The Claim

Acute ingestion of 20 grams of fructooligosaccharide or partially hydrolyzed guar gum has no effect on subjective feelings of hunger, satiety, or desire to eat in healthy young adults.

Description
1 study reviewed
In plain English

Eating 20 grams of fructooligosaccharide or partially hydrolyzed guar gum does not change how hungry, full, or eager to eat people feel in the short term.

See the scientific wording

Acute ingestion of 20 grams of fructooligosaccharide or partially hydrolyzed guar gum does not alter subjective feelings of hunger, satiety, or desire to eat in healthy young adults, indicating these fibers do not acutely influence appetite regulation through these perceptual pathways.

Why this might work

When these fibers are swallowed, they pass through the stomach and small intestine without being broken down or triggering signals that tell the brain the stomach is full or empty. Because no chemical or mechanical signals are sent from the gut to the brain about food intake, the person does not feel hungrier, fuller, or more eager to eat.

  1. Study: Acute intake of fructooligosaccharide and partially hydrolyzed guar gum on gastrointestinal transit: A randomized crossover clinical trial.

    This study gave people 20 grams of two types of fiber and found they didn’t feel hungrier, fuller, or more eager to eat than when they ate a placebo. So, these fibers don’t change how full or hungry you feel right after eating.
