Could a keto diet boost brain zaps for depression?

This study tests whether adding a ketogenic (low-carb) diet to a non-invasive brain stimulation treatment called iTBS helps people with treatment-resistant depression feel better. Sixty adults will follow either a keto diet or a standard healthy diet for three weeks, then receive personalized brain stimulation while staying on their diet. Researchers will measure changes in depression scores, ketone levels, and brain scans to see if the combination is safe and effective.
