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 .
Soluble fibre (Plantago ovata husk) reduces plasma low-density lipoprotein (LDL) cholesterol, triglycerides, insulin, oxidised LDL and systolic blood pressure in hypercholesterolaemic patients: A randomised trial.
UNLABELLED The objective was to evaluate whether the soluble fibre Plantago ovata (Po)-husk improves cardiovascular disease ( CVD ) risk biomarkers including low-density lipoprotein cholesterol ( LDL-C ) . METHODS In a multi-centred , double-blind , placebo-controlled , parallel , r and omised trial conducted in primary care-clinics in Spain , France and Holl and , mild-moderate hypercholesterolaemic patients ( age range : 43 - 67 years ) received 14 g/d of Po-husk ( n=126 ) or placebo ( microcrystalline-cellulose 14 g/d ; n=128 ) in a low saturated fat diet for 8 weeks . Subsequently , if LDL-C remained > or = 3.35 mmol/L [ 130 mg/dL ] , participants proceeded with the fibre plus simvastatin ( 20mg/d ) for further 8 weeks . Lipid profile , blood pressure ( BP ) , insulin , oxidised LDL and some gene polymorphisms involved in CVD risk were measured . RESULTS Relative to placebo , Po-husk reduced plasma LDL-C by -6 % ( P<0.0002 ) , total cholesterol ( TC ) by -6 % , triglycerides ( TG ) by -21.6 % , apolipoprotein ( Apo ) B-100 by -6.7 % , oxidised LDL by a mean of -6.82 U/L ( 95%CI : 3.15 - 10.48 ) , insulin by -4.68 pmol/L ( 95%CI : 0.68 - 8.67 ) and systolic BP by -4.0 mm Hg ( 95%CI ; 1.2 - 6.7 ) ( P<0.05 ) . The TG-lowering effect in the Po-husk group was magnified by variants in plasminogen-activator-inhibitor ( PAI-1 ; rs1799768 ) and fatty acid-binding protein ( FABP-2 ; rs1799883 ) genes . At 16 weeks , the intra-group action of simvastatin ( 20mg/d ) added to Po-husk or placebo was a similar LDL-C reduction . CONCLUSIONS Po-husk , apart from lowering LDL-C , also reduced TG , TG related to certain gene variants , TC , Apo B-100 , oxLDL , insulin-resistance and systolic BP in mild-moderate hypercholesterolaemic individuals . Thus , the target patients to receive Po-husk would be those who present a cluster of various CVD risk factors , such as metabolic syndrome
