Insulin 101 (Part 2): What Causes Insulin Resistance and How to Fix It


Listen Later

In Part 2 of this series on insulin, Kayla breaks down six common causes of insulin resistance and the practical lifestyle changes that can help improve it. 

While diet certainly plays a role, factors like muscle mass, sleep, stress, hormones, and visceral fat can have a major impact on blood sugar and insulin levels.

You’ll also learn how insulin resistance develops years before blood sugar or A1C levels change, and how tools like continuous glucose monitors (CGMs) can help uncover what’s really going on beneath the surface.

In this episode, Kayla covers:

  • 6 major drivers of insulin resistance
  • How constant snacking and ultra-processed foods can worsen blood sugar 
  • The critical role muscle mass plays in insulin sensitivity
  • Why visceral fat creates a vicious metabolic cycle
  • Common signs and symptoms of insulin resistance
  • 3 lifestyle strategies to improve insulin sensitivity
  • When intermittent fasting may help—and when it may backfire

If you’re wondering whether insulin resistance may be impacting your health, Kayla shares how to spot the early warning signs and start improving metabolic health today.
