Values are mean ± SEM with baseline as a covariate. Mean change from baseline. P values are within group differences compared to baseline. Different letters in superscript represent significant differences between groups p < 0.05. CHO (carbohydrate), CTR (control), PGX (PolyGlycopleX), PSY (psyllium). Dietary intake data missing at baseline or 3 months (n = 14). 4.184 kJ = 1 kCal
