The Claim

In adults with abdominal obesity and dyslipidemia, a Mediterranean/low-carbohydrate diet with daily walnut consumption reduces hepatic fat content by 41% after 6 months and by 29% after 18 months compared to a low-fat diet, independent of changes in visceral fat mass, and this reduction is associated with improved markers of liver function and glycemic control.

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

Cause and effect
1 study reviewed
In plain English

In adults with abdominal obesity and high blood fats, eating a Mediterranean or low-carbohydrate diet with daily walnuts reduces liver fat by 41% after six months and 29% after 18 months more than a low-fat diet, and this reduction occurs alongside better liver and blood sugar markers.

See the scientific wording

In adults with abdominal obesity and dyslipidemia, a Mediterranean/low-carbohydrate diet with daily walnut consumption reduces hepatic fat content by 41% after 6 months and 29% after 18 months, more than a low-fat diet, independent of visceral fat loss, and this reduction is linked to improved markers of liver function and glycemic control.

Why this might work

Eating fewer carbs and more healthy fats from nuts and olive oil tells the liver to stop making new fat and start burning existing fat. This clears fat out of the liver, which lets the liver respond better to insulin and release less sugar into the blood. It also stops the liver from releasing harmful signals that cause inflammation, which improves liver health and blood sugar control.

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

    People with belly fat and high cholesterol who ate a Mediterranean-style diet with walnuts and fewer carbs lost more fat from their liver than those on a low-fat diet — even if they didn’t lose more belly fat. Their liver and blood sugar also got healthier.
