Fatty liver disease linked to metabolic dysfunction is now usually called MASLD. The outcome worth chasing is less liver fat, lower inflammation and fibrosis risk, and better control of the diabetes, weight, lipids, blood pressure, and alcohol exposure that shape long-term liver and heart health. A lower enzyme on one test is a small part of that.
Most people with early MASLD can improve it substantially. The first clinical priority is finding out who already has significant fibrosis, because fibrosis, more than the amount of fat, is the strongest liver-related risk marker. Simple blood-based scores and elastography can help. A normal ALT does not reliably rule fibrosis out.
What to do
- Lose weight at a pace you can keep if excess weight is a driver. Even modest loss can reduce liver fat; larger, maintained losses are more likely to improve inflammation and fibrosis. The right amount and method are individual.
- Pick a food pattern you can stay on. A Mediterranean-style pattern rich in vegetables, legumes, whole grains, fish, nuts, and unsaturated oils is a sound default. Cut sugary drinks, excess refined carbohydrate, and the ultra-processed foods you eat on repeat.
- Move every week. Aerobic and resistance exercise can reduce liver fat even without major weight loss. Start where you are and build toward regular moderate activity plus two strength sessions.
- Be honest about alcohol. MASLD can coexist with alcohol-related injury. The safest amount depends on liver status and other risks; advanced fibrosis or cirrhosis usually calls for abstinence.
- Treat diabetes, lipids, and blood pressure. Cardiovascular disease is a major risk for people with MASLD. Evidence-based metabolic treatment is part of liver care.
- Review medicines and other liver causes. Viral hepatitis, autoimmune disease, iron overload, and some medicines can cause or worsen abnormal liver findings. Don’t assume all the fat or enzyme elevation has one cause.
- Use disease-directed care when eligible. Some people with more advanced inflammatory disease qualify for medication or specialist care, depending on confirmed stage and current approvals.
A simple plan
Start from the diagnosis and risk stage you actually have: imaging, ALT and AST, platelet count, diabetes status, lipids, blood pressure, alcohol pattern, weight trend, and any fibrosis score or elastography. Ask whether you need hepatology follow-up.
For 12 weeks, run a plan you can repeat: replace sugary drinks, cook two plant-forward dinners a week, walk briskly for 30 minutes on five days, and strength train twice. If weight loss is appropriate, aim for a steady trend, not a crash. Set a clear alcohol limit.
Schedule reassessment around the marker that can answer the question: metabolic labs and weight sooner, liver imaging or fibrosis assessment at a clinically meaningful interval.
