A Rocket Scientist Homeschooler's Inside...

About this episode

bengreenfieldfitness.com/levels

As I've mentioned many times before on podcasts, I've been using something called a "Continuous Glucose Monitor" (CGM) at various intervals throughout my life for about 4 years or so.

 

 

Considering that, as I write about here, I consider glycemic variability (which is exactly what these CGM's track) and inflammation (which is a bit more difficult to measure as it typically requires a visit to a lab) to be my top two key biomarkers for health and longevity, my use of a CGM has given me some very valuable data on how my body responds to certain foods, supplements, exercises, lifestyle practices, and even emotions.

But how does a CGM work, exactly? 

What does the really tiny "filamentous" needle actually measure?

How do you get yours to "stick" for long periods of time, or in water? 

How does the phone gather data from the sensor, and is EMF a concern?

Does the sensor have to be calibrated to a blood glucose reading due to the fact it is recording interstitial fluid vs. blood? 

Is this type of thing, from an insurance standpoint, that is only available to diabetics? 

What do you do about activities that cause high glucose excursions, such as exercise/sauna/coffee etc., which wind up decreasing the metabolic score when, long-term, those are all glucose stabilizing/insulin sensitizing activities?

Are there certain supplements or herbs that do the best job controlling blood glucose?

 

 

I explore these questions and many others in this podcast with Josh Clemente. Josh is a rocket scientist and worked at SpaceX for 6 years, managing the team that designed the life support systems in their space shuttles. Overtime, he started to notice extreme levels of fatigue and experienced volatile spikes and crashes of energy throughout his day. For someone that worked out consistently and followed the guidelines for what he believed to be healthy practices, it didn’t seem to add up. After experimenting with glucose monitoring, he realized that he was pre-diabetic, borderlining on fully-blown diabetic, and that the foods he was eating were having a significant impact on his performance. It was this discovery and struggle to derive actionable insights from his glucose monitoring that led him to start Levels.

 

Today at Levels Health, Josh and his team are revolutionizing the way people think about their metabolic health. And why is metabolic health so important? Before Levels, an average person had no way of understanding how efficiently or inefficiently their body was producing energy. Levels enables you, using a new CGM system, to access and understand this information in real-time, so you can start making better diet and lifestyle choices to avoid those energy peaks and valleys.
