The Claim
In a general adult population, individuals following a ketogenic diet report significantly higher levels of calmness, contentedness, and alertness, and lower levels of depression, anxiety, cognitive stress, emotional stress, and loneliness compared to individuals on non-specific diets, based on self-reported measures.
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.
Adults on a ketogenic diet report feeling calmer, more content, and more alert, and report less depression, anxiety, cognitive stress, emotional stress, and loneliness than adults on other diets, based on their own self-reports.

When the body burns fat for fuel instead of sugar, it produces ketones that calm overactive brain signals and reduce swelling in the brain, leading to less anxiety, more calmness, and clearer thinking.
