This video features a conversation between Thomas DeLauer and Dr. Matt Bernstein, a Harvard anxiety doctor. They discuss how sugar and high insulin levels negatively impact brain health by increasing oxidative stress and overwhelming mitochondria, leading to reduced energy production and brain fog. Dr. Bernstein explains the concept of brain insulin resistance, its role in mental health conditions, and how it can lead to cerebral glucose hypometabolism. They also explore potential solutions such as ketogenic diets, MCT oil, exercise, and the role of neurotransmitters like GABA and glutamate. The discussion touches on the resistance to ketogenic diets in the medical community and how they can be used adjunctively with psychiatric medications.
