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 .
Relationship of satiety to postprandial glycaemic, insulin and cholecystokinin responses
The effect of plasma glucose on satiety and the capacity of carbohydrates to stimulate cholecystokinin ( CCK ) remain unclear . The aim of this study was to test the hypothesis that the magnitude of the postpr and ial plasma glucose and insulin response is inversely related to the CCK response and to subjective satiety .  Seven healthy , male volunteers consumed equal carbohydrate portions ( 0.5 g/kg body weight ) of six test meals ( Rice Bubbles , Sustain , Vita-Brits , All-Bran , porridge and white bread ) in r and om order after an overnight fast . An egg and bacon meal was consumed as a non-carbohydrate control providing 0.5 g protein/kg body weight . Serum CCK , plasma glucose and insulin and subjective satiety ( measured by a rating scale ) were assessed over 3 h and quantified using the glycaemic index ( GI ) , insulin index ( II ) , the peak satiety score and area under the incremental curve ( AUC ) . The observed GIs ( mean + /- SE ) ranged from 42.5 + /- 2.6 for All-Bran to 116.2 + /- 11.4 for Rice Bubbles , using white bread as the reference food ( GI = 100 ) . Peak satiety scores varied eightfold from 0.21 + /- 0.4 for Sustain to 1.64 + /- 0.4 for All-Bran . Significant inverse relationships were observed between the peak satiety score and both the glycaemic and insulin index of the seven meals ( r = -0.916 , p less than 0.001 and r = -0.926 , p less than 0.001 ) . A direct relationship was observed between satiety ( AUC ) and the CCK response ( AUC ) ( r = 0.73 p less than 0.01 ) . The results suggest that glycaemic and insulin responses to carbohydrate foods are inversely proportional to the CCK response and satiety
