The keto cure for “Type 3” diabetes
Breakthrough science has led to a new understanding of why brain function falters: Much like diabetes, mental decline is caused by problems with blood sugar (glucose) and insulin. When blood-sugar levels are chronically elevated, the brain becomes resistant to insulin, so neurons don’t get the fuel they need—and “Type 3 diabetes” sets in. “This can lead to fog, learning difficulties and even Alzheimer’s,” says Mark Hyman, M.D., author of The Blood Sugar Solution. But researchers at the University of Texas Southwestern Medical Center in Dallas have found that eating a highfat, low-carb keto-style diet for just six weeks reduces insulin resistance by 18% and enhances memory performance by 35% in older adults.
