I explain how high GI foods drive a rapid pancreas insulin response that can take 2 to 3 hours to settle, and how exercise creates a VIP backdoor for glucose. I also cover reactive hypoglycemia when insulin overshoots after big hits like syrupy pancakes, causing crashes below 70 mg per deciliter. I ask you to notice your afternoon energy valleys and what you ate before them, then to flatten the curve with fiber, protein, or a 10 to 15 minute walk after eating.
