| BMI (kg/m2) | 26.4 ± 4.0 | 29.5 ± 5.9 | 23.0 ± 1.52 |
| Body fat (%) | 35.4 ± 6.6 | 37.5 ± 6.5 | 25.5 ± 2.02 |
| Fat-free mass (kg) | 44.1 ± 3.8 | 46.7 ± 5.9 | 45.0 ± 4.1 |
| Resting metabolism | |||
| RMR (kcal/d) | 1307 ± 185 | 1367 ± 161 | 1444 ± 156 |
| RQ | 0.85 ± 0.06 | 0.82 ± 0.06 | 0.85 ± 0.03 |
1
All values are means ± SDs. RMR, resting metabolic rate; RQ, respiratory quotient.
2
Significantly different from lactating and nonlactating women, P < 0.05 (unpaired t tests for equal or unequal variances).
