The Claim
In a single case of treatment-resistant PTSD, initiation of a ketogenic diet was associated with the achievement of nutritional ketosis (beta-hydroxybutyrate ≥1.5 mmol/L) and concurrent resolution of depressive, anxious, and stress symptoms as measured by DASS-42 and PHQ-9 over 25 weeks.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In one person with treatment-resistant PTSD, starting a ketogenic diet coincided with measurable ketosis and a reduction in symptoms of depression, anxiety, and stress over 25 weeks.

When the body runs on ketones instead of sugar, brain cells get more energy and produce less harmful waste. This fixes damaged communication between brain areas that control fear and emotion, stops harmful inflammation in the brain, and balances the chemicals that calm and excite nerve cells. As a result, the brain stops overreacting to stress and returns to normal function.
What the research says
1 studyOne woman with severe PTSD that didn’t get better with any other treatment started eating a ketogenic diet, and her depression, anxiety, and stress symptoms disappeared over six months—along with measurable ketones in her blood.
