Age, Metabolic Health, and Glucose: Kara Collier

Kara joins us to discuss metabolic health, glucose as we age, how stress impacts our glucose spikes, the importance of protein, and more. 

“Typically what you see in the ICUs actually are complications from lifestyle-related chronic conditions. Something like needing an urgent leg amputation because of uncontrolled diabetes or needing to be put on dialysis because of uncontrolled cardiovascular disease. These were the types of instances I was seeing over and over and that experience led to some frustrations wishing I could help people sooner so they never had to end up there in the first place.” 

“Just like a car has an engine that interacts with many different components of the car to run it, we have a similar cellular engine and that would be considered metabolic health as a whole.” 

“It’s not that we never have our glucose move, it’s just that we want to keep it in these  healthy ranges and we don’t want to overload those places where glucose can go.” 

“If somebody is relatively healthy, their metabolic health looks good overall but their fasted glucose level is always high, typically the #1 thing that’s happening is chronic stress.” 

“With nutrition specifically, the framework we try to teach people is: master the basics, understand the fundamentals that everyone should be doing and then be malleable and empirical. Be willing to be flexible in your approach based off of your own personalized data because we all are unique.” 

“About the worst thing that you could do for your glucose levels is a liquid form of sugar.”
