The first thing my father in law did after his fatty liver diagnosis was go to the supermarket and buy a bottle of milk thistle capsules, a "liver cleanse" tea and three bags of kale. The second thing he did, a week later, was ring me to ask why he was still hungry all the time and whether the tea was supposed to taste like that. Ray is not a natural dieter. He is a retired postman who likes a bacon sandwich, and what he needed was not a cleanse but a plain, sustainable way of eating and moving that his liver would thank him for and that he could keep doing at 65 and 75.
This is that plan. It draws on the trials that have actually measured liver fat and liver stiffness, not on wellness marketing, and it is written for someone who is starting from where Ray started: two and a half stone overweight, not very fit, and a bit frightened. It covers what to eat, what to cut, what to do if you already have cirrhosis (the advice flips in an important way), how to exercise safely, and the supplements that help versus those that hurt.
This article is for information only. If you have cirrhosis, kidney disease, diabetes on insulin, or are underweight, please have a dietitian or your liver team tailor these principles to you.
The three principles behind a liver friendly diet
Strip away the noise and every liver guideline, from EASL 2024 to AASLD 2023 to the British Liver Trust, agrees on three things.
- Reduce liver fat. That means a modest calorie deficit if you are overweight, and sharply less fructose and refined carbohydrate regardless of weight, because these are converted directly to liver fat.
- Eat a Mediterranean pattern. It is the only dietary pattern with randomised trial evidence of lowering liver fat independent of weight loss (Ryan 2013, where six weeks of Mediterranean eating cut liver fat by 39 percent versus 7 percent on a low fat diet, with no weight difference).
- Protect your muscle. Muscle is the liver's partner in handling glucose, and losing it makes fatty liver worse and cirrhosis dangerous. That means enough protein and resistance exercise, and it is the principle most weight loss advice gets wrong.
Foods to eat for liver health
| Food | Why it helps | How much |
|---|---|---|
| Coffee | Each daily cup linked to about 20 percent lower cirrhosis risk; lowers liver enzymes and fibrosis progression (Kennedy 2016) | 2 to 4 cups a day, black or with a little milk, no syrups |
| Extra virgin olive oil | Main fat in the Mediterranean trials; monounsaturated fat lowers liver fat compared with saturated fat (Luukkonen 2018) | 2 to 3 tablespoons a day in place of butter |
| Oily fish (salmon, sardines, mackerel, trout) | Omega 3 fats lower liver fat by around 10 to 15 percent in meta analyses (Parker 2012) | Two portions a week |
| Nuts, especially walnuts | Higher nut intake linked to about 15 percent lower fatty liver prevalence; walnuts improved liver fat in the PREDIMED sub study | A small handful (30 g) daily |
| Vegetables, especially leafy greens and cruciferous | Fibre feeds gut bacteria that reduce fat delivery to the liver; nitrate rich greens linked to lower fatty liver risk (Ivancovsky-Wajcman 2021) | Half the plate at lunch and dinner |
| Whole grains and legumes | Low glycaemic load reduces the insulin surges that push liver fat storage | Oats, barley, brown rice, lentils, chickpeas most days |
| Whole fruit and berries | Fibre slows fructose absorption so the liver is not flooded; berries in particular are rich in polyphenols | 2 to 3 portions a day; whole, not juiced |
| Eggs, poultry, dairy, tofu | Lean protein preserves muscle during weight loss and steadies appetite (Leidy 2015) | 25 to 30 g of protein at each meal |
| Green tea | Modest improvements in liver enzymes in trials; safe as a drink | Drink freely; avoid concentrated extract capsules |
Foods to avoid or limit with liver disease
| Food or drink | Why it harms | Practical rule |
|---|---|---|
| Sugary drinks, fruit juice, energy drinks | Fructose is processed almost entirely by the liver and turned into fat; one a day raises fatty liver odds by about 55 percent (Ma 2015) | Cut to zero. This is the single highest yield change |
| Alcohol | Direct liver toxin; combines multiplicatively with fatty liver | Under 14 units a week with a healthy liver; none if you have fibrosis or cirrhosis |
| Ultra processed foods | Drive overeating by about 500 kcal a day in controlled conditions (Hall 2019); higher intake linked to fatty liver and fibrosis | Crisps, pastries, biscuits, ready meals and fast food as occasional, not daily |
| White bread, white rice, sweets, cakes | High glycaemic load pushes the liver to make fat from glucose | Swap for wholegrain versions and smaller portions |
| Processed and fatty red meat | Saturated fat raises liver fat more than the same calories from unsaturated fat; processed meat linked to higher fatty liver and insulin resistance (Zelber-Sagi 2018) | Red meat once or twice a week, processed meat rarely |
| Added salt (if you have cirrhosis) | Drives fluid retention and ascites | Under 5 to 6 g of salt (2 g sodium) a day; no salt added at the table |
| Raw shellfish (if you have cirrhosis) | Vibrio infection can be fatal in cirrhosis | Avoid raw oysters and undercooked shellfish |
If you have cirrhosis: the advice flips
This section matters enormously and is widely misunderstood. If you have fatty liver or early fibrosis, moderate calorie restriction and weight loss are the goal. If you have cirrhosis, especially if it is decompensated, the priority becomes preventing muscle loss, and the advice is nearly the opposite of a weight loss diet.
