Table 2 Comparisons of mean (± SE) baseline and postprandial metabolic rate (kcal/min) expressed per kg of fat free mass (ffm) among groups

From: Changes in energy expenditure associated with ingestion of high protein, high fat versus high protein, low fat meals among underweight, normal weight, and overweight females

  1. * 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.
