Fatty liver disease is one of the most common liver conditions worldwide, affecting roughly one in three adults. Yet many people don't know they have it until routine bloodwork or imaging raises concerns.

The condition develops when excess fat accumulates in liver cells. Over time, some people develop inflammation and scarring, potentially progressing to cirrhosis and other serious complications.

Previously called non-alcoholic fatty liver disease (NAFLD), the condition is now commonly known as metabolic dysfunction-associated steatotic liver disease (MASLD). The updated terminology reflects its close relationship with metabolic conditions such as insulin resistance, type 2 diabetes, and abdominal obesity.

The encouraging news is that fatty liver disease can often improve with changes to diet and lifestyle, especially before significant liver scarring develops.

How Nutrition Supports Liver Health

According to the 2024 European clinical guidelines for MASLD, dietary changes and physical activity are central to managing the condition.

Research consistently supports Mediterranean-style eating, which emphasizes vegetables, fruit, legumes, whole grains, fish, nuts, seeds, and olive oil.

These foods provide fibre, unsaturated fats, and essential nutrients that support metabolic health. Fibre-rich foods can help with blood sugar and cholesterol management, while replacing saturated fats with unsaturated fats can improve cardiovascular risk factors that frequently accompany fatty liver disease.

For people with excess weight, sustained weight loss of approximately 5 per cent can reduce liver fat, though larger reductions may be needed to improve inflammation and scarring. But, improving diet quality and staying physically active can provide benefits even without significant weight loss.

Foods to Eat More Often and What to Limit

Building a liver-friendly diet doesn't mean eliminating carbohydrates, avoiding all fats, or following complicated food rules.

Instead, focus on adding more vegetables, berries, beans, lentils, oats, quinoa, fatty fish, nuts, seeds, and extra-virgin olive oil to everyday meals.

At the same time, reducing sugary drinks, highly processed foods, processed meats, and foods high in saturated fat can help improve overall diet quality. Alcohol can also contribute to liver damage, so people diagnosed with fatty liver disease should discuss alcohol avoidance with their healthcare provider.

There's no need to rely on expensive supplements, juice cleanses, or products marketed as liver detoxes. Some herbal supplements can even cause liver injury.

Can Fatty Liver Disease Be Reversed?

For many people, reducing liver fat is possible through sustained dietary and lifestyle changes. Early-stage disease may improve significantly, although advanced liver scarring is more difficult to reverse.

Managing related conditions, including type 2 diabetes, high cholesterol, and high blood pressure, is also important.

The most effective approach is one you can maintain. Rather than aiming for a perfect diet, focus on small, consistent improvements that support your liver and overall health.

If you've been diagnosed with fatty liver disease, work with your healthcare provider or a registered dietitian to develop an approach suited to your health needs.
