EP033 Why Your Blood Sugar Spikes After Meals (Even If You're Healthy)

Are you eating right, exercising, and maintaining a healthy weight, but still seeing massive blood sugar spikes after meals? You are not alone! In this episode of The Diabetes Podcast, Richie and Amber tackle one of the most Googled questions about diabetes: "How high should blood sugar go after eating?" We break down normal physiology, the hidden drivers behind post-meal spikes (like stress, sleep, and muscle mass), and why your waist-to-hip ratio matters more than your BMI. Plus, discover actionable, real-world strategies you can use today to flatten your glucose curve and take back control of your metabolic health.

KEY TAKEAWAYS

• Muscle is your metabolic engine: Muscle mass disposes of up to 80% of post-meal glucose. Building muscle through resistance training is key to flattening spikes.
• Waist-to-hip ratio beats BMI: Visceral fat (fat stored around your organs) drives insulin resistance. Measuring your waist-to-hip ratio is a much better indicator of metabolic risk than stepping on the scale.
• Food sequencing matters: Eating non-starchy vegetables and protein before your carbohydrates can reduce blood sugar spikes by up to 30%.
• Movement is medicine: Just 10 minutes of walking after a meal can drop your blood glucose by 20 to 40 points almost immediately.
