Can fatty liver be reversed?

What the science says now

Can losing weight lower the fat in a fatty liver?

Yes. Doctors recommend weight loss to treat fatty liver disease, also called metabolic dysfunction-associated steatotic liver disease, or MASLD. Losing at least 3% to 5% of your body weight can reduce fat in the liver (NIDDK).
Official guidance for people.

What about inflammation and scarring?

You may need to lose up to 7% to 10% of your body weight to reduce liver inflammation and fibrosis, which is scarring (NIDDK). Doctors recommend losing weight gradually. Rapid weight loss and malnutrition can make liver disease worse.
Official guidance for people.

Does it all depend on the scale?

Not entirely. Physical activity alone, even without weight loss, is also beneficial (NIDDK).
Official guidance for people.

Does sugar matter?

It may. In a small trial, 15 adults with fatty liver took an experimental drug that stops the body from processing fructose, a sugar found in large amounts in soda and other sweet drinks. They had less fat in the liver and a better insulin response, and their weight did not change (Fatty liver improved when the body stopped processing fructose, a new trial finds · Nature Metabolism). That drug is not available to the public.
In people; trials.

How can I tell if my liver has scarring?

A large study followed 1,590 adults whose fatty liver was confirmed by biopsy. Some blood test panels spotted serious scarring fairly well, and a two-step approach that starts with a common liver enzyme test called GGT also did well (Fatty liver: blood test panels may soon spare some people a biopsy · Journal).
In people; observational.

What we don’t know yet

Our sources do not say that scarring fully goes away, or how much any one person can improve. The fructose trial was small and short, at 6 weeks. The blood panel study was done in people already sent for a biopsy, so results in a regular checkup could look different. The NIDDK page, last reviewed in April 2021, says no medicines were approved for fatty liver, but a newer story of ours mentions approved medicines, so ask your doctor what is available now.

When to talk to your doctor

Talk with your doctor before starting a weight-loss plan, and before using supplements or herbal remedies. Some herbal remedies can actually damage your liver. If you have type 2 diabetes, extra weight or past liver tests that were off, ask whether a simple scarring check, such as a blood score or a liver stiffness scan, makes sense for you.

Talk about it at dinner

Ask everyone at the table: what is one drink we could swap for water, sparkling water or unsweetened tea this week? Let each person invent a fun flavor, like a lemon slice or a few berries. Then plan a short walk together after dinner.
