Low Carb High Fat - Ketogenic

The second-ever pilot trial (published in the Journal of Affective Disorders) is making waves: a virtual medically supervised ketogenic diet showed impressive improvements in people with moderate to severe depression, including nearly 7 out of 8 study completers achieving clinical remission.

In this interview, Dr. Bret Scher sits down with lead researcher Dr. Elisa Brietzke, Professor of Psychiatry at Queen’s University, to explore the inspiration, execution, and implications of this study.

What began as a bold idea, that metabolic dysfunction plays a role in depression, evolved into a fully remote clinical intervention. Despite skepticism and challenges, the results were clear: ketogenic therapy can be safely and effectively implemented in a remote outpatient setting. Participants who completed the study experienced improvements in depression, anxiety, and anhedonia (the loss of pleasure).
