In this episode, we talk ALL things fasting, glycemic variability, personalized CGM experiences, and of course, metabolic flexibility!
“The better question is - how metabolically flexible are you? That’s going to be the contingent factor that will determine what will or won’t affect your fast.” Mike Mutzel
Top Takeaways:
Being consistent with fasting is probably a better approach than being super aggressive. The more data we know about our day to day decisions - diet, mindset, stress response - the more empowered we are. Learn how to integrate different practices into your life related to stress management, sleep, fasting, breathing, etc. so you can work towards becoming more flexible and resilient.  Show Notes:
