Hello Tooters, has anyone #Neurodifferent or with #MentalHeath issues come across the #BrainEnergy / #Metabolism theory?

I’m not 100% sold by any means however I’m certainly intrigued. Here’s an episode of (the very good) #TheArtOfManliness podcast that dives into it. Very interested to hear other opinions.
