Summary

This study looks at whether exercising once a week or three times a week is better at reducing liver fat in adults who are centrally obese and have non-alcoholic fatty liver disease (NAFLD). Three hundred Chinese adults aged 18-69 will be assigned to either a once-weekly or thrice-weekly supervised treadmill program for 4 months. The goal is to find the most practical exercise frequency that still meets health recommendations and helps improve liver health.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
supervised treadmill exercise program
What this could lead to
If it works, this could show that even once-a-week exercise can meaningfully reduce liver fat, offering a practical option for busy people with NAFLD.
What could go wrong
This is a behavioral study with no blinding, so results may be influenced by participants' expectations. The effect may be modest and not apply to all NAFLD patients.
