Table 2. Food intake, substrate oxidation and energy expenditure in in rats fed with a CD and supplemented with GSPE or vehicle.
| CD | CD+GSPE | |
|---|---|---|
| Energy intake (kJ day−1 per animal) | 1197.32±31.1 | 1105.83±45.4a |
| Respiratory quotient | 0.89±0.1 | 0.88±0.1 |
| Energy expenditure (kcal day−1 kg−1 0.75) | 68.28±2.2 | 66.73±5.3 |
| Carbohydrate oxidation (kJ min−1 kg−1 0.75) | 127.39±17.9 | 152.59±34.9 |
| Fat oxidation (kJ min−1 kg−1 0.75) | 51.76±11.4 | 61.33±9.5 |
Abbreviations: CD, cafeteria diet; GSPE, grape-seed proanthocyanidins extract; STD, standard chow diet.
After 10 weeks rats fed a CD received oral treatment of GSPE (25 mg per kg of body wt) (CD-GSPE group) or vehicle (CD group) for 21 days. Values are mean ±s.e.m. of seven samples from each group.
