Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease characterised by the accumulation of fat in the liver. NAFLD can be caused by excessive alcohol use or other factors unrelated to alcohol. A ketogenic diet can be used to treat NAFLD by reducing fat and reversing the condition. The ketogenic diet involves a very low carbohydrate intake, typically between 5-10% of total calories for the day. This diet can decrease insulin levels, reduce lipogenesis and increase the rate at which fatty acids are broken down. Research has shown that the ketogenic diet can improve blood sugar parameters, reduce cardiovascular risk factors and improve liver health.

What You'll Learn

- Ketogenic diets can reduce oxidative stress and inflammation in the liver
- Ketogenic diets can suppress appetite, promote weight loss, and improve heart health markers

- Ketogenic diets can reduce liver fat and protect the liver from further injury
Ketogenic diets can reduce insulin levels and lipogenesis, and increase the rate at which fatty acids are broken down
Ketogenic diets can help to reduce insulin levels and lipogenesis, and increase the rate at which fatty acids are broken down. This is because ketogenic diets are very low in carbohydrates, typically between 5-10% of total calories for the day. This reduction in carbohydrates decreases insulin levels, which in turn reduces lipogenesis, the process of converting carbohydrates into fatty acids. Ketogenic diets also increase the rate at which fatty acids are broken down, or their oxidation rate, which can help to reduce oxidative stress and inflammation in the liver.
Ketogenic diets have been shown to be effective in reducing insulin levels and improving cholesterol numbers, in addition to aiding weight loss. A 2018 study found that a ketogenic diet improved blood sugar parameters, reduced cardiovascular risk factors, and reduced the need for medications to manage high blood pressure and diabetes in obese or overweight patients. Another study found that a ketogenic diet led to a significant weight loss, as well as improvements in liver steatosis, fibrosis, and inflammation as shown in liver biopsies.
The ketogenic diet can also help to increase satiety, which can lead to a reduction in portion sizes and facilitate weight loss. Additionally, ketogenic diets can help to reduce abdominal fat and the risk for metabolic syndrome.

Ketogenic diets can reduce oxidative stress and inflammation in the liver
Ketogenic diets have been shown to be effective in reducing liver fat and protecting the liver from further injury. They can also help prevent fatty liver disease and reverse fatty liver damage.
- Lowering insulin levels and lipogenesis
- Increasing the rate at which fatty acids are broken down (or their oxidation rate)
- Reducing oxidative stress, which helps reduce inflammation and irritation in the liver
- Lowering blood sugar and improving insulin sensitivity
- Increasing satiety, which leads to eating smaller portions without feeling hungry
- Reducing abdominal fat and the risk for metabolic syndrome
- Lowering triglyceride levels

Ketogenic diets can suppress appetite, promote weight loss, and improve heart health markers
Ketogenic diets have been shown to suppress appetite, promote weight loss, and improve heart health markers.
Ketogenic diets have been shown to suppress appetite and promote weight loss in several studies, including a meta-analysis of randomised controlled trials, which is considered the strongest, highest-quality evidence. In several trials, people with non-alcoholic fatty liver disease (NAFLD) who followed a keto or low-carb diet ended up eating less and losing abdominal fat without intentionally restricting calories.
Ketogenic diets have also been shown to improve heart health markers. Other benefits of low-carb eating include reductions in heart disease risk factors, such as lower blood triglycerides, blood sugar, and blood pressure.

Ketogenic diets can reduce the need for medications to manage high blood pressure and diabetes
A ketogenic diet can help reduce the need for medications to manage high blood pressure and diabetes.
Ketogenic diets can help to reduce the need for medications to manage high blood pressure and diabetes. This is because they can help to lower blood pressure and improve cholesterol numbers (by lowering triglycerides and increasing HDL). They can also help to reduce blood sugar and improve insulin sensitivity. This is important because insulin resistance is a key abnormality in non-alcoholic fatty liver disease (NAFLD).
A 2018 study evaluated the effects of a ketogenic diet in 262 obese or overweight patients. After one year, participants had improved their blood sugar parameters, reduced their cardiovascular risk factors, and reduced the need for medications to manage high blood pressure and diabetes.
A 2020 meta-analysis of 154 articles reviewed the benefits of the keto diet on NAFLD. The authors concluded that, in addition to caloric restriction, macronutrient distribution also plays a role in NAFLD treatment. They found that high-fat keto diets had a greater and faster impact on liver fat content than only restricting carbohydrates. The meta-analysis also noted the role ketosis plays in liver fat reduction due to fatty acid oxidation.

Ketogenic diets can reduce liver fat and protect the liver from further injury
Ketogenic diets have been shown to be effective in reducing liver fat and protecting the liver from further injury. Non-alcoholic fatty liver disease (NAFLD) is a condition where there is an excessive amount of fat stored in the liver. This can lead to inflammation and dysfunction, and in some cases, progress to a more serious condition called non-alcoholic steatohepatitis (NASH).
Ketogenic diets, which are very low in carbohydrates and high in fats, have been found to decrease liver fat and improve liver function. This is because ketogenic diets can lower insulin levels, which in turn reduces lipogenesis (the process of converting carbohydrates into fatty acids) and increases the rate at which fatty acids are broken down. Additionally, ketogenic diets can suppress appetite, promote weight loss, and improve heart health markers.
Research has shown that a ketogenic diet can improve blood sugar parameters, reduce cardiovascular risk factors, and decrease the need for medications to manage high blood pressure and diabetes. In one study, participants who followed a ketogenic diet had improved liver enzyme levels, sustained weight loss, and a reduction in the diabetes lab test HbA1c.
Ketogenic diets may also offer protection against liver injury. A study found that the ketone molecule beta-hydroxybutyrate (BHB) reduced hepatic steatosis, total liver triglyceride, and plasma ALT, which is a liver enzyme used to measure liver health. BHB has also been found to have anti-inflammatory effects, which can help reduce liver inflammation and injury.
Overall, ketogenic diets have been shown to be a promising approach to reducing liver fat and protecting the liver from further injury, especially in those with NAFLD.

Frequently asked questions
Fatty liver disease is a condition where fat accumulates in the liver, causing inflammation and dysfunction. There are two types: alcoholic fatty liver disease (caused by excess alcohol use) and nonalcoholic fatty liver disease (NAFLD, caused by many factors unrelated to alcohol).
Risk factors for NAFLD include being overweight or obese, having high triglyceride levels, and having metabolic syndrome. Other factors include being middle-aged or older, and being of Hispanic or non-Hispanic white ethnicity.
Fatty liver disease often shows no early symptoms, so it's important to detect it early through routine full-body scans. Lab tests can also help identify fatty liver disease, but only after damage to liver health and function has begun.
Alcoholic fatty liver disease can often be reversed by reducing or stopping alcohol use. Weight loss is the most common treatment recommendation for NAFLD, as it can reduce the amount of fat in the liver, lower inflammation, and reduce scarring.
The keto diet can help prevent and reverse fatty liver damage. It can reduce lipogenesis (the process of converting carbohydrates into fatty acids), increase the rate at which fatty acids are broken down, and reduce oxidative stress, which helps reduce inflammation and irritation in the liver. The keto diet can also help with weight loss and improve insulin levels.
