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 .
Can alginate-based preloads increase weight loss beyond calorie restriction? A pilot study in obese individuals
This r and omized , controlled , 2-week intervention study in 24 obese subjects tested the effect on body weight loss and gastrointestinal tolerance of consuming low viscous alginate fibre-based preloads of 3 % concentration ( 500 ml volume ) three times a day as an adjuvant to a calorie-restricted diet . The pilot study showed that intake of the alginate preloads was moderately acceptable to the majority of subjects but did not produce additional body weight loss beyond calorie restriction ( -1.42 ± 0.38 kg ) ( n=12 ) compared to control group ( -1.56 ± 0.21 kg ) ( n=8 ) . These results do not support that alginate supplementation enhance the weight loss effects of a hypo-caloric diet , but a sufficiently powered long-term study is needed to explore whether alginate could be an aid for improving weight loss during caloric-restriction
