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 .
Psyllium decreased serum glucose and glycosylated hemoglobin significantly in diabetic outpatients.
Psyllium is a bulk-forming laxative and is high in both fiber and mucilage . The beneficial effect of dietary fiber in the management of type II diabetes , has not been totally demonstrated . The purpose of this study was to determine the plasma-lowering effects of 5.1 g b.i.d . of psyllium husk fiber , as an adjunct to dietary and drug therapy on lipid and glucose levels , in patients with type II diabetes . Patients were r and omly selected from an outpatient clinic of primary care to participate in a double-blind placebo-controlled study in which Plantago ovata Forsk . , or placebo was given in combination with their anti-diabetic drugs .  Forty-nine subjects were included in the study that were given diet counseling before the study and then followed for 8 weeks in the treatment period . Fasting plasma glucose ( FBS ) was measured every 2 weeks , and total plasma cholesterol ( TC ) , LDL-cholesterol ( LDL-C ) , HDL-cholesterol ( HDL-C ) , triglyceride ( TG ) , and insulin levels were measured every 4 weeks . Glycosylated hemoglobin ( HbA1c ) was also measured at the beginning and ending of the study . The test products ( psyllium or placebo ) were supplied to subjects in identically labeled foil packets containing a 5.1 g dose of product , to consume two doses per day , half an hour before breakfast and dinner . Both products were well tolerated , with no serious adverse events related to treatment was reported in either . Better gastric tolerance to metformin was recorded in the psyllium group . FBS , and HbA1c , showed a significant reduction ( p<0.05 ) , whereas HDL-C increased significantly ( p<0.05 ) following psyllium treatment . LDL/HDL ratio was significantly decreased ( p<0.05 ) . Our results show that 5.1 g b.i.d . of psyllium for persons with type II diabetes is safe , well tolerated , and improves glycemic control
