Values are means ± SD. Body fat and waist circumference (n = 35 normal weight). Insulin and homeostatic model assessment for insulin resistance (HOMA-IR; n = 19 normal weight; n = 11 obese). %Female compared using χ2 test. All other variables compared using one-way analysis of variance or Kruskal–Wallis one-way analysis of variance on ranks (normality, Shapiro–Wilk; equal variance, Brown–Forsythe).
