We trace how insulin resistance in the brain—often called type 3 diabetes—starves neurons amid plenty, driving oxidative stress, inflammation, amyloid build‑up, and vascular damage that dull memory and focus. We share a practical plan: combination eating, short post‑meal walks, and stress control to restore steady fuel and clearer thinking.
• the brain’s glucose dependence and the insulin paradox
• insulin resistance inside the brain and “type 3 diabetes”
• oxidative stress, chronic inflammation, and amyloid pathways
• glycation damage to brain microvessels and reduced flow
• why stability beats spikes for memory and focus
• combination eating with fiber, protein, and healthy fats
• soluble fiber’s gel effect and slower glucose release
• a 10‑minute walk that lowers post‑meal glucose
• cortisol’s surge and how stress overrides good meals
• a simple weekly experiment to feel sharper
Pick one meal this week, maybe one that tends to be higher in carbs for you lunch, perhaps, or dinner, and just commit to fully balancing that one meal. Make sure it has good protein, plenty of fiber, and some healthy fat alongside the carbs. And then this is key, right after you finish eating. Go for a gentle, easy 10 minute walk, no power walking needed. Just move. Maybe leave your phone behind. Did you notice? Pay attention, not just physically, but mentally. See if you feel a difference in your focus, your energy levels in that hour or two afterwards compared to usual.
