Fatty Liver Diet: What to Eat, What to Avoid, and Why

TL;DR

• The best-supported fatty liver diet is a calorie-aware, Mediterranean-style pattern: vegetables, legumes, whole grains, fish, nuts and olive oil, with very little added sugar, sugary drinks, refined carbs, processed meat or alcohol.
• If you’re overweight, guidelines aim for losing at least 5% of body weight to reduce liver fat, 7–10% to improve inflammation, and 10% or more to improve fibrosis.
• Build each plate around vegetables, add a palm of protein and a fist of whole grains, use olive oil as your main fat, and drink water, coffee or tea instead of anything sweet.

The best diet for fatty liver is a Mediterranean-style way of eating that also helps you eat a little less: mostly vegetables, legumes, whole grains, fish, nuts and olive oil, with very little added sugar, sugary drinks, refined starch, processed meat or alcohol. If you carry extra weight, losing 5–10% of it is the most powerful thing the diet can do for your liver.

That advice isn’t a fad. It comes from the two main liver guidelines for MASLD (metabolic dysfunction-associated steatotic liver disease, formerly NAFLD): the American Association for the Study of Liver Diseases (AASLD) 2023 practice guidance and the 2024 European EASL–EASD–EASO guideline. This guide explains what to eat, what to limit, why each piece matters, and how to turn it into meals.

What Is a Fatty Liver Diet?

A fatty liver diet isn’t a branded plan. It’s a set of changes aimed at the things that put fat into the liver in the first place.

Your liver stores fat when energy coming in regularly exceeds what your body can use. The AASLD guidance explains that when intake outstrips needs, dietary sugars (fructose, sucrose and glucose) drive the liver to make new fat. It also notes that excessive fructose raises the risk of fatty liver, MASH (the inflamed form) and advanced fibrosis independent of calorie intake. That’s why sugar gets special attention.

So a fatty liver diet has four jobs:

1. Create a modest calorie deficit if you’re overweight, so the liver can use up stored fat.
2. Cut the sugars that the liver turns into fat, especially sugary drinks and juice.
3. Swap saturated fat for unsaturated fat, mainly olive oil, nuts and fish.
4. Remove or minimize alcohol, which adds its own damage.

Everything else, from the plate method to the shopping list, is a practical way to do those four things.

How Much Weight Do You Need to Lose With Fatty Liver?

If you’re overweight, weight loss is the change with the strongest evidence. The 2024 EASL–EASD–EASO guideline recommends that diet-induced weight loss aim at a sustained reduction of:

Weight loss (of starting weight)	What it can do	Example for someone who weighs 200 lb (91 kg)
At least 5%	Reduce liver fat	10 lb (4.5 kg)
7–10%	Improve liver inflammation	14–20 lb (6.4–9.1 kg)
10% or more	Improve fibrosis (scarring)	20 lb (9.1 kg) or more

The AASLD guidance puts it a little differently: loss of 3–5% improves liver fat, but greater loss (more than 10%) is generally needed to improve MASH and fibrosis. Both say the same thing in practice. Even modest weight loss helps, and more (kept off) helps more.

A few points that matter in real life:

• Slow and steady is the goal. The word that matters in the guideline is sustained. A crash diet you abandon in a month does less for your liver than a moderate change you keep for years.
• Normal weight doesn’t mean diet doesn’t matter. The European guideline still recommends diet and exercise for normal-weight adults with MASLD to reduce liver fat.
• You don’t need an extreme diet. The AASLD notes that low-carb, low-fat, Mediterranean and intermittent fasting approaches, and different levels of calorie cutting, appear comparable at improving fatty liver. The best diet is the one you can keep.

Why Sugar and Refined Carbs Matter So Much

Added sugar is the part of the diet most tightly linked to fatty liver, and sugary drinks are the worst form of it.

The European guideline recommends avoiding sugar-sweetened beverages outright, and cites a prospective cohort study in which drinking four or more servings of soft drinks a week was linked to a 45% higher risk of developing MASLD. NIDDK, part of the US National Institutes of Health, advises avoiding foods and drinks with large amounts of simple sugars, especially fructose, and names sweetened soft drinks, sports drinks, sweetened tea and juices. It also points out that table sugar (sucrose) is quickly split into glucose and fructose during digestion. “It’s not high-fructose corn syrup” doesn’t make a drink safe.

To give a sense of scale, USDA data show a regular 12-oz cola carries about 37 g of sugar. The American Heart Association suggests keeping added sugar to about 25 g a day for most women and 36 g for most men, so one can uses up a whole day’s budget.

