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 .

Satiety effects of a whole-grain fibre composite ingredient: reduced food intake and appetite ratings.
The current study assesses the impact on appetite and food intake of a novel co-processed ingredient containing a viscous fibre and whole-grain high-amylose corn flour , a source of type 1 and type 2 resistant starch ( HAM-RS ) . Ninety adults completed a crossover , placebo-controlled study comparing two doses of the ingredient ( 20 and 30 g ) to a maltodextrin control in a fruit-based smoothie served with breakfast .  Ad libitum food intake was measured over the day and visual analogue scales were used to assess subjective appetite sensations . Subjects consumed 7 % less energy intake at dinner following the 30 g dose ( p = 0.02 ) compared to control . In addition , a trend for lower lunch intake ( 5 % less weight of food ) was observed for the 20 g dose ( p = 0.10 ) . Reductions were also observed for the two meals combined , with 3 % lower energy intake for the 20 g dose ( p = 0.04 ) and 5 % less weight of food consumed for the 30 g dose ( p = 0.04 ) . Lower ratings of hunger were reported at 3 h after breakfast for both doses and also at 2 and 3 h after lunch for the 30 g dose . With ratings combined to compute an overall appetite score , a trend for lower appetite scores at 3 h after breakfast was found for both doses . Consistent with this , significant reductions in AUC hunger and prospect i ve consumption were identified in the 30 g condition . A similar pattern of results was observed for fullness and desire to eat . The results of this study show that a new composite satiety ingredient comprised of a viscous fibre and whole-grain corn flour can affect acute satiety responses in men and women
