Summary

This study looked at whether a nutrition and behavior change program could help reduce sleep apnea in people who are overweight or obese. About 400 adults took part, and researchers measured changes in sleep apnea risk, daytime sleepiness, and weight loss. The goal was to see if this approach works as well as surgery for improving sleep apnea.
