EP:16. What a Continuous Blood Glucose Monitor can Tell you About your Health

Have you ever wondered what happens to your blood glucose after you eat, or why the same meal can affect two people very differently? In this episode, I explore what a continuous glucose monitor, or CGM, can reveal about your health. We look at glucose spikes and dips, why some seemingly healthy foods may cause a bigger response than expected, and how sleep, stress and movement can influence your readings. I also explain how combining carbohydrates with protein, healthy fats and fibre may help create a steadier glucose response, and why a simple walk after eating can make a meaningful difference. Using a CGM isn’t about fearing food or trying to achieve a perfectly flat glucose line. It’s about becoming curious, understanding your individual responses and using that information to make practical, sustainable choices for your long-term health. This episode has been adapted from a live session inside The Whole Health Revolution, where members can join me each week, explore a new health or nutrition topic and have their questions answered live. ### Chapters - (00:00:00) - Introduction: Why Blood Sugar Matters - (00:00:48) - Scale of the Diabetes Problem - (00:01:52) - Understanding Insulin Resistance - (00:03:50) - Signs and Symptoms of Insulin Resistance - (00:04:42) - Blood Sugar, Inflammation and Chronic Disease Links - (00:06:01) - Introducing Continuous Glucose Monitors (CGMs) - (00:07:07) - How a CGM Applicator Works (Demonstration) - (00:08:31) - Individual Responses to Food (Oats Example) - (00:09:43) - Using Movement After Meals to Lower Glucose - (00:10:43) - Client Case: Walking After Meals - (00:11:37) - How to Structure a CGM Trial - (00:12:41) - Tracking Meals and Exercise in the App - (00:14:14) - Personal CGM Experiments: Matcha and Sushi Surprises - (00:16:17) - Perimenopause, Insulin Resistance and Prevention - (00:18:07) - Access, Cost and Availability of CGMs - (00:19:17) - Reversing Type 2 Diabetes and Working with Medication - (00:21:27) - Closing Thoughts and Encouragement to Try a CGM
