Fatty Liver Diet: What to Eat to Reverse It
A scan picked something up, or a blood test came back slightly off, and fatty liver got mentioned on the way out of the room. Nobody explained it. By the time you were home, the internet had sold you a detox tea.
A fatty liver diet is not a cleanse and not a supplement. The 2024 European guideline puts numbers on it: a sustained loss of at least 5% of body weight to reduce liver fat, 7 to 10% to improve inflammation, at least 10% to improve fibrosis. At 80 kg (176 lb), the first step is 4 kg (8.8 lb).
The first thing I say to a client who has just been told this is that of all the things a liver can have, this is the one that answers to what she eats.
The second is that no tea is involved.
01The name changed in 2023, and your paperwork may say either
If your letter says NAFLD and a website says MASLD, they are the same condition. Rinella and colleagues, in the Journal of Hepatology in 2023, writing for a panel of the major liver societies, replaced non-alcoholic fatty liver disease with metabolic dysfunction-associated steatotic liver disease. NASH, the inflamed form, became MASH.
The old name defined the condition by what it was not, and most of the panel found "non-alcoholic" and "fatty" stigmatising. The new one names the driver, and the diagnosis now requires at least one of five cardiometabolic risk factors rather than ruling other causes out. The same statement created MetALD, which comes up under alcohol.
That is all the terminology you need. Everyone I work with calls it a fatty liver, so that is what I will call it.
02What is actually happening in there
Fat is being stored inside your liver cells in amounts that do not belong there, and in most cases the engine behind it is insulin resistance. That is why a fatty liver travels alongside prediabetes, PCOS and weight around the middle. The insulin resistance article explains the mechanism properly.
One distinction is worth holding onto. Fat on its own is one thing. Fat plus inflammation and cell damage is the more serious form, and scarring, called fibrosis, decides how much this matters. You cannot tell which you have from how you feel.
03The number that matters is smaller than you fear
The 2024 EASL-EASD-EASO clinical practice guidelines on MASLD, a joint European liver, diabetes and obesity document, recommend that weight loss in adults with MASLD and overweight aim at a sustained reduction of at least 5% to reduce liver fat, 7 to 10% to improve liver inflammation, and at least 10% to improve fibrosis.
At 80 kg (176 lb): 5% is 4 kg (8.8 lb). 7% is 5.6 kg (12.3 lb). 10% is 8 kg (17.6 lb).
Four kilos. Not thirty. Not a dress size you last wore in your twenties.
The study underneath those thresholds: Vilar-Gomez and colleagues, in Gastroenterology in 2015, followed 293 people with biopsy-proven steatohepatitis through 52 weeks of lifestyle change and biopsied them again. Among those who lost 5% of body weight or more, 58% had resolution of steatohepatitis. Among those who reached 10% or more, 90% had resolution and 45% had regression of fibrosis. That is a study group with confirmed disease, not a promise to one person, and the weight has to stay off.
What I do with this in practice: we write the actual kilo figure down at the first appointment. Not a goal weight, not a BMI. Almost every woman has said some version of "is that all", and that is the useful part.
The fatty liver diet pattern with the most support behind it
The same European guideline recommends improving diet quality along the lines of a Mediterranean pattern, limiting ultra-processed food rich in sugars and saturated fat, and avoiding sugar-sweetened drinks. That is the closest thing to an official answer, and no single named diet has been proven better than the rest.
Ryan and colleagues, in the Journal of Hepatology in 2013, put twelve people with biopsy-proven fatty liver through a six-week crossover between a Mediterranean diet and low-fat, higher-carbohydrate advice, measuring liver fat by MR spectroscopy. Liver fat fell further on the Mediterranean diet, with no meaningful change in body weight. Twelve people is a small study, and it still suggests the shape of your food does something.
Build meals around these
Vegetables at lunch and dinner, in a quantity that looks slightly excessive.
Olive oil, nuts, seeds, avocado, oily fish. The type and the total matter, not fat itself.
Protein at every meal: fish, eggs, chicken, Greek yogurt, lentils, beans, tofu.
Slower carbohydrates in sensible portions: oats, rye bread, barley, quinoa, potatoes.
Whole fruit and berries, which are not the fructose problem.
Cut back on these
Sugar-sweetened drinks, including juice and energy drinks. The clearest item here.
Ultra-processed food carrying added sugar and saturated fat, as an everyday staple.
Refined starch eaten alone: pastries, biscuits, white bread with nothing on it.
Frequent processed meat, deep-fried food and butter-heavy cooking.
Alcohol, in the honest way described below rather than the guilty way.
Where the evidence is firm and where I am extrapolating: avoiding sugary drinks and limiting ultra-processed food sit inside a strong guideline recommendation. Refined starch on its own has less direct evidence here, and I suggest pulling back for what it does to the metabolic picture underneath. Enough to say cut back, not to call proven.
Whole fruit is not the problem. The fructose that matters arrives in a glass, without fibre attached. If prediabetes sits behind your result, the prediabetes guide and the blood sugar food guide go deeper.
05Alcohol, coffee and moving your body
Alcohol, honestly
The definition is metabolic now, and alcohol did not stop counting. The 2023 nomenclature statement created MetALD for people who have metabolic risk factors and also drink more than a modest amount, because both work on the same organ and having one does not excuse the other.
The European guideline discourages alcohol in anyone with a fatty liver, particularly as intake rises, and says it should stop completely and permanently in advanced fibrosis or cirrhosis. I will not hand you a safe number from a web page, because your stage, your medicines and your drinking pattern change that answer.
