Could exercise reshape gut bacteria in fatty liver disease?
NCT ID NCT07697313
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This trial investigates whether high-intensity interval training or moderate continuous exercise, combined with a Mediterranean diet, can improve gut bacteria and metabolic health in people with non-alcoholic fatty liver disease. Participants are adults aged 40-60 with obesity and fatty liver who have not exercised regularly. The study measures changes in gut short-chain fatty acids, blood lipids, and quality of life over 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise training (high-intensity interval training or moderate intensity continuous training) plus Mediterranean diet
- What this could lead to
- If successful, this could show that a specific exercise program improves gut bacteria and metabolic health in people with fatty liver, offering a drug-free way to manage the condition.
- What could go wrong
- This is a small, early-stage trial with 60 participants, so results may not apply to everyone. The effects on gut microbiota are measured indirectly and may not translate to clear health benefits.
