What if your body could warn you before a relapse happens? In this fascinating episode, Dr. Vera Tarman sits down with Bob Messerschmidt — biomedical engineer, inventor, and one of the architects behind the original Apple Watch's health-sensing technology — to explore a surprisingly simple but powerful biomarker: the erythrocyte sedimentation rate (ESR).
Bob is the founder of Core Health and has developed an FDA-registered at-home device that tracks chronic low-grade inflammation over time. For those of us in the food addiction and recovery world, this conversation opens a compelling new door: could inflammation tracking be the missing feedback loop for people working to stay abstinent from ultra-processed foods?
🎙️ IN THIS EPISODE:
- Bob's personal health journey and how weight struggles led him to inflammation science
- What ESR (erythrocyte sedimentation rate) is — and why it fell out of favor before we understood chronic inflammation
- Why inflammation is now understood to underpin nearly all chronic disease
- How ESR differs from CRP (C-reactive protein) and why its "slowness" is a feature
- What does a high ESR score mean — and what you can do about it
- Anti-inflammatory lifestyle interventions that move the needle (including one surprising nighttime trick)
- How the Core Health device works: a simple weekly finger-stick test from home
- The feedback loop concept: how seeing your own data creates self-efficacy and behavior change
- Whether inflammation can precede a relapse — and what the data currently shows
- How ESR compares to a continuous glucose monitor (CGM) as a recovery tool
- Bob's thoughts on the Theranos dream — and whether democratized blood diagnostics is truly possible
- The future of non-invasive glucose monitoring and wearable health tech
🍒 BOB'S ANTI-INFLAMMATORY TIPS FROM THE EPISODE:
- Tart cherry juice (4 oz before bed — also improves sleep!)
- Ketogenic eating patterns
- Vegan dietary approaches
- Quality sleep
- Cold plunges
- Grounding practices
