Moreover , there was nonlinear association between duration of psyllium consumption , BMI and WC .
Conclusion : Psyllium supplementation does not reduce body weight , BMI , and WC significantly
Abstract Background : Previous studies reported inconsistent findings regarding the effects of psyllium supplementation on  obesity measures .
This systematic review and meta- analysis was performed to summarize data from available r and omized clinical trials ( RCTs ) on the effect of psyllium supplementation on  body weight , body mass index ( BMI ) , and waist circumference ( WC ) in adults .
Effects of psyllium vs. placebo on constipation, weight, glycemia, and lipids: A randomized trial in patients with type 2 diabetes and chronic constipation.
OBJECTIVE To compare the effects of baked psyllium supplementation versus those who received a placebo on constipation symptoms , body weight , glycemic and lipids control in patients with type 2 diabetes ( T2D ) and chronic constipation . METHODS In a single-blinded , r and omized controlled trial , 51 patients with T2D and chronic constipation with body mass index ( BMI ) 20 - 47 kg/m2 received either 10 g of psyllium pre-mixed in cookies twice per day or placebo cookies for 12 weeks . Constipation symptoms , body mass index ( BMI ) , fasting plasma glucose ( FPG ) , glycosylated hemoglobin ( HbA1c ) , and lipid profile were determined at the beginning and end of 4 , 8 , and 12-week period . Constipation was evaluated with a stool diary ( ROME III ) . RESULTS The psyllium group showed improvement in constipation symptoms , body weight , glucose and lipid values compared with the baseline and the placebo group . Body weight and FPG decreased from baseline in the psyllium group ( P < 0.001 and P = 0.056 , respectively ) . The differences ( 95 % CI ) of absolute change of body weight ( -2.0 ( -3.0 , -1.0 ) kg ; P < 0.001 ) , FPG ( -13.6 ( -24.3 , -2.9 ) mg/dl ; P = .040 ) , and HbA1c ( -1.7 ( -2.9 , -0.5 ) ) ; P = 0.002 ) between the groups were statistically significant . Cholesterol ( -21.5 ( -25.6 , -14.4 ) ; P < 0.001 ) , triglycerides ( -20.0 ( -32.3 , -7.7 ) ; P = 0.021 ) and constipation symptoms ( 1.5 ( 0.4 , 2.3 ) ; P < 0.001 ) decreased in the psyllium group . The compliance was good and no adverse effects were observed . CONCLUSION In patients with T2D and chronic constipation , psyllium supplementation decreased constipation symptoms , body weight , glycemic , cholesterol , and increased HDLC levels
Moreover , there was nonlinear association between duration of psyllium consumption , BMI and WC .