Refined carbohydrates (white bread, white rice, pastries, most breakfast cereals, crackers) are the next layer. The AASLD links diets heavy in refined carbs and saturated fat to fatty liver, and recommends diets with limited carbohydrates, higher fiber and unsaturated fats “when possible”. You don’t need to go low-carb. Trade refined carbs for whole ones and keep portions moderate.

For the full list, see our guide to foods to avoid with fatty liver.

Which Fats Are Better for a Fatty Liver?

Fat isn’t the enemy, but the type matters. The European guideline notes that saturated fat has worsened liver fat in several short-term trials, and NIDDK recommends replacing saturated and trans fats with unsaturated fats, especially omega-3s.

Here is how two common cooking fats compare, per tablespoon (USDA FoodData Central):

Fat (1 tbsp)	Calories	Saturated fat	Monounsaturated fat
Olive oil	119	1.9 g	9.8 g
Butter, salted	102	7.3 g	3.0 g

Olive oil has slightly more calories but about a quarter of the saturated fat. It’s also the main fat of the Mediterranean diet. The practical rule is to cook with olive oil, snack on nuts, eat fish a couple of times a week, and keep butter, cream, fatty cheese, fatty and processed meats and fried foods as occasional foods.

All fats are calorie-dense, including the good ones. A tablespoon of olive oil is about 120 calories, so measure it rather than pouring freely.

Is Alcohol Off the Table With Fatty Liver?

For many people, yes. The AASLD guidance says that people with clinically significant fibrosis (stage F2 or higher) should abstain from alcohol completely. The European guideline says all alcohol should be stopped completely and permanently in advanced fibrosis or cirrhosis.

If you don’t have significant fibrosis, the guidance still leans toward less. The European guideline recommends discouraging alcohol in everyone with steatotic liver disease. It also says emerging evidence does not support the old idea that light-to-moderate drinking protects the liver, particularly in people with cardiometabolic risk factors. If you don’t know your fibrosis stage, ask your doctor before assuming any amount is safe. We cover the details in is alcohol safe with fatty liver?

Why the Mediterranean Diet Is the Default

Both guidelines point to the Mediterranean diet. The European guideline recommends improving diet quality “similar to the Mediterranean dietary pattern”, limiting ultra-processed food and avoiding sugar-sweetened beverages. It describes the pattern as high in olive oil, vegetables, fruits, nuts and seeds, legumes, whole grains, fish and seafood, and low in sugars, refined carbs, saturated fat, ultra-processed foods and red and processed meat.

Why this pattern rather than any other?

• It works on liver fat, sometimes even without weight loss. The European guideline notes the Mediterranean diet has repeatedly shown liver and heart benefits, even without weight loss.
• It protects the heart. People with MASLD often also have heart and metabolic risks, and the AASLD notes the Mediterranean diet is sustainable and has cardiovascular benefit.
• It’s livable. Nothing is banned outright. It’s normal food, which is why people can keep eating this way.

The AASLD also notes the pattern may not suit every culture as-is, and that similar changes adapted to your own food traditions may make them easier to keep. Beans and rice, dal and vegetables, or grilled fish with greens all fit if the principles hold.

Foods to Eat and Foods to Limit

Food group	Eat more often	Eat less often
Vegetables	All kinds, especially leafy greens, cruciferous vegetables, tomatoes, peppers	Fried vegetables, veggies in cream or cheese sauces
Fruit	Whole fruit, berries	Juice, sweetened smoothies, canned fruit in syrup
Grains	Oats, whole-wheat bread, brown rice, quinoa, barley, whole-wheat pasta	White bread, pastries, sugary cereals, crackers
Protein	Fish, legumes, poultry, eggs, tofu, plain yogurt	Bacon, sausage, deli meats, hot dogs, fatty red meat
Fats	Olive oil, nuts, seeds, avocado	Butter, cream, lard, fried foods
Drinks	Water, coffee, tea (unsweetened)	Soda, juice, sweet tea, energy drinks, alcohol
Snacks	Nuts, fruit, vegetables with hummus, plain yogurt	Chips, candy, cookies, pastries

Does Coffee Help Fatty Liver?

Coffee is one of the few single foods liver guidelines mention by name. The AASLD guidance says coffee, caffeinated or not, may be beneficial, and that drinking three or more cups a day could be recommended if you have no reason to avoid it, based on the lower risk of fatty liver and fibrosis seen in epidemiological studies. The European guideline agrees that coffee is linked to less liver damage in observational studies, but adds that trials are scarce, so firm conclusions can’t be drawn.

In practice, if you already enjoy coffee, keep it, and keep it plain or with a little milk. A large flavored latte is a sugary drink. More on this in is coffee good for fatty liver?

