Anthropometric variables, energy expenditure, and respiratory quotient in the MP and HP groups1
| MP (n = 18) | HP (n = 20) | P value | |
|---|---|---|---|
| Sex, f/m | 9/9 | 13/7 | |

| BMI, kg/m2 | 29.0 ± 3.8 | 28.9 ± 4.0 | 0.942 |
| Fat-free mass, kg | 52.5 ± 10.9 | 50.8 ± 11.3 | 0.553 |
| Fat mass, kg | 33.9 ± 7.7 | 34.8 ± 8.8 | 0.740 |
| Body fat, % | 39.3 ± 7.4 | 40.7 ± 7.7 | 0.593 |
| Calculated EI, MJ/d | 9.4 ± 1.7 | 9.3 ± 1.6 | 0.573 |
| EB, MJ/d | 0.2 ± 0.9 | −0.5 ± 0.9 | 0.015 |
| RQ | 0.84 ± 0.02 | 0.82 ± 0.02 | 0.004 |
| Activity, CPM | 133.3 ± 34.1 | 155.0 ± 36.6 | 0.087 |
1Values are means ± SDs. Differences between groups were assessed by means of Mann-Whitney U tests. CPM, counts-per-minute; EB, energy balance; EI, energy intake; HP, high protein; MP, moderate protein; RQ, respiratory quotient.
