Abbreviations: BMI, body mass index; HDL, high-density lipoprotein; HOMA, homeostasis model assessment; LDL, low-density lipoprotein.

Statistical analyses: GLM ANCOVA model, where measures of each parameters at baseline, 3 months, and 1 year were the dependent variable; treatment group the independent variable; and baseline BMI, sex, and age were the covariates.
