Summary

This study tests whether a 9-month lifestyle coaching program (individual and group sessions with a dietician) helps obese male firefighters lose weight and improve metabolic health. Fifty participants will be randomly assigned to coaching or usual care. The main outcomes are changes in body mass index, body fat, waist size, and waist-to-hip ratio.

What this could mean

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

Active substance: lifestyle coaching (individual and group sessions with a dietician)
What this could lead to: If it works, this could provide an effective weight-loss and health-improvement program tailored for firefighters.
What could go wrong: This is a small early-stage trial with only 50 participants, so results may not apply broadly. The intervention is behavioral, so success depends on individual adherence.
