Insulin Resistance: The Metabolic Warning Sign You May Be Missing
Insulin resistance can develop long before type 2 diabetes—and many people don't know they have it. In this episode of the Mindfully Integrative Show, we break down what insulin resistance means, how insulin and blood sugar work together, common risk factors, and why metabolic health involves much more than the number on the scale.
You'll also learn:
- What insulin resistance actually means
- How insulin resistance relates to prediabetes
- Important metabolic numbers to know
- Why muscle, movement, nutrition, and sleep matter
- What the landmark Diabetes Prevention Program taught us
- Simple steps you can start using to support better metabolic health
Key takeaway: Metabolic health isn't about perfection. Small, sustainable changes in movement, nutrition, sleep, and body composition can meaningfully influence long-term health.

If you’ve ever felt tired, snacky, and stuck, while being told your blood sugar is “normal,” there’s a missing piece worth understanding: insulin resistance. I’m joined by Damairis Grossman, Doctor of Nursing and Family Nurse Practitioner, to unpack how insulin works, what hyperinsulinemia looks like in day-to-day life, and why this metabolic issue can build quietly before prediabetes ever shows up on paper.
We get specific about the signs people dismiss, like persistent fatigue, constant carb cravings, and unexplained weight gain. We also talk labs without the fear mongering: how A1C and fasting glucose can be useful, why ranges vary, and why a more conservative, prevention-focused mindset may help you spot problems earlier. Then we zoom out to the whole-body impact, including inflammation, cholesterol and triglycerides, waist circumference, and long-term risk for type 2 diabetes, cardiovascular disease, and stroke.
From there, we connect the dots between obesity and insulin resistance, including what research says about visceral fat and fatty liver driving metabolic disruption. We also discuss why “skinny fat” is real, why some people need more than willpower, and how weight loss can improve insulin sensitivity. GLP-1 medications come up as one tool, but we’re clear that sustainable lifestyle changes still form the foundation: whole foods, higher protein and fiber, fewer ultra-processed foods, daily movement, resistance training, and protected sleep.
If you want a practical place to start, we end with a simple challenge: ten minutes a day. Subscribe, share this with someone who’s been struggling, and leave a review so more people can find evidence-informed guidance. What’s your first 10-minute habit going to be?
