RESULTS The present study indicated that the efficacy of various fiber supplements on losing weight is variable .
Several mechanisms related to physicochemical properties of fibers such as solubility , fermentability and viscosity rates can be involved in their anti-obesity effects .
Dextrin , Mannan ( gum Arabic ) and pectin-rich fiber ( lupin kernel ) with no dietary interventions indicated a reduction in body weight and energy intake , while from clinical point of view , their effects were not considerable .
Overall , findings indicated that the efficacy of fiber supplements on obesity management is dependent on their contents and physicochemical properties .
It seems that fiber supplements with no weight-loss interventions did not have considerable antiobesity effects .
BACKGROUND Previous trials have reported beneficial effects of isolated and complex fiber supplements in obesity treatment .
However , recommending fiber supplements in obese subjects remains controversial .
To the best of our knowledge , no systematic review has up date d the data on the effects of fiber supplements on obesity since 2010 and the need exists for a systematic review on this topic .
Accordingly , a systematic review was undertaken to summarize the efficacy of different types of fiber supplements as a complementary treatment for weight management .
The effects of 12-week psyllium fibre supplementation or healthy diet on blood pressure and arterial stiffness in overweight and obese individuals.
Endothelial dysfunction and increased arterial stiffness occur early in the pathogenesis of the metabolic syndrome and they are both powerful independent predictors of cardiovascular risk . A high-fibre diet has been correlated with lower BMI and a lower incidence of hyperlipidaemia , CVD , hypertension and diabetes . The present r and omised , parallel- design study compared the effects of fibre intake from a healthy diet v. fibre supplement diets on blood pressure ( BP ) and vascular function over 12 weeks . Overweight and obese adults were r and omised to one of three groups : control ( with placebo ) , fibre supplement ( FIB ) or healthy eating group with placebo ( HLT ) . Systolic blood pressure ( SBP ) was lower in the FIB group compared with the control group at week 6 , but not at week 12 . However , SBP was lower in the HLT group compared with control group at week 12 . At week 6 , the FIB group presented lower diastolic blood pressure and augmentation index compared with the control group , but this result did not persist to the end of the study . The present study did not show any improvements in BP or vascular function in overweight and obese individuals with psyllium fibre supplementation over 12 weeks of intervention . However , a healthy diet provided the greatest improvements in BP in overweight and obese subjects . Further research with hypertensive individuals is necessary to eluci date whether increased fibre consumption in the form of psyllium supplementation may provide a safe and acceptable means to reduce BP , vascular function and the risk of developing CVD
