In plain English

Among adults with schizophrenia or bipolar disorder and metabolic issues, those who followed a ketogenic diet closely for four months showed larger improvements in both metabolic health and psychiatric symptoms than those who followed it less closely.

See the scientific wording

In adults with schizophrenia or bipolar disorder and metabolic abnormalities, a 4-month ketogenic diet intervention was associated with greater metabolic and psychiatric improvements among those who adhered to the diet, suggesting a dose-response relationship between dietary adherence and health outcomes.

Why this might work

When a person eats very few carbohydrates, the body switches to burning fat for fuel, which lowers blood sugar and insulin levels. This reduces inflammation throughout the body and helps brain cells use energy more efficiently, leading to better mental function and improved metabolic health.
