People with fatty liver disease make more of their own fat inside the liver than healthy people—about 23% of the fat in their liver comes from this internal process, compared to just 10% in people without the disease.

In people with fatty liver disease, the liver makes way more of its own fat from scratch than it should, but the fat we eat or that’s in our blood doesn’t change — it’s the liver’s internal fat factory going into overdrive.

People with NAFLD—where fat builds up in the liver without drinking alcohol—often also have issues like being overweight, having high blood sugar, or other metabolic problems.

Eating fewer carbs and more protein for a week might help turn off fat-making genes and turn on fat-burning and metabolism genes in the livers of obese people with fatty liver disease.

If you're an obese adult with fatty liver, going on a low-carb diet for just two weeks—even without cutting calories—might slash your liver's fat production by nearly 80% and boost fat burning in your body by almost 5 times.

If you're an obese adult with fatty liver disease, switching to a very low-carb, high-fat diet for just two weeks might cut your liver fat by nearly half—and you could see improvements in as little as one day.
