The Claim

Higher dietary fiber intake is associated with a 0.97 percentage point reduction in liver fat content measured by MRI per unit increase in daily fiber intake, independent of genetic predisposition to MASLD and gut microbial butyrate levels.

Source: Dietary fiber intake, genetic predisposition of gut microbiota, and the risk of metabolic dysfunction-associated steatotic liver disease.

In plain English

For every additional gram of dietary fiber consumed daily, liver fat content measured by MRI decreases by 0.97 percentage points, regardless of genetic risk for MASLD or levels of butyrate-producing gut bacteria.

Higher dietary fiber intake is associated with a 0.97 percentage point reduction in liver fat content measured by MRI per unit increase in daily fiber intake, independent of genetic predisposition to MASLD and gut microbial butyrate levels.

Why this might work

When you eat more fiber, bacteria in your gut break it down and make a compound called butyrate. This compound travels to your liver and turns off genes that make fat, while turning on genes that burn fat. It also reduces inflammation in the liver, which stops excess fat from building up.

1 study
  1. Study: Dietary fiber intake, genetic predisposition of gut microbiota, and the risk of metabolic dysfunction-associated steatotic liver disease.

    People who eat more fiber tend to have less fat in their liver, even if they’re genetically prone to fatty liver or have different levels of good gut bacteria — this study found that link in over 190,000 people.
