Insulin Resistance + Brain Health

June is Alzheimer’s & Brain Awareness Month, making it the perfect time to talk openly about the surprising connection between insulin resistance and brain health.

When we think of insulin, we usually think of blood sugar and diabetes. But did you know that insulin also plays a powerful role in your brain health? What Is Insulin Resistance?

Insulin is a hormone that helps shuttle glucose (sugar) into your cells so your body can use it for energy. When you become insulin resistant, your cells stop responding efficiently, and sugar starts to build up in your blood instead of fueling your cells.

This doesn’t just affect your metabolism—it impacts your brain, too.

Insulin’s Role in the Brain

Your brain is one of the most energy-hungry organs in your body, and it relies on glucose to function. Insulin helps your brain cells access that fuel. So when insulin resistance sets in, your brain begins to struggle with energy production – leading to symptoms like:

• Brain fog (difficulty concentrating, forgetfulness)
• Fatigue
• Mood swings or anxiety/depression
• Increased risk for Alzheimer’s disease

In fact, researchers often refer to Alzheimer’s as “Type 3 Diabetes” because of how closely it’s tied to insulin dysfunction in the brain.

What You Can Do to Protect Your Brain

The great new is, insulin resistance is reversible especially with early intervention. Here are a few evidence-based ways to protect your brain through better metabolic health:

• Balance your blood sugar: Focus on whole foods, protein-rich meals, fiber, and healthy fats. Avoid refined sugars and processed carbs.
• Move your body: Physical activity helps increase insulin sensitivity, which supports both your body and your brain.
• Prioritize sleep: Deep, restorative sleep is essential for blood sugar regulation and memory consolidation.
• Reduce inflammation: Chronic inflammation can worsen both insulin resistance and brain fog. Anti-inflammatory foods, stress management, and gut health all matter.

Next Steps:

Caring for your brain starts with caring for your metabolic health. If you’ve been experiencing persistent brain fog, low energy, or mood shifts, don’t brush it off—it may be your brain’s way of asking for support.

During this Alzheimer’s & Brain Awareness Month, let’s go beyond awareness and take action to protect one of our most vital organs—our brain.
