Ketogenic Diet for the Treatment of Non-Alcoholic Fatty Liver Disease (NAFLD)
Article by the Keto doctors Dr. Brigitte Karner and Dr. Wolfgang Karner
Eating fat helps with fatty liver! Sounds paradoxical – but it’s true!
The ketogenic diet is an effective treatment method for non-alcoholic fatty liver disease. By reducing carbohydrates, liver fat decreases, insulin sensitivity improves, and inflammation is reduced. At the same time, metabolic syndrome and related conditions such as atherosclerosis, heart attack, stroke, and type 2 diabetes can be prevented or at least reduced.
After 3 months of a plant-based, healthy ketogenic diet, fatty liver is usually no longer detectable on ultrasound or has significantly improved.
30 years ago, when I was studying, a fatty liver was almost always the result of excessive alcohol consumption. Today, however, non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease worldwide. It is characterized by excessive fat accumulation in the liver without excessive alcohol intake as the cause. The condition is closely linked to metabolic syndrome and often occurs in people with obesity, type 2 diabetes, and insulin resistance.
In recent years, the ketogenic diet has increasingly been recognized as one of the most effective therapeutic strategies for managing NAFLD. This article highlights the benefits of the ketogenic diet for treating NAFLD, taking into account relevant scientific studies.
1. Causes of Non-Alcoholic Fatty Liver Disease
The development of NAFLD is generally caused by a combination of poor diet and lack of physical activity. One major cause is insulin resistance: cells reduce the number of insulin receptors to protect themselves from the consequences of excessive sugar concentrations inside the cell. In addition to increasing blood sugar and insulin levels, insulin resistance also leads to elevated glucose and fat accumulation in the liver.
Too much fruit and fruit juice promote fatty liver development
Excessive consumption of sugar—especially fructose—leads to abnormal fat storage in the liver and to an unfavorable distribution of different body fat types. Fructose in particular (as found in corn syrup, soft drinks, fruit juices, or smoothies) increases lipogenesis, meaning the conversion of sugar into fat, and therefore plays an important role in the development of obesity and NAFLD.
In addition to sugar and fructose, there is also evidence that certain gut bacteria may contribute to fatty liver development. A Chinese study published in 2019 identified a specific strain of Klebsiella pneumoniae capable of producing large amounts of alcohol (so-called fusel alcohols), which can damage the liver and lead to fatty liver—even without alcohol consumption. This study shows that, in addition to dietary habits, microbial factors such as the gut microbiome can play a role in the development of NAFLD.
2. Ketogenic Diet and Its Mechanism of Action
The ketogenic diet is a high-fat, very low-carbohydrate diet that forces the body to use fat instead of carbohydrates as its primary energy source. This happens through the production of ketone bodies in the liver, which serve as a fully adequate alternative energy source. The ketogenic diet has proven particularly effective for weight reduction and improving insulin sensitivity, which is highly significant for treating NAFLD.
An important mechanism through which the ketogenic diet works in NAFLD is the reduction of blood sugar and insulin levels, as well as the improvement of insulin sensitivity.
The plant-based ketogenic diet also normalizes the function of the beta cells in the pancreas and reduces fat storage not only in the liver but also in the pancreas. Through this mechanism, the ketogenic diet not only stops the progression of NAFLD but can also reverse existing liver damage.
3. Benefits of the Ketogenic Diet for Liver Health
In addition to reducing fat accumulation in the liver, the ketogenic diet offers a number of benefits that can positively influence liver health:
Improved lipid profiles A very low-carbohydrate diet such as the ketogenic diet leads to an improvement in lipid profiles by lowering triglyceride levels and improving the HDL-to-LDL cholesterol ratio. We regularly observe this in the lab results of our patients.
Weight loss One of the main advantages of the ketogenic diet in treating NAFLD is effective weight loss without the yo-yo effect, which is a key component in managing NAFLD. Overweight and obesity are strong risk factors for the development of NAFLD, and studies have shown that even moderate weight loss can significantly improve liver health.
Reduction of inflammation NAFLD is often associated with chronic inflammation of the liver. The ketogenic diet has anti-inflammatory properties that help reduce inflammation in the liver and slow the progression of the disease.
4. Connection with Metabolic Syndrome
NAFLD is closely linked to metabolic syndrome, a group of conditions that includes obesity, insulin resistance, high blood pressure, and dyslipidemia. Paschos et al. (2009) examined the connection between NAFLD and metabolic syndrome and found that NAFLD is often an early indicator of metabolic syndrome. A plant-based ketogenic diet can reverse fatty liver within a short period of time and prevent further related diseases.
Furthermore, a study by Catanzaro et al. (2016) showed that a ketogenic diet reduces the risk of non-alcoholic pancreatic fat accumulation (NAFPD), a lesser-known form of visceral fat deposition affecting the pancreas. Similar to fatty liver, excessive fat accumulation in the pancreas leads to insulin resistance and worsens metabolic syndrome.
The treatment of NAFLD, NAFPD, and metabolic syndrome through “food as medicine” should be supervised by physicians and nutritionists specifically trained in plant-based ketogenic nutrition. It is important to ensure that the diet is rich in micronutrients such as vitamins and minerals while also providing ample fiber to support overall health.
For some individuals, the ketogenic diet may cause side effects such as constipation, nausea, fatigue, and headaches, especially during the first weeks of transition. Close monitoring by an experienced ketogenic physician or nutritionist is therefore important to ensure that the diet is safe and effective.
Our patients with fatty liver have achieved impressive results with a ketogenic diet.
