The Claim

In a 45-year-old woman with treatment-resistant PTSD due to military sexual trauma, a 25-week ketogenic metabolic therapy intervention was associated with a reduction in PTSD symptom severity from a PCL-5 score of 32 to 2, along with complete resolution of depressive and anxiety symptoms as measured by PHQ-9 (10 to 0) and GAD-7 (6 to 0).

In plain English

A 45-year-old woman with severe PTSD from military sexual trauma experienced a reduction in PTSD symptoms from a PCL-5 score of 32 to 2 and complete resolution of depression and anxiety symptoms after following a ketogenic diet for 25 weeks.

See the scientific wording

In a 45-year-old woman with treatment-resistant PTSD due to military sexual trauma, a 25-week ketogenic metabolic therapy intervention was associated with a reduction in PTSD symptom severity from a PCL-5 score of 32 to 2, along with complete resolution of depressive and anxiety symptoms as measured by PHQ-9 (10 to 0) and GAD-7 (6 to 0), suggesting a possible link between nutritional ketosis and symptom improvement in this individual.

Why this might work

When the body runs on fat instead of sugar, it produces ketones that brain cells use as clean fuel. This fixes energy shortages in fear and emotion centers, reduces harmful inflammation, and balances brain chemicals that control anxiety and stress. As a result, the brain stops overreacting to threats and returns to normal function.

  1. Study: Ketogenic metabolic therapy for treatment-resistant post-traumatic stress disorder (PTSD): a retrospective case report

    One woman with severe PTSD who didn’t get better with therapy or medicine tried a strict low-carb, high-fat diet for 25 weeks — and her PTSD, depression, and anxiety symptoms disappeared, according to her doctor’s tests. The study says this diet might have helped.
