Metabolic health emerges as a new frontier in psychiatry
How your metabolism could alter your mental health
The episode examines whether improving insulin signaling and energy metabolism could complement psychiatric care, while stressing that the evidence remains early and incomplete.
- 1Impaired glucose use and insulin signaling may connect metabolic health with schizophrenia, bipolar disorder, and depression.
- 2Medically supervised ketogenic therapy may alter brain fuel use and improve some metabolic and psychiatric markers.
- 3Potential benefits remain uncertain because long-term risks and rigorous clinical evidence have not been fully established.

Sethi traces her investigation of metabolic psychiatry to a patient whose schizophrenia symptoms improved alongside weight loss.
The brief
Shebani Sethi’s experience with a patient whose schizophrenia symptoms improved alongside weight loss led her to investigate metabolism as a psychiatric factor.
Metabolic psychiatry examines how impaired glucose use and insulin signaling may influence schizophrenia, bipolar disorder, and depression beyond brain chemistry alone.
Sethi explains that medically supervised ketogenic therapy shifts the brain from glucose to ketone bodies, with possible anti-inflammatory and neurological effects.
The central tension is evidence versus enthusiasm: early improvements are promising, but long-term risks and limited research demand cautious interpretation.
The episode frames metabolism as a possible mental-health lever while emphasizing that ketogenic treatment should be medically supervised and evidence-based.