Coffee, the one bit of good news
The 2023 AASLD practice guidance notes that coffee, caffeinated or not, at three cups a day or more is associated with less advanced liver disease. The European guideline labels that evidence observational, which is the honest label. Association is not causation, so nobody can tell you coffee treats a fatty liver.
If you drink it, no reason to stop for your liver. If you do not, this is not a prescription to start. A large sweetened coffee drink is a sugary drink wearing a hat.
Movement, including on the weeks the scale will not move
This is the part I most want you to hear if you have been told to lose weight and cannot. The European guideline recommends physical activity to reduce liver fat, preferably more than 150 minutes a week of moderate or 75 minutes of vigorous activity. It also recommends diet and exercise for adults with a fatty liver who are already at a normal weight, so the benefit is not conditional on the scale. The walk counts. The dumbbells count.
06A normal day of eating
Nothing here is special or expensive. This is a Tuesday.
Breakfast
150 g (5 oz) plain Greek yogurt with 100 g (3.5 oz) berries, 30 g (1 oz) oats and 15 g (0.5 oz) walnuts. Coffee, black or with milk.
Lunch
120 g (4 oz) tinned or grilled fish over a large salad with 100 g (3.5 oz) cooked lentils, tomatoes and cucumber, dressed with 10 g (0.4 oz) olive oil and lemon. A slice of rye bread.
Snack
An apple with a small handful of almonds, or 150 g (5 oz) cottage cheese. Water rather than juice. Then a 15 minute walk after dinner.
Dinner
150 g (5 oz) chicken, salmon or white beans with 200 g (7 oz) vegetables roasted at 200°C (400°F) in olive oil, and 180 g (6 oz) potatoes or 60 g (2 oz) dry weight barley.
Protein turns up at every meal, and bread, oats and potatoes are still allowed. A fatty liver diet plan is not a low-carb contest. Treat the 50 healthy meal ideas as a bank to pull from.

The honest one first, because there is a real guideline position and it is narrow. The 2023 AASLD practice guidance says vitamin E may be considered in selected adults with biopsy-proven steatohepatitis who do not have diabetes. The same guidance says the data show no antifibrotic benefit and that it has not been carefully studied in cirrhosis. The 2024 European guideline goes further and does not recommend vitamin E for MASH at all.
One narrow group, confirmed on biopsy, no diabetes, decided by a specialist who knows your other conditions and medicines. I am deliberately not printing a dose.
Now the part I will not soften.
"Liver detox", "liver cleanse" and milk thistle products do not have the evidence their marketing implies. Neither the American nor the European guidance lists them as a treatment. Your liver is the organ that does detoxification and it does not need a tea to be allowed to. A fatty liver is not full of toxins, it is storing fat because of how your metabolism is running. I am blunt about it because taking one feels like doing something, which delays the thing that works.
08What food cannot do, and what to ask your doctor
All of this is nutrition support. It is not medical advice, it is not a diagnosis, and it does not replace your doctor.
Do not diagnose yourself from symptoms. Early fatty liver usually has none, which is why it turns up by accident on a scan, and tiredness is not a liver test. Do not stop, reduce or change any prescribed medicine because of something you read, unless the clinician who prescribed it says so.
Two questions for your next appointment: which stage am I at, and has my fibrosis been assessed? Scarring is checked with the FIB-4 score, elastography and occasionally a biopsy, and the answer changes what happens next.
If you have advanced fibrosis or cirrhosis, general weight-loss advice does not apply to you and some of it could do harm. Protein needs, muscle preservation and energy intake can run opposite to what you would expect, and that needs a dietitian alongside your liver team. Rapid or extreme weight loss is not the goal for anyone reading this.
Treatment has moved too. Resmetirom was approved in the United States in 2024 for adults with non-cirrhotic MASH and moderate to advanced fibrosis, semaglutide received a MASH indication there in 2025, and the European guideline says resmetirom can be considered where approved locally. I mention it so you see why your stage matters, not to suggest it. That conversation belongs to you and your doctor.
Four kilos, a changed shopping list, a walk most days, and time. That is the plan, and it beats anything in the supplement aisle.
Frequently asked questions
What is the best diet for a fatty liver?
No single fatty liver diet has been proven better than every other one. The 2024 EASL-EASD-EASO guideline recommends a Mediterranean-style pattern, less ultra-processed food rich in sugars and saturated fat, and no sugar-sweetened drinks.
How much weight do I need to lose to reverse fatty liver?
For adults with MASLD and overweight, the 2024 European guideline recommends a sustained loss of at least 5% of body weight to reduce liver fat, 7 to 10% to improve inflammation, and at least 10% to improve fibrosis. At 80 kg (176 lb), that first step is 4 kg (8.8 lb).
What foods should I avoid with a fatty liver?
Sugar-sweetened drinks carry the firmest guideline position against them, followed by ultra-processed food rich in added sugar and saturated fat. Alcohol still counts. Whole fruit is not on the list.
Can fatty liver be reversed?
Fat inside liver cells can reduce, and at earlier stages the liver can look normal again. Scarring is separate: some fibrosis improves with sustained weight loss, and advanced scarring is managed rather than undone. Which applies to you depends on your stage.
Do liver detox supplements work for fatty liver?
No. Liver cleanses, detox teas and milk thistle products do not have the evidence their marketing implies, and neither the American nor the European guidance lists them as a treatment. Vitamin E has a narrow position that applies to selected patients under specialist care.
