Palmer was clear that nobody should stop psychiatric medications without careful supervision. While one of the patients in his study worked with her doctor to safely taper off her psychiatric medications, the other decided to stop all of them suddenly on her own.

“Let me be clear, that was an unmitigated catastrophe for her. She became severely psychotic. She was hospitalized for over two months,” Palmer said. That patient continued her diet throughout her hospitalization, and had to go back on medication before tapering off safely.

if you read through the lines it’s two supervised cases and only fully supervised case to be clear. Despite the keto diet the second patient was, in fact, psychotic, until the medication was reintroduced.
