Data are means ± SEM. n = 38: 18 men and 20 women; 14 normal-weight subjects, 14 overweight subjects (BMI 25 to <30 kg/m²), and 10 obese subjects (BMI ≥30 kg/m²). Differences between men and women were not significant.

^*For comparisons with body fat quartile 4 and obesity, respectively.

^†P = 0.015 and 0.002 for comparison with body fat quartiles 2 and 3, respectively.

^‡P = 0.03 for comparison with overweight.
