  1. Data shows mean ± S.D.
  2. Abbreviations: BMI Body mass index, BFP Body fat percentage, SBP Systolic blood pressure, DBP Diastolic blood pressure, WC Waist circumference.
  3. *p stands for the difference between the baseline parameters and the parameters after 3 months analyzed by the paired t-test.
  4. p stands for the difference between the baseline parameters and the parameters after 3 months analyzed by Wilcoxon’s signed rank test.
  5. Difference was considered significant at p < 0.05.
