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.
Š§ Significant interaction of time and test meal between postprandial 25 min and postprandial 55 min measurements.
