This 2017 research review examined whether ketogenic diets—high-fat, very low-carb eating patterns that put the body into ketosis—might be useful for treating psychiatric conditions. While ketogenic diets have been successfully used since the 1920s to treat drug-resistant epilepsy in children, scientists wanted to understand if this metabolic approach could also help mental health disorders.
The researchers found only 15 relevant studies, most of which were conducted in animals rather than humans. In animal studies, ketogenic diets showed promise for reducing anxiety-like and depression-like behaviors in rats and mice. For autism spectrum disorders, the diet improved behavioral symptoms in multiple animal studies. However, human studies were much more limited—consisting mainly of small case reports and two small open-label trials with mixed results.
The human evidence included some encouraging findings: a small study of 10 women with schizophrenia showed symptom improvement after 2 weeks on a ketogenic diet, and individual case reports described benefits for some patients with bipolar disorder and autism. However, other case studies showed no improvement, and the overall human evidence was too limited to draw firm conclusions.
This research highlights an emerging area where metabolic interventions might support brain health and mental wellness. While the evidence is still early-stage, it suggests that the metabolic changes from ketosis—including stable blood sugar and alternative brain fuel from ketones—might influence brain function in ways that could complement traditional psychiatric treatments. Patients interested in this approach should work closely with healthcare providers, as ketogenic diets require careful monitoring and may not be appropriate for everyone.
