Ketogenic and Nutritional Interventions for First Episode Bipolar Disorder
Purpose
This is a randomized, controlled clinical trial to assess the effects of the ketogenic diet in combination with treatment as usual on brain energy metabolism and psychiatric symptoms in individuals with first episode bipolar disorder and schizoaffective disorder.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Active Comparator Ketogenic diet arm |
Eligible participants assigned to the ketogenic diet arm will be asked to follow the ketogenic diet (KD) for 12 weeks in addition to any ongoing medications (e.g., mood stabilizers and/or second-generation antipsychotics). Participants will receive weekly and as needed diet counseling from a registered dietician. Participants will be asked to monitor and report their blood ketone levels each day via a finger-prick device provided by the study team. Participants have the ability to opt into an optional open label phase where they can continue on the ketogenic diet with the daily finger pricks for another 12 weeks after the 12-week main study. |

|
Active Comparator Dietary Guidelines for Americans arm |
Eligible participants assigned to the Dietary Guidelines for Americans (DGA) arm will adhere to the Dietary Guidelines for Americans in addition to any ongoing medications (e.g., mood stabilizers and/or second-generation antipsychotics). Participants will receive weekly and as needed diet counseling from a registered dietician. Participants will be asked to monitor and report their blood ketone levels each day via a finger-prick device provided by the study team. Participants have the ability to opt into an optional open label phase where they can switch to the ketogenic diet with the daily finger pricks for 12 weeks after the 12-week main study. |

Detailed Description
Several lines of evidence show energy metabolism and redox dysregulation in bipolar disorder and psychotic disorders. Ketogenic interventions targeting energy metabolism are promising therapeutic approaches to improve mood and psychosis in bipolar disorder and other psychotic disorders. Early intervention is also critical to helping people achieve their goals for recovery after a first episode. Investigators aim to use multimodal imaging and metabolic measures to study the effects of a ketogenic diet intervention on energy metabolism and psychiatric symptoms in individuals with first episode bipolar disorder and schizoaffective disorder. This 12-week randomized controlled trial will assess the benefits of a ketogenic diet in combination with treatment as usual compared to a standard diet. Investigators will measure the effects of nutritional ketosis on brain redox and energy metabolism and other neurometabolic markers using magnetic resonance spectroscopy. Furthermore, investigators will measure the effects of the ketogenic diet on mood and psychotic symptoms and metabolic measures such as insulin resistance.
