The Claim

Dietary fiber intake among U.S. adults aged 20–59 is below recommended levels (mean 17.5 g/day compared to 21–38 g/day), and higher dietary fiber intake is associated with lower visceral fat mass.

In plain English

U.S. adults aged 20–59 consume less dietary fiber than recommended, and those who eat more fiber have less visceral fat.

See the scientific wording

Dietary fiber intake in U.S. adults aged 20–59 is below recommended levels (mean 17.5 g/day vs. 21–38 g/day), and higher intake is associated with lower visceral fat, suggesting widespread fiber inadequacy may contribute to elevated metabolic risk.

Why this might work

When fiber reaches the gut, bacteria break it down and produce chemicals that tell the liver to make less fat and tell fat cells to burn more fat, leading to less fat buildup around organs.

    People who eat more fiber tend to have less fat around their organs, even if they weigh the same. Most U.S. adults eat less fiber than doctors recommend, and this study shows that eating more fiber is linked to less harmful belly fat.
