I searched him up briefly, he's an advocate for the ketogenic diet for neural health. It's not surprising because medical grade keto can solve various nerve related issues such as epilepsy and may even be beneficial for childhood ADHD and Autism. He also advocates abstaining from substances which may harm brain and nervous system health, such as marijuana and alcohol. He also advocates for a holistic program of stress management, sleep and nutrient optimization.
Yep, i looked him up too. He has books and YouTube channel/videos on "Brain Energy" theory and "Metabolic Theory of Mental Illness" which seem to make a lot of sense.
The fundamental problem is that the "Modern World/Economy" has forced us to orient our Circadian Rhythms, Diet, Lifestyle etc. around its needs rather than the other way around. This makes absolutely no sense. We are what we Eat and are affected by our immediate Environment (both Natural and Societal). Thus the Organism cannot be separated from its Environment and all problems both Mental and Physical must have its roots in maladaptation. So any solution would have to be holistic starting with diet and lifestyle changes. This has been the basis for ancient systems of medicine like Ayurveda, Yoga etc. and yet most of us have forgotten these holistic approaches but instead look only at symptomatic treatment i.e. "popping pills" when things go wrong.
