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 .
The therapeutic effect of fiber in treating obesity.
This study provides preliminary data on the influence of ingestion of 15 g of dietary fiber daily for 4 weeks on weight change and serum iron concentrations in obese children . During two consecutive 4-week periods , subjects received either fiber/placebo supplements or placebo/fiber supplements . Initially , and after the fourth and eighth weeks , height , weight , and serum iron concentration were obtained . Diet records were maintained throughout the study . No significant differences ( p less than or equal to 0.05 ) were found in weight change , energy , iron , and crude fiber intakes and serum iron concentrations of the subjects between periods of fiber and placebo supplementation . However , mean weight loss of subjects ( 336 g ) was greater during fiber ingestion than during placebo ingestion ( 33 g ) . Due to the small sample size and the subjects ' poor compliance , further studies are needed , with a larger sample size , to determine the effectiveness of different fibers in the treatment of obesity
Moreover , there was nonlinear association between duration of psyllium consumption , BMI and WC .
