The Claim

Dietary fiber intake is linearly associated with lower visceral fat volume up to 35 grams per day, with no evidence of a threshold effect beyond this intake level.

In plain English

People who consume more dietary fiber up to 35 grams per day have lower volumes of visceral fat, and this relationship continues to hold without leveling off at that intake level.

See the scientific wording

The association between dietary fiber intake and lower visceral fat volume is linear up to 35 g/day and does not show evidence of a threshold effect, suggesting that increasing fiber intake within typical dietary ranges continues to confer benefit.

Why this might work

When fiber reaches the gut, bacteria break it down and produce molecules that signal the intestines to release hormones. These hormones tell the liver to make less fat and store less fat in the belly area. More fiber means more of these molecules, so the liver keeps making less fat as fiber intake goes up.

    Eating more fiber, up to 35 grams a day, is linked to steadily less belly fat — each extra gram seems to help a little more, with no sign that it stops working. After 35 grams, it still helps, but the study didn’t have enough people eating way more to be sure.
