# Nutrition and diets in liver cirrhosis
What you eat and drink plays an important role in liver cirrhosis. The damaged liver can process certain substances less effectively, which means some dietary patterns can cause more problems than others. Research into nutrition in cirrhosis is ongoing; it is mainly about supporting the remaining liver function, preventing malnutrition and limiting complications.
Protein-rich nutrition
ResearchediPositive results in clinical studies, not yet standard treatment
In cirrhosis, the body typically needs more protein than normal, because the disease affects muscle mass. At the same time, this protein must be chosen carefully. This is mainly about good quality proteins — from fish, poultry, dairy products and plant-based sources such as legumes — instead of large amounts of red meat.
Recent guidelines (2026) emphasize that nutrition in cirrhosis must be 'tailored' and that adequate protein supply is essential for maintaining muscle mass. Studies show that muscle loss is an important risk factor for outcomes in cirrhosis; research into 'handgrip strength' and muscle volume helps doctors and dietitians determine whether protein intake is adequate. However, this goes far beyond just kilograms of protein — it is also about timing and form of nutrition (see also periodic fasting below).
For patients with hepatic encephalopathy (confusion due to accumulation of nitrogen-containing substances), a strict protein-restricted diet was long the standard, but this is now nuanced. The modern approach is rather: well-chosen proteins, instead of as little as possible.
Ketogenic diet
ExperimentaliOngoing in study setting, outcome still unknown
A ketogenic diet is one in which you eat a lot of fat and few carbohydrates, causing your body to enter 'ketosis' — a different energy process. In chronic liver disease, this has been little studied. Some preclinical studies suggest that changes in metabolism — including ketogenesis — may play a role in liver fibrosis and regeneration, but there is no research showing that a ketogenic dietary pattern benefits patients with cirrhosis.
Stronger still: people with cirrhosis often already have problems with their fat metabolism, and a very high-fat diet can in some cases mean unforeseen strain on the damaged liver. This diet is not recommended without approval and guidance from your healthcare provider.
Mediterranean dietary pattern
ResearchediPositive results in clinical studies, not yet standard treatment
The Mediterranean pattern — plenty of vegetables, fruit, whole grains, olive oil, fish and limited red meat — has in many studies been linked to better outcomes in liver disease, including in non-alcoholic fatty liver disease (MASLD) and the progression to fibrosis. The pattern contains many antioxidants and anti-inflammatory substances.
For cirrhosis specifically, direct evidence is less extensive, but the principles — good quality, plenty of vegetables, healthy fats — align with what modern guidelines (2026) recommend. It also helps that this dietary pattern is naturally low in salt (which is important in cirrhosis and fluid accumulation) and contains few processed substances.
Restriction of salt and fluid
ProveniIncluded in official guidelines, or approved by EMA or FDA
This is not a 'diet' in the strict sense, but an essential part of nutrition in cirrhosis. A damaged liver often cannot handle salt well, which can lead to fluid accumulation (ascites — abdominal fluid) and swollen legs. Many cirrhosis patients are therefore advised to significantly reduce salt intake.
The amount of fluid can also, especially if ascites is present, need to be limited. This is a classic measure and is in all guidelines. It requires attention in daily life — watch out for salt in ready-made products, processed meats, cheese and bread.
Periodic fasting and intermittent fasting
ExperimentaliOngoing in study setting, outcome still unknown
Intermittent fasting — eating within certain time windows and fasting in others — is being researched in many contexts for metabolic health. In liver cirrhosis, this has been little studied. Recent research (2026) shows that physical activity and changes in the gut microbiome (bacteria in your intestines) play a role in how well a cirrhosis patient does.
Some small studies suggest that certain forms of fasting and intermittent fasting can shift gut bacteria in ways that are potentially beneficial. At the same time: cirrhosis patients have increased nutritional needs and risk of malnutrition. Without supervision, fasting can be harmful. This is only considered under medical guidance, and certainly not for everyone.
Fluid content in drinks
ProveniIncluded in official guidelines, or approved by EMA or FDA
This is related to salt restriction, but is important separately. With ascites or other complications, the amount of fluid per day must sometimes be severely limited — not only water, but also milk, soup, fruit juice and other drinks count. This can feel very restrictive and requires clear agreements with your doctor.
Alcohol: avoid completely
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
This is not really a 'diet', but essential: completely alcohol-free. Alcohol is broken down in the liver and damages cells directly. With cirrhosis — however it arose — alcohol dramatically accelerates further liver damage and increases risk of complications and decompensation (deterioration). This applies to all alcoholic drinks, including beer and wine.
The reason is not caution, but likely: alcohol is poison for a damaged liver. This is universally advised against.
Certain additives and food supplements
ResearchediPositive results in clinical studies, not yet standard treatment
Recent research (2026) looks at ingredients that can slow or reduce fibrosis — for example morroniside (a plant compound) and certain minerals. At the same time, research warns against non-absorbable antibiotics, which in certain circumstances can actually be harmful to the gut microbiome and may worsen liver disease (2026).
These kinds of specific interventions are still in the research phase. They belong in the hands of your healthcare provider; taking supplements on your own can cause interactions with your medicines and is not safe.
Individualized care is essential
Nutrition in liver cirrhosis is not a standard matter. Whether you have ascites, how well your kidneys still work, whether you have hepatic encephalopathy, your medicines and your personal preferences — everything plays a role. A specialized dietitian, preferably one with experience in liver disease, can create a nutrition plan that fits your situation. Regular review and adjustments are normal.
