Fish oil and exercise: a One-Two punch against obesity inflammation?
NCT ID NCT05295719
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at whether taking fish oil and doing high-intensity interval training (HIIT) could lower inflammation in people who are overweight or obese. Researchers measured changes in blood markers of inflammation and metabolism over 10 weeks. The goal was to see if the combination works better than either alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance

- What this could lead to
- If it works, this could point toward a simple way to lower inflammation and improve metabolic health in people with obesity.
- What could go wrong
- This is a small, early-stage study with only 129 participants. The results may not apply to everyone, and the effects might be modest or short-lived.
