Fatty liver (MASLD)

MASLD, NAFLD, and why the name changed

You may have been told non-alcoholic fatty liver disease, or NAFLD. In 2023 it was renamed MASLD — metabolic dysfunction-associated steatotic liver disease — and the change was not cosmetic. The old name defined the condition by what it was not. The new one names what it is: a liver manifestation of the same metabolic dysfunction behind insulin resistance, type 2 diabetes and central weight gain.

That reframing matters for treatment. It stops the liver being treated as an isolated organ problem and puts it where it belongs — alongside blood sugar, blood pressure and lipids, all of which tend to move in the same direction when the underlying dysfunction improves.

What actually reverses it

The evidence here is unusually specific, which is rare in nutrition and worth using:

• Around 5% weight loss reduces liver fat measurably
• Around 7–10% is where inflammation (steatohepatitis) improves, and where some people see fibrosis regress
• A Mediterranean pattern has the best evidence of any specific dietary approach, and appears to help somewhat independently of weight change
• Exercise helps even without weight loss — liver fat falls with activity alone, which matters for anyone whose weight has stalled
• Sugar-sweetened drinks and fructose are the single most useful target: the liver handles fructose differently, and liquid sugar is the form most consistently associated with liver fat
• Coffee has a genuinely protective association, one of the few times a popular belief survives scrutiny

Alcohol is definitional here. MASLD is diagnosed in the context of limited alcohol intake; where both metabolic dysfunction and higher alcohol intake are present, the category is different (MetALD) and so is the advice. It is worth being honest with your clinician about the amount, because it changes what you are being treated for.

Fibrosis is what determines the outcome

Fat in the liver is common and often benign. What changes the prognosis is fibrosis — scarring — and its stage is the most important number in your file. It is estimated non-invasively with scores such as FIB-4 and with elastography, both widely available.

This is worth knowing for two reasons. It tells you whether you are managing something quietly progressive or something incidental. And it is the number that moves, or does not, in response to the work — which makes it a far better measure of progress than the word "fatty" on an ultrasound report.

If nobody has staged your fibrosis, that is a reasonable thing to ask your physician for.

What the first appointment covers

• How the diagnosis was made — ultrasound, raised ALT, a scan for something else — and whether fibrosis has been staged
• The metabolic picture around it: HbA1c, lipids, blood pressure, waist
• Liquid sugar and fructose, specifically, before anything else
• Alcohol, asked plainly and without judgement, because it changes the diagnosis
• A realistic weight trajectory tied to the 5% and 10% thresholds rather than an arbitrary goal
• Activity, including what is possible on the days when it is not

When to see a doctor

Jaundice, swelling of the abdomen or legs, confusion, or vomiting blood are signs of advanced liver disease and need urgent medical attention, not dietary advice.

Staging, medication and monitoring are your physician's or hepatologist's. Nutrition is the main treatment for early MASLD, but it works alongside that assessment rather than as a substitute for it.

Booking, and what it costs

Two routes, and which one is cheaper depends entirely on your plan rather than on which sounds better.

Through insurance. Medical nutrition therapy is a covered benefit on many plans, sometimes with no copay at all. Booking runs through Fay Nutrition, which checks your benefits before the first appointment so you know the number in advance rather than six weeks later.

Self-pay. A flat $140 per session through CognitiveMind — no benefits check, no prior authorization, no denial arriving after the fact. If your coverage is thin, absent, or has a deductible you will not meet this year, this is often the more predictable of the two.
