Prevention and Management of Fatty Liver Disease (MASLD & MASH)
Fatty liver disease, now referred to as Metabolic Dysfunction–Associated Steatotic Liver Disease (MASLD) and its inflammatory form Metabolic Dysfunction–Associated Steatohepatitis (MASH), is a condition in which excess fat accumulates in the liver.
It is strongly associated with obesity, insulin resistance, type 2 diabetes, and cardiovascular risk factors. If left unmanaged, MASLD can progress to liver inflammation, fibrosis, cirrhosis, and in severe cases liver failure.
Prevention of Fatty Liver Disease
Eating high-fiber, lean foods help keep your metabolism steady and provides lasting energy. Here are the key foods to focus on:
Maintaining a healthy body weight
Engaging in regular physical activity
Limiting sugar-sweetened beverages and refined carbohydrates
Avoiding excessive intake of saturated fats and ultra-processed foods
Following a balanced dietary pattern rich in whole foods
Managing blood glucose, cholesterol, and blood pressure
Avoiding excessive alcohol intake
Management of MASLD and MASH
The primary goal of management is to reduce liver fat, improve insulin sensitivity, and prevent progression to liver inflammation or fibrosis.
Sustained lifestyle intervention is the most effective and evidence-based approach.
Dietary Approach: Core Strategy
Mediterranean-Style Eating Pattern
Vegetables and fruits
Whole grains such as oats, barley, brown rice, and quinoa
Legumes such as lentils, beans, and chickpeas
Nuts and seeds
Olive oil as the primary fat source
Fish, especially fatty fish rich in omega-3
Minimal intake of processed foods and added sugars
This dietary pattern improves insulin sensitivity and helps reduce fat accumulation in the liver.
High-Fiber Foods
Dietary fiber plays an important role in improving gut health, regulating blood sugar, and reducing liver fat accumulation.
Recommended high-fiber foods include:
Leafy green vegetables, broccoli, and cruciferous vegetables
Whole grains such as oats, barley, and quinoa
Legumes including lentils, beans, and chickpeas
Fruits such as apples, berries, and pears
Higher fiber intake is associated with improved metabolic and liver outcomes.
Healthy Fats
Healthy fats help reduce inflammation and support metabolic balance.
Include:
Olive oil (extra virgin preferred)
Avocados
Nuts such as almonds and walnuts
Seeds such as flaxseed and chia seeds
Fatty fish such as salmon, sardines, and trout
Foods to Limit
Certain foods contribute to liver fat accumulation and disease progression and should be minimized:
Sugar-sweetened beverages and fruit juices
Refined carbohydrates such as white bread and pastries
Deep-fried and fast foods
Processed meats
High-sugar desserts and sweets
Excess red meat intake
Lifestyle Management
Along with diet, lifestyle modification is essential:
Regular physical activity improves liver fat and insulin resistance
Weight reduction in overweight individuals significantly improves liver outcomes
Adequate sleep supports metabolic regulation
Avoiding sedentary behaviour reduces risk progression
Even modest weight loss can improve liver fat content and inflammation.
Key Message
MASLD and MASH are reversible in early stages through sustained lifestyle changes. A Mediterranean-style dietary pattern, rich in fiber, whole foods, and healthy fats, combined with physical activity and weight management, remains the cornerstone of prevention and treatment.