A Simple Plate Method for Fatty Liver

You don’t need to count every gram to eat this way. Use a standard dinner plate (about 9–10 inches) and build it like this:

• Half the plate: non-starchy vegetables. Salad, roasted or steamed vegetables, soup, or a mix.
• A quarter: protein. About the size of your palm: fish, chicken, eggs, tofu, or a cup of beans or lentils.
• A quarter: whole grains or starchy vegetables. About a fist: brown rice, quinoa, whole-wheat pasta, a small potato with skin, corn or sweet potato.
• A thumb of healthy fat. About a tablespoon of olive oil for cooking or dressing, or a small handful of nuts or seeds.
• Water, coffee or tea to drink. Fruit if you want something sweet afterward.

This does three things at once. It cuts calories without leaving you hungry (vegetables and beans are filling), shrinks the refined-carb portion, and makes olive oil and nuts your default fats. For a week of meals built this way, see our 7-day fatty liver meal plan.

Do Calories Still Count?

Yes. The AASLD guidance says people with MASLD who are overweight should be prescribed a diet that leads to a calorie deficit. Food quality and quantity work together. Olive oil and nuts are good for you but easy to overeat, and a “healthy” smoothie can carry as much sugar as a soda.

Some approaches get a lot of attention without strong liver evidence behind them:

• Very low-carb keto: the European guideline says there is currently insufficient evidence on its efficacy or safety in MASLD.
• Intermittent fasting: the same guideline found very little evidence that time-restricted eating reduces liver fat more than regular calorie reduction.
• Low-carb versus low-fat: reduced-calorie versions of both appear similarly effective at lowering liver fat, with the Mediterranean diet adding extra value and being easier to maintain.

How Does Exercise Fit In?

Diet and activity work together. The European guideline recommends more than 150 minutes a week of moderate activity or 75 minutes of vigorous activity, tailored to your preferences and abilities, and less time sitting. It prefers a combination of aerobic and resistance training. The AASLD notes that in some studies, simply increasing activity by more than 60 minutes a week helped prevent or improve fatty liver. Exercise helps the liver even without weight loss, so it counts even when the scale doesn’t move.

What About Supplements and Medicines?

Supplements are not a shortcut. The European guideline says nutraceuticals (food supplements, herbal products and similar) cannot be recommended because there isn’t enough evidence of their effectiveness or safety. The AASLD guidance says silymarin (milk thistle) should not be used to treat MASH, and that omega-3 supplements have not shown liver-specific benefits. Always check with your doctor before starting any supplement.

On medicines, the FDA has given accelerated approval to two drugs for adults with MASH and moderate-to-advanced fibrosis without cirrhosis: resmetirom (Rezdiffra) in March 2024 and semaglutide (Wegovy) in August 2025. They’re prescribed alongside diet and exercise, not instead of them, and whether one is right for you is a question for your hepatologist.

If You Have Cirrhosis, the Rules Change

Everything above is for fatty liver without cirrhosis. With cirrhosis, especially with muscle loss or decompensation, the European guideline recommends a high-protein diet and a late-evening snack, and any weight loss has to protect muscle. People with fluid buildup (ascites) are usually given a sodium limit as well. If that’s you, follow your care team’s plan and read our cirrhosis diet guide rather than this one.

How to Start This Week

Changing everything on Monday rarely lasts. Try one change at a time:

1. Replace every sugary drink with water, sparkling water, coffee or tea. For many people this is the single biggest win.
2. Switch your cooking fat to olive oil and measure it with a spoon.
3. Fill half your plate with vegetables at lunch and dinner.
4. Swap one refined grain for a whole one, such as white rice to brown rice or white bread to whole-wheat.
5. Eat fish twice and legumes three times this week.
6. Set an alcohol plan with your doctor, and if you have significant fibrosis, that plan is zero.
7. Move a little more. A brisk walk after dinner counts.

Some people find it easier to see where their sugar and saturated fat are really coming from by tracking for a week or two. An app like Liverly can scan a meal and give it a Liver Score, so you can spot the drinks, sauces and snacks quietly adding up.

The Bottom Line

The fatty liver diet that guidelines support is Mediterranean-style eating with a calorie deficit when you need one. That means plenty of vegetables, legumes, whole grains, fish, nuts and olive oil, very little added sugar and refined starch, no sugary drinks, less saturated fat and processed meat, and as little alcohol as possible (none with significant fibrosis). If you’re overweight, losing and keeping off 5–10% of your weight gives your liver its best chance to improve. Start with the change you’re most likely to keep, and let your doctor track how your liver responds.
