Note: ^abValues in a row with the same superscript did not differ significantly between the HPHF meal and the HPLF meal within a BMI group.

*Values in a row did not differ significantly among BMI groups following consumption of the HPHF meal.

°Values in a row did not differ significantly among BMI groups following consumption of the HPLF meal.

^#EE/I (%) represents the average energy expenditure over 210 minutes divided by 440 kcal intake × 100 (9)
