
