Key takeaways:
This week, we're diving into the science of cellular health and aging - from rapamycin's potential to revolutionize how we think about longevity, to David's success story using continuous glucose monitoring, to the surprising ways insulin affects our brain function. Join us as we explore both groundbreaking research and practical strategies for better brain health.
Featured Biomarker
Insulin: The Blood Sugar Manager
What it is: A hormone that facilitates glucose uptake from the bloodstream into cells. Insulin is pivotal for maintaining stable blood sugar levels. Elevated insulin levels may indicate insulin resistance, where cells fail to respond adequately to insulin's signals.
Why it matters: Insulin resistance has been shown to increase cognitive decline and Alzheimer's risk. Over time, this condition may lead to type 2 diabetes, obesity, and cardiovascular diseases. Elevated insulin can disrupt brain insulin signaling, leading to neuronal loss and impaired memory function.
How to improve it: You can optimize insulin function through consistent daily movement and limiting processed carbohydrates. Time your meals thoughtfully and manage stress levels, as both impact insulin sensitivity. Focus on quality sleep and consider using a continuous glucose monitor to understand your body's unique responses to different foods and activities.

Small Changes, Big Impact: David's CGM Story
"I never thought about checking my glucose until my BetterBrain testing revealed increasing insulin resistance," shares David, 63.
Following his BetterBrain consultation recommendation, he started using a continuous glucose monitor to understand how different foods and activities affected his body.
David found that two simple changes made a dramatic difference:
- Switching to eggs for breakfast instead of his usual fruit and yogurt
- Taking 10-minute walks after meals
"The CGM data was eye-opening. I could see how these small changes dropped my post-meal glucose spikes significantly. I have more consistent energy throughout the day and I'm excited to recheck my fasting glucose in my follow up testing."
BetterBrain Takeaway:Everyone's body responds differently to foods and activities - that's why personalized tools like continuous glucose monitors are so powerful. They help you understand your unique patterns and make targeted changes that actually work for your body.

Rapamycin: A Soil Discovery's Promise for Brain Health
Bottom line: Rapamycin, a drug discovered in Easter Island soil, shows potential to extend lifespan, though it's currently only FDA-approved for other uses.
Rapamycin targets a cellular receptor called mTOR, which regulates cell growth and survival. When partially inhibited, cells become more efficient at cleaning up harmful proteins. This "cellular housekeeping" effect makes rapamycin particularly interesting for brain health.
Animal studies have shown remarkable results, including 20-30% increases in lifespan and improvements in cognitive function. While human data is still limited since the drug is only approved as an immunosuppressant, many physicians already prescribe it "off-label" for longevity benefits.
Currently, using rapamycin for brain health remains experimental. There's no standardized protocol, and insurance won't cover it. But for those working with knowledgeable physicians, it represents an intriguing option for cognitive protection.
You can read more about rapamycin in our GreyMatters blog post, or listen to the Peter Attia Drive episode to learn more about the molecule, its history, how it works, and the most recent evidence on its effects.
