Summary

This study looked at whether eating only during an 8-10 hour daytime window (without cutting calories) could help immunotherapy work better in people with advanced head and neck cancer. 29 patients were asked to follow this eating pattern, and researchers tracked how well they stuck to it and how their gut bacteria changed. The goal was to see if this simple diet change could improve treatment outcomes.
