Treatment of Moderate Hepatic Steatosis
For moderate hepatic steatosis, implement structured lifestyle modification targeting 7-10% sustained weight loss through Mediterranean dietary patterns and at least 150 minutes weekly of moderate-intensity exercise, as this represents the only intervention with Level 1 evidence for improving liver injury and inflammation. 1
Lifestyle Interventions: The Foundation of Treatment
Weight Loss Targets
The 2024 EASL-EASD-EASO guidelines establish clear, dose-dependent weight loss thresholds based on histological outcomes: 1
- 5% weight reduction: Reduces liver fat/steatosis 1, 2
- 7-10% weight reduction: Improves liver inflammation and can resolve steatohepatitis 1
- >10% weight reduction: Improves fibrosis 1, 2
For moderate steatosis, target 7-10% sustained weight loss to address both fat accumulation and inflammatory changes that define this stage. 1
Dietary Modifications
Adopt a Mediterranean dietary pattern as the primary nutritional approach, which has Level 2 evidence for improving liver injury: 1
- High intake of vegetables, fruits, low-fat dairy, nuts, olive oil, legumes, unprocessed fish and poultry 1, 3
- Completely eliminate sugar-sweetened beverages 1, 2
- Minimize processed meat and ultra-processed foods rich in sugars and saturated fat 1
- Unsweetened high-fiber cereals 4, 3
The evidence shows high saturated fat and simple sugars (particularly fructose) are risk factors for hepatic steatosis progression. 5
Exercise Prescription
Prescribe at least 150 minutes per week of moderate-intensity physical activity OR 75 minutes per week of vigorous-intensity activity, tailored to individual preference and ability. 1, 3
Physical activity reduces steatosis even without significant weight loss, making it essential even for normal-weight patients. 1, 4, 6
Risk Stratification and Monitoring
Before initiating treatment, stratify fibrosis risk using non-invasive testing: 2, 4
- Calculate FIB-4 score (incorporates age, AST, ALT, platelet count) 4, 3
- Low risk: FIB-4 <1.3 or LSM <8.0 kPa 4
- Intermediate risk: FIB-4 1.3-2.67 or LSM 8.0-12.0 kPa 4
- High risk: FIB-4 >2.67 or LSM >12.0 kPa (requires hepatology referral) 2, 4
Patients with high-risk scores or advanced fibrosis (F3) require hepatocellular carcinoma surveillance with imaging every 6 months. 2
Pharmacological Considerations
While lifestyle modification remains first-line, consider pharmacotherapy in specific contexts:
MASH-Targeted Therapy
Resmetirom should be considered for non-cirrhotic patients with significant liver fibrosis (stage ≥2) if approved locally, as it demonstrated histological efficacy in phase III trials with acceptable safety. 1, 2, 3
Cardiometabolic Medications with Hepatic Benefits
- GLP-1 receptor agonists (semaglutide, liraglutide) for patients with coexisting type 2 diabetes or obesity improve both cardiometabolic outcomes and liver histology 2, 3
- Statins are safe and should be used for dyslipidemia management in hepatic steatosis 2, 4
- SGLT2 inhibitors benefit patients with diabetes and hepatic steatosis 4
Medications to Avoid
Discontinue or avoid medications that worsen steatosis: corticosteroids, amiodarone, methotrexate, tamoxifen, estrogens, tetracyclines, and valproic acid. 2, 4
Multidisciplinary Management
A multidisciplinary approach is mandatory given the bidirectional connections between steatotic liver disease and cardiometabolic comorbidities. 1, 2, 3
Screen and Aggressively Manage:
- Type 2 diabetes (optimize glycemic control to reduce liver fat) 2, 4
- Dyslipidemia 2, 4
- Hypertension 2, 4
Special Considerations
Coffee Consumption
Coffee consumption has been associated with improvements in liver damage and reduced liver-related clinical outcomes in observational studies (Level 4 evidence). 1, 2
Bariatric Surgery
Consider bariatric surgery for appropriate individuals with clinically significant fibrosis and obesity with comorbidities (BMI >35 kg/m²), particularly when lifestyle modification has been insufficient. 2, 4, 3
Nutraceuticals
Nutraceuticals cannot be recommended due to insufficient evidence of effectiveness and safety. 1
Monitoring Treatment Response
Non-invasive tests may be repeatedly used to assess fibrosis progression, though they provide limited information about treatment response at the individual level. 1
Changes in non-invasive markers associated with resolution of steatohepatitis include: 1
Liver biopsy can be used to monitor disease progression or response to treatment in individual cases and clinical trials, but is not suited for routine clinical practice due to invasiveness. 1