A cirrhotic liver cannot store glucose properly, so after only a few hours without food the body starts breaking down muscle for fuel. An overnight fast in cirrhosis does the metabolic damage of a three day fast in a healthy person. Sarcopenia (muscle wasting) affects 40 to 70 percent of people with cirrhosis and roughly doubles mortality (EASL nutrition guideline 2019).
- Protein: 1.2 to 1.5 g per kg of body weight per day. For an 80 kg person that is 96 to 120 g, spread across four to six meals. The old advice to restrict protein in encephalopathy was wrong and has been abandoned.
- A late evening snack, every night. Around 50 g of carbohydrate with some protein (a bowl of cereal with milk, toast with peanut butter, yoghurt and oats) at bedtime. Trials show this improves muscle mass and quality of life (Plank 2008).
- Never skip breakfast. Eat within an hour of waking.
- Salt under 2 g sodium a day if you have fluid retention.
- Weight loss only under supervision and only if you are still obese; even then, protein stays high and loss is slow.
If you have been told you have cirrhosis and nobody has mentioned a bedtime snack or a protein target, ask. It is one of the most effective and least prescribed treatments in hepatology.
Exercise for liver disease: what works and what is safe
Exercise lowers liver fat even without weight loss. A meta analysis in the Journal of Hepatology found aerobic training cut liver fat by 20 to 30 percent on MRI with almost no change on the scales, and the American College of Sports Medicine 2023 statement recommends at least 150 minutes a week of moderate activity plus resistance training, noting that both types work and that any amount beats none.
A starter week if you are unfit
| Day | Weeks 1 to 4 | Weeks 5 to 12 |
|---|---|---|
| Monday | 20 minute brisk walk | 35 minute brisk walk, include a hill |
| Tuesday | Resistance: 2 sets each of sit to stand, wall press up, step up, band row | Resistance: 3 sets each, add goblet squat and dumbbell press |
| Wednesday | 20 minute walk or cycle | 35 minute walk, or 25 minutes on a bike |
| Thursday | Rest or gentle stretch | Resistance session as Tuesday |
| Friday | 20 minute walk | 35 minute walk with 4 one minute faster bursts |
| Saturday | Resistance session as Tuesday | Longer walk, swim or bike, 45 to 60 minutes easy |
| Sunday | Rest | Rest |
Ray began with the twenty minute walk and found it harder than he expected. By week eight he was doing forty minutes with his daughter along the canal and had bought a pair of dumbbells. The resistance work matters more than people think; a Japanese trial found that resistance training alone reduced liver fat and improved insulin sensitivity in people who could not manage aerobic exercise (Hashida 2017).
Exercise with cirrhosis
Exercise is safe and beneficial in compensated cirrhosis and improves muscle mass, fitness and quality of life (Aamann 2018). Three cautions: if you have large varices, avoid heavy straining lifts and breath holding, and get an endoscopy first; if you have ascites, walking and light resistance work are fine but avoid anything that raises abdominal pressure; and eat a protein snack within an hour of exercising, because your liver cannot buffer the energy demand the way a healthy one would.
