In plain English

In adults with schizophrenia or bipolar disorder and metabolic issues, following a ketogenic diet for four months is linked to a 17% higher self-reported life satisfaction and a 19% better sleep quality.

See the scientific wording

In adults with schizophrenia or bipolar disorder and metabolic abnormalities, a 4-month ketogenic diet intervention was associated with a 17% increase in self-reported life satisfaction and a 19% improvement in sleep quality, suggesting a potential link between dietary ketosis and subjective well-being in serious mental illness.

Why this might work

When the body burns fat for fuel instead of sugar, it produces ketones that increase calming brain signals and reduce overactive brain firing. This helps the brain rest better at night and feel more balanced during the day.
