The Claim
Higher dietary fiber intake is associated with lower visceral fat volume in U.S. adults aged 20–59, with a dose-dependent reduction of 4.1% to 7.6% across intake groups of 15–35 g/day compared to less than 15 g/day, after adjusting for age, sex, BMI, and lifestyle factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In U.S. adults aged 20–59, consuming more dietary fiber between 15 and 35 grams per day is linked to lower amounts of visceral fat compared to consuming less than 15 grams per day, with a measurable reduction of 4.1% to 7.6% across increasing intake levels.
See the scientific wording
Higher dietary fiber intake is associated with lower visceral fat volume in U.S. adults aged 20–59, with a dose-dependent reduction of 4.1% to 7.6% across intake groups of 15–35 g/day compared to less than 15 g/day, after adjusting for age, sex, BMI, and lifestyle factors, suggesting fiber intake may be a modifiable dietary target for reducing metabolically harmful abdominal fat.
When fiber is broken down by gut bacteria, it makes chemicals that tell the liver to stop making fat and tell fat cells to burn more fat, leading to less fat building up around the organs.
What the research says
1 studyPeople who eat more fiber—between 15 and 35 grams a day—tend to have less fat around their internal organs than those who eat less, even if they weigh the same. This link was found in a large U.S. study that carefully accounted for age, sex, and activity level.
