First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a very low-carbohydrate ketogenic diet could improve brain network stability and thinking skills in people with schizophrenia or bipolar disorder. The diet is high in fat and low in carbs, which makes the body produce ketones that may provide extra energy to the brain. Seventy-one participants followed either the ketogenic diet or their usual diet for four weeks, and researchers measured changes in brain scans, body composition, inflammation, and insulin resistance.
