Fatty Liver Disease (NAFLD/MASLD): The Nutrition Evidence Guide

Fatty liver disease — now called MASLD — affects about 1 in 3 Americans. It happens when too much fat builds up inside liver cells. Most people have no symptoms, but over time it can progress to serious liver damage. The good news: it's one of the most responsive conditions to diet changes in medicine.

The most important thing you can do is lose 5–10% of your body weight if you're overweight. Research confirmed that this level of weight loss significantly reduces liver fat. Losing 10% or more can reverse the disease in most people.

Two specific things to cut: added sugars and sugar-sweetened drinks. Fructose — the type of sugar in sodas, juices, and many packaged foods — goes straight to the liver and drives fat production there. Cutting sugary drinks alone can show results in 8–10 weeks.

Replace refined carbohydrates with vegetables, legumes, and whole foods. Eat fatty fish like salmon 2–3 times a week — the omega-3 fats have been shown to directly reduce liver fat.

Coffee is actually protective. Studies show two or more cups a day is linked to lower risk of liver scarring. Black coffee, no added sugar.

Exercise also helps — even without weight loss.
