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 .
Effects of a 3-month supplementation with a novel soluble highly viscous polysaccharide on anthropometry and blood lipids in nondieting overweight or obese adults.
BACKGROUND High viscosity fibre is known to exert many beneficial effects on appetite and metabolism . It could potentially help in weight management , in dieting or nondieting individuals . The present study investigated the effects of the daily intake of a novel high viscosity polysaccharide ( HVP ) over 3 months in nondieting obese or overweight men and women . METHODS The study comprised a double-blind , r and omised controlled clinical trial . Participants ingested 5 - 15 g per day of either HVP ( n = 29 , experimental group ) or inulin ( n = 30 , control group ) for 15 weeks . Changes in anthropometry ( weight , waist and hip circumferences ) , blood lipids and glucose tolerance were studied from the beginning to the end of administration . Compliance and tolerance were examined . RESULTS Differences appeared between HVP and inulin supplementation in female participants only .  Mean ( SD ) decreases in body weight [ 1.6 ( 3.2 ) kg ; approximately 2 % of initial weight ] and hip circumference [ 2.8 ( 3.6 ) cm ] occurred in women of the HVP group but not in controls ( Time × Group interactions , P ≤ 0.002 ) . Total , high-density lipoprotein and low-density lipoprotein-cholesterol were lower at the end of supplementation in the women of the HVP group compared to controls ( P ≤ 0.021 ) . No effect appeared in waist circumference and triacylglycerol . No difference was noted in the number or severity of the adverse effects reported in both groups . Adverse effects were mild and agreed with commonly reported reactions to intake of dietary fibre . CONCLUSIONS Beneficial although modest effects appeared after several weeks of daily HVP intake in nondieting obese or overweight women . The effects of HVP should be investigated in the context of a weight loss programme
