Insulin Resistance Explained
- Insulin resistance isn't a simple on/off switch, but varies across tissues like the pancreas, liver, and muscles.
- It develops due to excess energy, particularly fatty acids, disrupting insulin signaling in these tissues.
Testing for Insulin Resistance
- Get a fasting insulin test and calculate your Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) online.
- Consider an HbA1c test, but remember that it is an indirect measure.
The Carb Myth
- Insulin resistance isn't primarily caused by carbs, but by excess energy, especially saturated fats.
- Replacing refined carbs with saturated fats can worsen insulin resistance.
