The Claim
Among women in the U.S., dietary fiber intake above 13.8 grams per day is associated with significantly lower liver fat levels, while intake below this threshold shows no significant association, indicating a nonlinear, threshold-dependent relationship.
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. women, consuming more than 13.8 grams of dietary fiber per day is linked to lower levels of liver fat, while consuming less than this amount shows no consistent difference in liver fat levels.

When women eat more than 13.8 grams of fiber daily, gut bacteria break down the fiber into chemicals that signal the liver to stop making fat and start burning it instead. These chemicals also help the body use insulin better, which stops the liver from overproducing fat. Below this fiber amount, these signals don't turn on, so liver fat stays high.
What the research says
1 studyStudy: Exploring the association between dietary fiber intake and hepatic steatosis: insights from NHANES
This study found that women who eat more than about 14 grams of fiber a day have less fat in their liver, but eating less than that doesn’t help much — it’s like a switch that turns on only after you hit that amount.
