| Epididymal fat pads (g) | 4.9 ± 0.9 | 5.0 ± 0.8 | 5.2 ± 0.9 | 5.2 ± 0.7 |
| Caloric intake (kcal/day) | 86.6 ± 9.5 | 83.4 ± 9.6 | 80.5 ± 9.2 | 79.6 ± 8.8 |
| Caloric expenditure (kcal/kg bw0.75/day) | 104 ± 11 | 108 ± 12 | 111 ± 11 | 111 ± 12 |
| Carbohydrate oxidation (kcal/kg bw0.75/day) | 4.4 ± 0.6 c | 5.5 ± 0.6 a,b | 6.1 ± 0.7 a | 5.3 ± 0.6 b |

Values are means ± standard deviation. Px rats were fed a high fat diet supplemented with (1) 0.5% water extract of Gastrodia elata Blume (GEB-L); (2) 2% water extract of Gastrodia elata Blume (GEB-H); (3) 2% dextrin (Px-control); or (4) rosiglitazone (20 mg/kg body weight; positive control) for eight weeks. a,b,c Means on the same row with different superscripts were significantly different at p < 0.05.
