Dietary Patterns for Management of Obesity and Non-alcoholic Fatty Liver Disease

Reviewed by: Dr. T S Deepthi Sarojini | Author: Manoja Kalakanti

You are enjoying a delicious meal with your friends, feeling content and satisfied. But did you know what you are eating could impact more than just your taste buds? That is right – the food we consume can significantly impact our liver health, particularly regarding non-alcoholic fatty liver disease (NAFLD).

NAFLD is a condition in which too much fat accumulates in the liver, causing inflammation and possibly liver damage. And what is one of the essential NAFLD risk factors? Obesity. That is why it is crucial to comprehend the relationship between obesity and NAFLD and how to take proactive steps toward preventing and managing these health issues. We will discuss what is fatty liver disease, the stages and progression of NAFLD, and treatment, and how lifestyle changes, such as healthy eating habits and regular exercise, can reduce the risk of developing NAFLD and promote overall liver function.

How Are Obesity and Non-alcoholic Fatty Liver Disease Correlated?

Non-alcoholic fatty liver disease (NAFLD) is when the liver accumulates excess fat. It is strongly linked to obesity, with up to 90% of obese people suffering from some form of fatty liver disease. This is due to a lipid metabolism imbalance caused by excess body fat, which overloads the liver with fatty acids, resulting in inflammation, oxidative stress, and liver damage.

NAFLD is a progressive disease that can lead to more severe liver damage and even liver cancer. Therefore, understanding the link between obesity and NAFLD is critical for preventing and managing this disease. Now we will look into the stages of liver damage, NAFLD’s symptoms, causes, and treatments providing valuable information to help manage and prevent this condition.

The Grades of Non-Alcoholic Fatty Liver Disease

NAFLD, or Non-Alcoholic Fatty Liver Disease, is divided into four stages based on the severity of liver damage and inflammation. They are as follows:

Grade 1 or Simple Steatosis

Fat accumulates in the liver cells (hepatocytes) in Grade 1 or Simple Steatosis, but there is little or no inflammation or damage of liver cells.
This stage of NAFLD is generally considered harmless and frequently reversible through lifestyle changes such as weight loss and exercise.
However, some people with simple steatosis may progress to more severe stages of NAFLD, especially if they have other risk factors.

Grade 2 or Non-alcoholic Steatohepatitis (NASH)

There is inflammation and liver cell damage in addition to fat accumulation.
If left untreated, NASH is a more severe stage of Non-Alcoholic Fatty Liver Disease that can result in liver scarring or fibrosis.
NASH patients are more likely to develop liver cancer or cirrhosis.

Grade 3 or Fibrosis

Fibrosis is the accumulation of scar tissue in the liver, which can lead to decreased liver function.
Symptoms of this stage of NAFLD include fatigue, abdominal pain, and swelling in the legs or abdomen.
If left untreated, fibrosis can progress to cirrhosis or liver failure.

Grade 4 or Cirrhosis

Cirrhosis is a severe form of liver scarring and damage that can result in liver failure, cancer, or the need for a liver transplant.
Cirrhosis patients may experience skin and eye yellowing, confusion, and abdominal swelling.
Cirrhosis treatment may include lifestyle changes, medication to manage symptoms, or, in severe cases, a liver transplant.

The Science of Non-alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease is a complex condition with numerous symptoms and potential causes, making it a hot topic among scientists and medical professionals. Therefore, understanding the science of NAFLD is critical for developing effective treatments and prevention strategies.

Symptoms of Non-alcoholic fatty liver disease

Initially, there may be no symptoms, but as the condition progresses, the following fatty liver disease symptoms may appear:

Fatigue
Abdominal discomfort or pain
Jaundice (yellowing of the skin and eyes)
Enlarged liver
Elevated liver enzymes in blood tests
Spider-like blood vessels on the skin
Swelling in the legs or abdomen
Mental confusion or difficulty concentrating
It is important to note that some people with NAFLD may not show symptoms, so regular check-ups and liver function tests are advised for those at risk.

Causes of Non-alcoholic Fatty Liver Disease

The causes of fatty liver disease are multifactorial and complex. Here are some factors that can contribute to the development of NAFLD:

Obesity or overweight
Insulin resistance and metabolic syndrome
Type 2 diabetes
High blood pressure
High levels of triglycerides in the blood
Sedentary lifestyle
Poor diet, especially a high intake of sugar and saturated fats
Rapid weight loss or malnutrition
Genetic factors and family history

These are a few conditions that cause fatty liver disease, but it is essential to note that not everyone with these risk factors will develop NAFLD, and some people with no known risk factors may develop the condition.

Treatments for Non-alcoholic Fatty Liver Disease

There are no specific medications or fatty liver disease treatments. Instead, your doctor will most likely advise you to make several significant lifestyle changes. These are some examples:

Lifestyle changes

Changes in lifestyle, such as eating a healthy, balanced diet and increasing physical activity, can help people with obesity and NAFLD lose weight and improve liver function. Avoiding alcohol and limiting sugar and saturated fat intake can also help improve liver health.

Management of comorbidities

Treating comorbidities like diabetes and high cholesterol with medications and lifestyle changes can reduce the risk of non-alcoholic fatty liver disease progression and improve overall health. In addition, regular monitoring and follow-up with a healthcare provider are critical for managing comorbidities and preventing NAFLD complications in obese people.

Bariatric surgery

Bariatric surgery, well known for weight loss surgery, may be recommended by specialists for people with obesity and NAFLD who have failed to lose weight using other methods. It can lead to substantial weight loss and enhanced liver function in people with NAFLD. Consult a specialist to know whether you are suitable for the surgery.

Weight loss

One of the most efficient ways to lower liver fat and improve liver function in people with obesity and NAFLD is to lose weight through a fatty liver disease diet and exercise. Studies have shown that a weight loss of 7-10% of body weight can significantly improve liver health in people with NAFLD.

Diet Plan for managing Obesity and Non-alcoholic Fatty Liver Disease

Bottom Line

Obesity and non-alcoholic fatty liver disease (NAFLD) are complex health problems linked to various factors, including dietary patterns. The good news is that diet can be essential in treating obesity and NAFLD. In addition, weight loss through diet and exercise, bariatric surgery, medications, and lifestyle changes can all help to improve liver health and lower the risk of NAFLD complications. Individuals with obesity and NAFLD can improve their liver health and overall well-being with proper management and lifestyle changes. Working with a healthcare provider is essential for developing a personalized treatment plan and ensuring proper monitoring and follow-up.
