1:30 I asked Dr. Masley how he came to write a book about the brain? Dr. Masley just published The Better Brain Solution. https://www.barnesandnoble.com/w/the-better-brain-solution-steven-masley-md/1126646685#/ Dr. Masley explained that in his clinic he looks at 100 markers of aging. He looks at arterial plaque growth, cholesterol, lipids, sugar, etc. He also looks at brain function, brain processing speed, memory, attention span, reactivity, and executive brain function. He also looks at food intake, nutrient intake, fitness, stress management, and toxic exposure. He has an easy to follow five step plan that improves brain processing speed by 25-30%.
2:45 I answered that that is great because cognitive problems, neurodegenerative conditions like Alzheimer’s Disease, are really on the rise and are now the leading cause of death in women, exceeding even cardiac and breast cancer. Dr. Masley said that he agreed and the number one most expensive disease is memory loss at $215 million per year and that is supposed to double in the next 12-15 years. It’s because the number one cause of memory loss is elevated blood sugar. I mentioned that some practitioners are now calling Alzheimer’s Disease Type III Diabetes due to this relationship between blood sugar and insulin resistance.
3:58 I asked Dr. Masley to explain what does blood sugar have to do with the brain? Dr. Masley said that it has to do with insulin resistance. Insulin is the hormone that helps us to store energy. When we eat carbs, whether it’s a healthy carb like broccoli or blueberries or whether it’s a refined carb, which causes a much bigger blood sugar surge like sugar or flour, the insulin rises in order to push the sugar into the cell. That’s a normal function, just like muscle cells. We push glucose in, and we build glycogen. When we go for our next workout, that glycogen in that muscle cell is ready to burn as energy. The challenge is if we don’t have a healthy lifestyle …if we don’t work out enough; if we eat too many refined carbs … our cells become full. They no longer respond to insulin. In fact, they become insulin-resistant. Once they’re full of energy, they say, “No, we’re not listening any more. We can’t store any more energy.”
Dr. Masley continued to explain that when brain cells become full of glucose, they shut down and stop working. Insulin resistance makes brain cells unable to process and use energy, so if we do a PET scan on the brain of someone who’s super fit and healthy, it would likely light up like a Christmas tree. When we do a PET scan and we look at energy burn on brain cells in patients with insulin resistance, it’s pretty quiet. The brain is unable to process glucose’s energy. It’s dysfunctional. They have brain fog. They’re forgetful. They walk into a room; they don’t know why they’re there. They read a passage in a book, and they have to keep rereading paragraphs and they can’t remember people’s names. Their brain’s not functioning, and if that’s not just a day or so, but it’s ongoing, that insulin resistance state, the brain cells being unable to use energy, they become dysfunctional. Then they die, and if they die, then every time a brain cell dies, the brain shrinks a little bit. If you have millions of brain cells dying, your brain is shrinking a lot, so insulin resistance, this abnormal blood sugar regulation, literally makes us unable to use our brain, shuts our brain down,
