Lifestyle overhaul tested as fatty liver fix
NCT ID NCT07652151
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
The UNMASK study is testing whether a 16-week program of Mediterranean diet and regular exercise can reduce liver fat and scarring in people with metabolic fatty liver disease (MASLD). Researchers will enroll 450 adults and track changes in liver health using scans and blood tests. The goal is to see if lifestyle changes alone can improve this common condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mediterranean diet plus structured exercise (150 min/week moderate or 75 min/week high-intensity)
- What this could lead to
- If successful, this could show that a simple lifestyle program can reduce liver fat and scarring in people with fatty liver disease, pointing toward a non-drug treatment option.
- What could go wrong
- This is an early-stage observational study with no control group, so results may not prove cause and effect. The lifestyle changes are intensive and may be hard for many to maintain long-term.
