Insulin resistance is not just a metabolic problem. It is a brain problem.
New research is confirming what functional medicine practitioners have known for years: when your cells stop responding to insulin properly, your brain pays the price. Memory. Focus. Mood. Processing speed. All of it takes a hit.
Researchers are now calling Alzheimer’s disease “Type 3 Diabetes” because the same insulin dysfunction driving metabolic disease is found in the brains of patients with cognitive decline.
This is not a coincidence.
When insulin signaling breaks down in the brain, neurons cannot get the fuel they need. Inflammation increases. Plaques accumulate. And the symptoms people write off as “just getting older” start showing up earlier and earlier.
Brain fog. Memory lapses. Mood swings. Trouble concentrating.
These are not inevitable. They are signals.
