The most effective treatment for fatty liver disease (NAFLD) is lifestyle modification focusing on diet and exercise, aiming for gradual sustained weight loss, especially in overweight or obese individuals. A target weight loss of 5-10% over 6 months with a calorie deficit of approximately 600 kcal/day is recommended. Combining aerobic exercise with dietary changes, such as adopting a Mediterranean diet, is the most effective approach to reduce liver fat and improve liver health. Moderate intensity exercise totaling 150-200 minutes per week in 3-5 sessions is advised. Alcohol consumption should be kept within national recommended limits to reduce liver disease risk. Management of associated metabolic conditions like hypertension, hyperlipidaemia, and type 2 diabetes is also important. Currently, no specific drug treatment is licensed for NAFLD in primary care, but in secondary or tertiary care, off-label use of pioglitazone or vitamin E may be considered for adults with advanced liver fibrosis. Bariatric surgery is an option for eligible patients and has shown significant resolution of steatosis and fibrosis. Statins are safe and beneficial for people with NAFLD who require them for cardiovascular risk management and may improve liver histology.
