Summary

This study looks at whether a ketogenic (high-fat, low-carb) diet is practical and beneficial for 24 adults with brain metastases who are scheduled for radiosurgery. Participants will follow either a ketogenic diet or a standard healthy diet for 16 weeks. Researchers will track diet adherence, blood markers, and quality of life to see if the diet helps manage symptoms and improve well-being.
