The Claim
Among Japanese men, dietary fiber from beans, vegetables, and fruits is associated with lower visceral fat volume, while cereal fiber is associated with a trend toward higher visceral fat volume (P-trend = 0.05), indicating that the source of dietary fiber is related to differences in visceral fat volume.
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 Japanese men, fiber from beans, vegetables, and fruits is linked to lower visceral fat, while fiber from cereals is linked to slightly higher visceral fat.
See the scientific wording
Among Japanese men, dietary fiber from beans, vegetables, and fruits is associated with lower visceral fat volume, while cereal fiber shows a trend toward higher visceral fat volume (P-trend = 0.05), suggesting the source of fiber matters for abdominal fat regulation.
Fiber from beans, vegetables, and fruits feeds gut bacteria that make compounds that strengthen the gut lining and reduce body-wide inflammation, leading to less fat around the organs. Fiber from grains does not feed these bacteria as well and instead triggers the liver to make more fat, which collects around the abdomen.
What the research says
1 studyIn Japanese men, eating more fiber from beans, veggies, and fruit is linked to less belly fat, while eating more fiber from grains like rice and bread is slightly linked to more belly fat — though that second link isn’t super strong.
