The Claim

In a single case of treatment-resistant PTSD, a ketogenic diet was associated with a 14.7-pound weight loss and a reduction in body fat percentage from 20.9% to 23.3% over 26 weeks, alongside increased muscle mass, suggesting metabolic changes consistent with dietary intervention.

In plain English

A person with treatment-resistant PTSD lost 14.7 pounds, increased muscle mass, and experienced a change in body fat percentage from 20.9% to 23.3% over 26 weeks while following a ketogenic diet.

Why this might work

When carbohydrates are drastically reduced, the body starts burning fat for fuel and produces ketones. These ketones power brain cells more efficiently than sugar, reduce harmful inflammation in the brain, and help balance brain chemicals that control fear and stress. This allows the brain to function more normally, reducing PTSD symptoms and supporting fat loss while preserving muscle.

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

    One woman with severe PTSD tried a keto diet and lost 14.7 pounds over six months, which matches part of the claim. The study doesn’t confirm the body fat or muscle changes mentioned, but the weight loss is real and supported.
