Summary

This study tested whether personalized diet advice based on a person's gut bacteria could improve food choices and gut health in 50 adults with obesity in Colombia. Participants either got tailored diet recommendations or standard advice for 12 weeks. Researchers measured changes in gut bacteria diversity, blood sugar, cholesterol, and weight.

What this could mean

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

Active substance: personalized dietary recommendations based on gut microbiome testing
What this could lead to: If successful, this approach could offer a practical, non-drug way to improve diet and gut health in people with obesity.
What could go wrong: This is a small, completed trial with only 50 participants, so results may not apply to larger or different populations. Dietary changes can be hard to maintain long-term.
