The Claim

Higher dietary fiber intake is inversely associated with visceral fat volume after adjustment for body mass index, age, sex, and lifestyle factors.

In plain English

People who consume more dietary fiber tend to have lower volumes of visceral fat, even when accounting for their body weight, age, sex, and lifestyle habits.

See the scientific wording

The inverse association between dietary fiber intake and visceral fat volume remains statistically significant after adjusting for body mass index, age, sex, and lifestyle factors, suggesting fiber’s effect on visceral fat is independent of overall adiposity.

Why this might work

When fiber passes through the gut, bacteria break it down and produce short-chain fatty acids. These acids make the gut move food faster, so less energy is absorbed from food. This means fewer calories turn into fat around the organs, even when total body weight stays the same.

    Even if two people weigh the same, the one who eats more fiber tends to have less fat around their organs — meaning fiber might help target belly fat specifically, not just help with overall weight loss.
