* No difference among groups at baseline, but a significant (p = 0.0001) effect of BMI classification across all postprandial times and treatments. However, the difference in energy expenditure between the overweight and normal weight groups was not significant, but the energy expenditure of underweight group was still significantly less than the other two groups across all times and treatments.
