5% time = onset of TEF that exceeds 5% increase in RMR; 10% time = onset of TEF that exceeds 10% increase in RMR; p = between sexes t-test p value; No Increase = no increase in TEF within 30-min was seen that exceeded 5% or 10% of RMR.

CHO = high carbohydrate; PRO = high protein.

a, b, c, d, e, f represent t-test comparisons between CHO and PRO:

a, p = 0.14; b, p = 0.46; c, p = 0.77; d, p = 0.20; e, p = 0.90; f, p = 0.36.
