If your liver is healthy, a well-balanced diet can reduce your risk of developing some types of liver disease in the future. If you have liver disease, eating a good, balanced diet is essential to maintain strength and a healthy weight.
You might also need to change the food you eat depending on:
- the type of liver disease you have
- the stage of the damage to your liver
- any eating difficulties you experience, such as loss of appetite or feeling sick

Your liver and the food you eat
You need food to power your body, giving it energy and the material it needs to grow and repair itself. When you eat food, it is broken down in your stomach and intestine (gut) and three main nutrients are extracted:
- carbohydrates
- fat
- protein
These nutrients are then absorbed into the bloodstream and carried to your liver. Here they are either stored, or changed in such a way that your body can use them at once.
At the same time your liver is also working to detoxify substances which may harm your body such as alcohol, other drugs and some of your body’s waste products. If you have a liver problem, then your liver may not be able to do these jobs as efficiently as it should.
A well-balanced diet
You need to get the right balance between different foods and drinks to help your body work properly and be healthy. The evidence shows that for most people a well-balanced diet is the best way to stay healthy and manage your weight.
A healthy, balanced diet is a way of thinking about everything you eat and drink. The overall picture of your diet is more important than any one small detail. The aim is to generally eat and drink healthily most of the time. You can adapt it to suit you, for example if you are vegetarian.
For most people, a well-balanced diet is one that is low in fat, sugar and salt, and high in fibre, vegetables and fruit. Your diet should also contain enough protein and a wide range of vitamins and minerals.

It is important to remember that your body’s nutritional needs may vary depending on the type and severity of your condition.
Keeping a healthy weight
Some liver diseases are linked to build up of fat in the liver. This leads to a condition called metabolic dysfunction-associated steatotic liver disease. If fatty deposits build up over a long time they can damage the liver and stop it working properly. People are more likely to develop MASLD if they have an unhealthy diet or they live with overweight or obesity.
Obesity can also speed the damage associated with other conditions such as alcoholic liver disease and can decrease the effectiveness of treatments for hepatitis C .
It is important to maintain a healthy weight. To do this you need to balance the amount of food you eat with the energy you need. If you eat more than you use, your weight will increase. If you eat fewer calories than your body uses you will lose weight. There are two ways to shift the balance of calories and lose weight. Eat a healthy, balanced diet. And be more physically active.
Losing weight can seem hard. Take it one step at a time and keep going. People often find it is easier to make small changes one at a time. Give yourself time to get used to your change and then make another one.
Staying nutritionally well
If you have a liver condition, there are some special considerations you may need to make in your diet to stay nutritionally well and to help to manage your condition. Some of these are specific to certain liver diseases, others relate to how advanced your liver disease is.
If you are experiencing symptoms such as loss of appetite, nausea, low energy levels, fluid retention in the legs or accumulation of fluid in the abdomen (ascites), you will need to follow a more specialised diet. These, and other problems associated with advanced liver disease, require specialist dietary advice from a registered dietitian.
It is important that you talk to your doctor as well as reading this information. Your consultant will be able to refer you to a registered dietitian. If you have already been given dietary advice you should not make changes without first talking to your consultant or dietitian.
Cirrhosis / advanced liver disease
If you have cirrhosis you may be advised to consume more energy (calories) and protein than a healthy person of the same weight and age.
If you haven’t seen a dietitian or you have specific questions about your diet, ask you doctor to refer you.
Coping with eating difficulties
Some people find eating a well-balanced diet difficult, especially if they have been seriously ill.
However, it is important to eat as well as possible. Follow the link below for some tips.
Complementary and alternative medicines
There is a great deal of information available about complementary and alternative medicines on the internet.
If you have liver disease, it is important to seek advice from your doctor before taking any complementary medicines or dietary supplements.
FAQs
What is a 'fad' diet and are they safe?
Fad diets are usually weight loss diets that promise you can lose weight quickly. These diets usually involve crash dieting; calorie intakes may be drastically reduced or certain food groups such as carbohydrates removed almost entirely. These diets tend to provide a short-term fix but are difficult and potentially dangerous to maintain in the longer term. They are generally not recommended for people with liver disease.
I have read about diets which ‘detox’ your liver – should I try one?
There are diets that recommend certain foods to help your liver ‘detox’ or promote ‘liver cleansing’. However, you cannot physically detox your liver. There is no evidence that toxins build up in the liver and some of these diets can be dangerous for people with liver disease.
Should I take dietary supplements?
Dietary supplements are not an alternative to eating a well-balanced diet. Your body needs a wide range of vitamins and minerals to be able to function correctly, and the best way to ensure an adequate supply of these is to eat a variety of foods. You should always consult your doctor or dietitian before considering taking supplements. If you are prescribed supplements, you should always take them.
Can I take complementary and alternative medicines?
A great deal of information is available online and in the media about complementary and alternative treatments for liver disease. It is important to seek advice from your doctor before considering use of these products. Many are based on herbal preparations which may themselves cause liver damage in susceptible people, so at present healthcare professionals do not believe that they have a place in the management of people with liver disease. More research is needed on the use of such therapies.
As the majority of these products are not classified as medicines they are not licensed. This means that their production is not controlled and there is no requirement for them to undergo rigorous testing for quality or effectiveness.
It is possible that these often-expensive products may either have no effect or even be harmful.
Does milk thistle help the symptoms of liver disease?
Milk thistle is an over-the-counter supplement which is advertised as a natural treatment for jaundice, hepatitis, cirrhosis and gallbladder disease. The active ingredient of milk thistle is silymarin, which is believed to have antioxidant properties.
The evidence that milk thistle is an effective treatment for liver disease is conflicting, with no strong evidence to support its use. In addition, it could result in low blood sugar levels.
It might also interfere with the actions of drugs such as diazepam (sedative), warfarin (anticoagulant) and metronidazole (antibiotic). Of particular concern, milk thistle might change the way the body processes sirolimus, an immunosuppressant used following liver transplantation.
Do not use milk thistle without discussing it with your doctor.
I do not have alcohol-related liver disease so can I drink alcohol?
People with alcohol-related liver disease should stop drinking alcohol for life.
If your liver disease is not alcohol-related, and you are concerned about whether you can drink alcohol, discuss it with your doctor. If your doctor says you can drink alcohol, stick to government guidelines and drink no more than 14 units a week, with 2-3 consecutive alcohol-free days each week. However, the lower your alcohol intake the better.
Remember that alcohol is a significant source of calories. For example, a 330ml can of 5% beer contains around 129 calories and a 175ml glass of wine (12%) has about 158 calories (for comparison, a Cadbury Mini Roll contains 115 calories and a 330ml can of Coca-Cola contains 139 calories). These are ‘empty calories’ and can cause unhealthy weight gain.
Alcohol can worsen the liver damage caused by chronic viral hepatitis, obesity-related liver disease and haemochromatosis. It can also increase the risk of bone disease and may interfere with a number of commonly prescribed medications.
