Yes!! There was a 2022 study in France where keto brought schizophrenics out of psychosis. I imagine in the next few years, we will find out a large part of mental illness (depression and anxiety inc) is brain inflammation. If the pharma companies let the research happen, that is.

Laughing at their article photo choice because a plant-based keto diet is ridiculous, NGMI.

This does not mean you can't eat plants and be keto. But it works a lot better if your fat and protein come (together) from animal meat.
