Values are presented as means (SD), = 8. Respiratory Exchange Ratio measurements represent averages over fasting (20 min), postprandial (0 to 25 min and 25 to 55 min), and exercise (30 min) time periods.
†  Significant interaction of time and test meal between fasting and postprandial 25 min measurements.
Ч Significant interaction of time and test meal between postprandial 25 min and postprandial 55 min measurements.
§ Significant interaction of time and test meal between postprandial 55 min and exercise measurements.