How much weight to lose, and how fast
If you are overweight with fatty liver, the target is 7 to 10 percent of body weight over six to twelve months, losing 0.5 to 1 kg a week. Faster than that, particularly on very low calorie diets, can temporarily worsen liver inflammation and raises gallstone risk (see our gallstone prevention guide). Use the BMI calculator to find your healthy range and what 7 and 10 percent means in kilograms, and remember the lower thresholds if you are of South Asian, East Asian or Black heritage, where liver fat accumulates at lower BMIs.
Supplements: the honest list
| Supplement | Verdict | Evidence |
|---|---|---|
| Vitamin E 800 IU daily | Reasonable for non diabetics with steatohepatitis, on a doctor's advice | PIVENS trial: MASH resolved in 36 percent vs 21 percent (Sanyal 2010). Long term high doses have been linked to prostate cancer and bleeding, so not a casual choice |
| Omega 3 fish oil | Modest benefit for liver fat; eating oily fish is better | Meta analysis shows around 10 percent liver fat reduction (Parker 2012) |
| Vitamin D | Correct a deficiency; do not expect it to treat the liver | Trials of supplementation have not improved liver histology |
| Milk thistle (silymarin) | Safe but ineffective | A large trial found no benefit over placebo in hepatitis C (Fried 2012); no convincing MASLD data |
| "Liver detox" and "cleanse" products | Avoid | No evidence of benefit; some contain hepatotoxic herbs |
| Green tea extract capsules | Avoid | Concentrated extracts have caused acute liver injury; the drink is fine (Navarro 2014) |
| Kava, comfrey, chaparral, high dose niacin, anabolic steroids | Avoid | Documented causes of liver injury |
Ray's milk thistle went in the bin along with the cleanse tea. What replaced them cost less: a cafetière and a bag of decent coffee.
What a liver friendly day looks like
- Breakfast: Porridge made with milk, topped with berries and a spoon of chopped walnuts. Black coffee.
- Mid morning: An apple and a second coffee.
- Lunch: Lentil and roasted vegetable salad with feta, dressed with olive oil and lemon. Wholegrain pitta.
- Afternoon: Greek yoghurt with a few almonds. Green tea.
- Dinner: Grilled sardines or salmon, a large pile of greens cooked in olive oil and garlic, small portion of brown rice or new potatoes.
- Evening (only if you have cirrhosis): Toast with peanut butter and a glass of milk before bed.
- Drinks all day: Water, sparkling water, tea, coffee. No juice, no cola, and alcohol only within your limit or not at all.
This adds up to around 1,700 to 1,900 kcal with about 100 g of protein and very little added sugar. Scale portions up or down to your calculated needs.
Ray's kitchen, one year on
He still has a bacon sandwich on Sunday mornings. He has not touched cola since the diagnosis. He drinks four coffees a day and tells anyone who will listen that his consultant said it was medicinal, which is a slight exaggeration. He eats fish twice a week because his daughter buys it for him, walks every morning, and his FibroScan is normal. He lost 11 kg and has kept it off for eighteen months now, which is the part that matters.
If you are at the start of this, please do not buy the kale and the cleanse tea. Cut the sugary drinks, pour the olive oil, eat the fish, walk, lift something twice a week, drink the coffee, and if you have cirrhosis eat your protein and your bedtime snack. Your liver has been waiting to heal. This is how you let it.

Frequently asked questions
What is the best diet for fatty liver?
A Mediterranean pattern: olive oil, vegetables, legumes, whole grains, fish, nuts, with almost no sugary drinks or ultra processed food. It is the only diet with trial evidence of lowering liver fat independent of weight loss.
What foods should I avoid with liver disease?
Sugary drinks and juice first, then alcohol, ultra processed snacks, refined carbohydrates and processed meat. With cirrhosis, also limit salt and avoid raw shellfish.
Are eggs bad for the liver?
No. Eggs are a good source of protein and choline, which the liver needs to export fat. One or two a day fits comfortably in a liver friendly diet.
Is banana good for fatty liver?
Whole fruit, including bananas, is fine in normal amounts because its fibre slows the release of sugar. Fruit juice and smoothies are different and should be limited.
Should people with cirrhosis eat less protein?
No. That advice is outdated. Current guidelines recommend 1.2 to 1.5 g of protein per kg per day plus a bedtime snack to prevent muscle wasting, which is a major cause of poor outcomes in cirrhosis.
