The Claim

Reduction in hepatic fat content mediates a substantial portion of the greater improvements in cardiometabolic risk parameters observed with a Mediterranean/low-carbohydrate diet compared to a low-fat diet.

Source: The beneficial effects of Mediterranean diet over low-fat diet may be mediated by decreasing hepatic fat content.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

When people follow a Mediterranean or low-carbohydrate diet instead of a low-fat diet, the improvement in heart and metabolic health markers is largely explained by a reduction in liver fat.

See the scientific wording

The greater improvements in cardiometabolic risk parameters observed with a Mediterranean/low-carbohydrate diet compared to a low-fat diet are largely attenuated when accounting for changes in hepatic fat content, suggesting hepatic fat reduction mediates a substantial portion of the dietary benefit.

Why this might work

When liver fat decreases, the liver works better at controlling blood sugar and stops releasing harmful signals that cause inflammation. This makes the whole body more responsive to insulin and lowers the risk of heart and metabolic diseases.

  1. Study: The beneficial effects of Mediterranean diet over low-fat diet may be mediated by decreasing hepatic fat content.

    This study found that eating a Mediterranean low-carb diet helps your liver fat go down more than a low-fat diet, and that’s mostly why it’s better for your heart and metabolism—not just because you lose belly fat.
