Summary

This completed study compared moderate exercise (like brisk walking) with the drug metformin in 226 adults with prediabetes. Participants were randomly assigned to either exercise for 30-45 minutes, 5 days a week, or take metformin twice daily for 12 weeks. Researchers measured changes in blood sugar (HbA1c) and weight to see which approach worked better in a real-world, low-resource community setting.

What this could mean

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

Active substance
metformin
What this could lead to
If it works, this could show that exercise is as good as or better than metformin for controlling blood sugar in prediabetes, offering a low-cost option.
What could go wrong
This is a small, completed trial in one community, so results may not apply broadly. Also, open-label design means participants knew their group, which can bias results.
