The mean values and mean changes and 95% confidence interval (CI) with lower and upper limits are presented for anthropometric parameters at inclusion (baseline) (n = 30), 12 weeks after diet intervention (n = 30), and 16 weeks after the end of diet intervention (week 28) (n = 23). Linear mixed model. Comparisons were made between baseline and week 12 and week 28. P < 0.05 was considered statistically significant.
