The Claim

In overweight adults with elevated liver fat, switching to an isocaloric diet low in glycemic index and saturated fat for two weeks reduces intrahepatic lipid content below the 5% threshold used to diagnose non-alcoholic fatty liver disease (NAFL), indicating that improving dietary quality alone may reverse early-stage fatty liver without requiring weight loss.

In plain English

If you're overweight and have too much fat in your liver, just changing to a healthier diet—without losing weight—might actually reverse early fatty liver in as little as two weeks.

In overweight adults with elevated liver fat, a two-week isocaloric switch to a low-glycemic index and low-saturated fat diet can reduce intrahepatic lipid content below the 5% threshold used to diagnose non-alcoholic fatty liver (NAFL), suggesting that dietary quality improvements alone may reverse early-stage fatty liver without weight loss.
