Comparison of body composition and resting energy expenditure between baseline and after weight loss (n = 110 females, study population 3 without organ-tissue analysis).

	Before weight loss	After weight loss
Age, years	36.2 ± 9.7
Weight, kg	107.9 ± 21.8	93.9 ± 17.1***
BMI, kg/m2	38.0 ± 7.0	33.0 ± 4.9***
FFM, kg	54.3 ± 7.4	52.8 ± 6.1**
FM, kg	53.6 ± 16.6	41.1 ± 13.3***
FM, %	48.8 ± 6.3	42.8 ± 7.1***
REE, MJ/day	7.46 ± 1.06	6.79 ± 0.84***
REEmeasured-predicted according to FFM and FM regression before weight loss, MJ/day	0.01 ± 0.64	−0.23 ± 0.51***
REEmeasured-predicted according to %FM-specific FFM-regressions, MJ/day†	− 1.23 ± 0.65	−1.28 ± 0.58
