Helping some small portion of the people who suffer from epilepsy is a far cry from "Best diet for mental health is keto diet".
Generally 15% total remission seizure free. Glut-1 defficiency is 80% total remission (20% of population with epilepsy). 50% of children will respond (helps but not totally).
For type 2 diabetes it's even better, like 70% IIRC med free.
I too can ignore the statement I am replying to, continuing arguments made elsewhere.
