The Study

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

In simple terms

This study is like saying, 'My friend ate a new snack and felt better — so the snack must fix sadness.' But we don’t know if the snack did it, or if they just got lucky, or if something else changed. One person’s story isn’t proof.

What’s the bottom line?

A woman with PTSD who didn't improve with therapy or medicine tried a strict low-carb, high-fat diet — and her depression, anxiety, and PTSD symptoms vanished.
