Nonalcoholic fatty liver disease (NAFLD), now called metabolic dysfunction-associated steatotic liver disease (MASLD), happens when too much fat builds up in the liver, even though a person drinks little or no alcohol. It is most commonly linked to conditions such as obesity, type 2 diabetes, insulin resistance, high cholesterol, high blood pressure, and metabolic syndrome. Over time, this excess fat can cause inflammation and liver damage if it is not addressed. The most important thing to understand is that fatty liver disease often develops silently, with few or no symptoms in its early stages. The good news is that early detection, healthy eating, regular physical activity, weight management, and proper medical care can often slow, stop, or even reverse the disease before permanent liver damage occurs.

The most important things people can do to help prevent nonalcoholic fatty liver disease (NAFLD), now called metabolic dysfunction-associated steatotic liver disease (MASLD), are to maintain a healthy weight, eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats, and stay physically active with regular exercise. It is also important to manage conditions such as type 2 diabetes, high blood pressure, and high cholesterol, avoid excessive alcohol consumption, avoid smoking, and attend regular medical checkups to identify liver problems early. Small, consistent lifestyle changes can significantly reduce the risk of developing fatty liver disease and support long-term liver health.
