Keto diet shows promise for stabilizing brain networks in mental illness

This study tested whether a 4-week ketogenic diet (very low carb, high fat) could improve brain network stability and thinking skills in 71 adults with schizophrenia or bipolar disorder. The diet aims to provide an alternative brain fuel (ketones) that may bypass problems with glucose metabolism common in these conditions. Participants were randomly assigned to either the keto diet or their usual diet, and researchers measured brain scans, body changes, inflammation, and insulin resistance.
