The liver is arguably your most hard-working and versatile organ. Most people associate the liver with detoxification, but it also involves metabolism, immunity, digestion, and vitamin storage.1 When the liver becomes damaged through a condition called Non-Alcoholic Fatty Liver Disease (NAFLD) and is unable to function normally, there are major negative rippling effects throughout the body. 

NAFLD is the most common cause of liver transplants, estimated to affect 30% of people in the United States.2 Several genetic, hormonal, and socioeconomic risk factors increase the risk of NAFLD, but it’s most closely associated with metabolic syndrome. 

Metabolic syndrome is a group of conditions (high blood pressure, high triglycerides, low HDL cholesterol, high blood sugar, and excess abdominal fat) that raise your risk of heart disease, diabetes, stroke, and NAFLD.4,5 The good news is proper nutrition and other lifestyle changes can help manage and even reverse non-alcoholic fatty liver.

Non-Alcoholic Fatty Liver: What Does It Mean?

As its name describes, a fatty liver is the build-up of triglycerides and other fats within the cells of the liver.3 Due to various causes, liver cells ( hepatocytes) can accumulate fat droplets. NAFLD is diagnosed when more than 5% of hepatocytes contain fat. 

This abnormal collection of fat in the liver, known as hepatic steatosis, can progress to a more serious condition called non-alcoholic steatohepatitis (NASH). NASH occurs when there is a build-up of fat and subsequent liver inflammation, which damages the hepatocytes. NASH is a serious condition that can lead to cirrhosis, liver failure, and liver cancer.5 

Here are the most common signs and symptoms of fatty liver:

  • Abdominal pain
  • Nausea
  • Swelling of the legs (edema)
  • Yellowing of the skin and eyes (jaundice)
  • Fatigue and weakness6

Main Causes of Non-Alcoholic Fatty Liver Disease

NAFLD can be caused by a combination of factors including insulin resistance, hormones, nutrition, gut microbiota, genetics, and epigenetics.7 The risk of NAFLD increases when you have any of the following conditions:

Obesity

Overweight and obesity are the primary drivers of NAFLD. It’s believed that your adipose tissues have a finite amount of storage, and when that’s reached, fat begins to be stored in your liver.8  

Metabolic syndrome

This cluster of conditions (abdominal obesity, high blood sugar, abnormal triglycerides and cholesterol, and high blood pressure) significantly increases the risk of NAFLD.8 

Type 2 diabetes

NAFLD is common in people living with type 2 diabetes. In fact, a meta-analysis looking at 24 studies and more than 35,000 patients revealed that almost 60% of patients with T2D and NAFLD.9 

Insulin resistance

Insulin resistance contributes to NAFLD by increasing lipogenesis (creation of fats) and decreasing fatty acid oxidation (the breakdown of fats).10

High cholesterol

The liver plays a primary role in regulating cholesterol in the body. A buildup of excess cholesterol can cause liver damage, leading to NAFLD.

Thyroid problems

Your thyroid is directly involved in metabolism. An underactive thyroid can lead to being overweight and obesity, which increases your risk of NAFLD. 

Hepatitis C

Hepatitis C is a virus that attacks the liver and can cause hepatic inflammation. One study found that 47% of patients with Hep C had fatty liver.11

Can Fatty Liver Be Reversed? How to Do It 

Fatty liver is directly associated with obesity and metabolic syndrome. Fortunately, there are many lifestyle changes you can make to reduce your risk and even reverse these conditions. Talk to your doctor about the lifestyle and behavior changes that may be right for you. 

Here are healthy changes you can make today to manage and improve fatty liver disease:

Weight loss

If you’re overweight, focus on shedding those excess pounds. Being at an optimal body weight can significantly improve the health of your liver. 

Optimize your diet

Eating in a way that supports a healthy metabolism can optimize liver functioning. It’s been shown that diets high in saturated fat, high in carbohydrates, and low in fiber are associated with NAFLD. Additionally, diets high in sucrose and fructose have been found to lead to fatty liver.2 Aim for a diet rich in colorful whole plant foods and healthy protein. Avoid processed foods and alcohol. 

Exercise

Regardless of weight loss, exercise can reduce liver fat and reverse fatty liver disease. Exercise recommendations for fatty liver disease don’t indicate a specific type or amount, but it’s clear that physical inactivity is associated with increased severity of liver disease.12 

Sleep 

Poor sleep and unhealthy sleep habits like late bedtimes, snoring, and long daytime naps significantly increase your risk of developing fatty liver disease. The good news is moderate improvements in sleep quality can reduce your risk by almost 30%.13

Best Diet for Fatty Liver Disease 

If you have fatty liver disease, you should focus on a diet that supports weight loss, reduces insulin resistance, and optimizes cholesterol and triglyceride levels. Here are some nutrition guidelines to follow:

Increase your fruit and vegetable intake

Focus on fruits that are low in sugar, like berries, and vegetables that are low in carbohydrates, like leafy greens.

Eat fish 1-2 times per week

Small wild caught fish can provide the healthy fats and protein you need.

Increase your fiber intake

Fiber not only supports weight loss but also helps improve cholesterol levels.

Limit your carbohydrate intake

Diets high in carbs increase your blood sugar, which increases insulin and can lead to insulin resistance.

Avoid processed foods

Packaged foods are much higher in sugar and salt than whole foods, and they also contain additives that can interfere with your metabolism. 

Supplements For Fatty Liver Disease 

While clinical research is limited, some supplements may be helpful in improving fatty liver disease. Work with your healthcare practitioner to see if any of the following may be right for you.

  • Silymarin - Also known as milk thistle, this supplement can reduce insulin resistance, reduce hepatic inflammation, and reduce fibrosis.14
  • Vitamin E - This antioxidant has also been shown to reduce inflammation in the liver and prevent fibrosis.14
  • Vitamin D - This vitamin can not only improve insulin sensitivity, it has also been shown to reduce inflammation in the liver and throughout the body.14
  • Omega 3 -  Omega 3 supplements may help reduce overall inflammation and optimize liver enzymes.14

When You Should Reach Out to a Professional

If you've been diagnosed with fatty liver disease, it’s important that you talk to your doctor about warning signs that the disease is getting worse. 

Contact your healthcare provider if you experience any of the following:

  • Fatigue or weakness
  • Loss of appetite 
  • Weight loss
  • Fluid retention
