Could FOS Help With Weight Loss?

 FOS, otherwise known as

fructo-oligosaccharide is a type of

prebiotic fibre found in chicory

and is used primarly as a supplement

to help feed friendly bacteria in




the gut. In a recent study, researchers at the University of Mastricht suggested that it

might have a role to play in weight loss.  31 healthy subjects with a BMI of around

24.8kg / m2 were randomised to receive either 10g FOS, 16g FOS or 16g of a

placebo powder daily. for 13 days. At the end of the trial period the energy

consumption of those taking the higher dose of FOS had gone down by 11%.

They also reported feeling fuller, reflecting their lowered need for food.

The study was of insufficient duration to see whether weight loss occurred,

but if the decreased intake of calories continued then it is likely that this would

lead to weight loss.
