The Claim

Dietary fiber intake is linearly associated with lower visceral fat volume up to 35 g/day, with a stronger association in women than in men, as indicated by a statistically significant sex interaction (P=0.012).

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Higher dietary fiber intake up to 35 grams per day is linked to lower visceral fat, and this link is stronger in women than in men.

See the scientific wording

The association between dietary fiber intake and lower visceral fat volume is linear across intake levels up to 35 g/day and is stronger in women than in men, with a statistically significant interaction by sex (P=0.012), indicating sex-specific effects that may inform targeted dietary recommendations.

Why this might work

When fiber is eaten, gut bacteria break it down into acids that signal the gut to release hormones. These hormones slow down digestion and reduce fat storage in the belly, especially in women, because their bodies respond more strongly to these signals.

    Eating more fiber is linked to less belly fat, and this link gets stronger as people eat up to 35 grams of fiber a day — especially in women. The study shows women benefit more than men from eating more fiber.
