Managing Glucose During Exercise Is Hard
You feel like you’re doing everything right. You lower your insulin before training. You take extra carbs. You check your CGM religiously. But your glucose still crashes mid-session or spikes unpredictably afterward.
I see this pattern when athletes with Type 1 Diabetes are referred to me by their diabetes care team. They’ve followed the standard protocols. But their glucose stays unstable during activity. The problem is that standard advice assumes your body responds like the average person with T1D. When it comes to exercise and glucose, what works on average rarely works for you.
Generic protocols don’t fit you
Standard advice works on average populations. But with T1D, “average” means almost nothing for your specific response. Your insulin sensitivity changes with exercise type, duration, and intensity. Optimal strategies vary widely depending on your insulin treatment. You need a personalized framework, not a one-size-fits-all guideline.
Hybrid closed-loop systems can fail during exercise
HCL systems are powerful tools. But they can cause hypos if not managed carefully around activity. Most systems don’t reduce insulin fast enough before exercise. Or they keep correcting high glucose until your blood sugar drops hard mid-session. Without a tailored plan for your specific HCL system and activity, automation can make things worse.
You need expert guidance
Without a framework built for you, you’re guessing. You need practical strategies based on evidence and clinical experience. Someone who can analyze your CGM data in context of your exercise patterns. Someone who can build a plan that fits your specific insulin sensitivity, your training schedule, and your glucose response.
That’s why I built Diabetes Performance
To give you the depth, tools, and guidance you need to thrive with T1D.
For over a decade, I’ve worked with active people and athletes with Type 1 Diabetes at Leiden University Medical Centre.
I kept seeing the same gap: no reliable, evidence-based resource for exercise glucose management at the depth people need. So I built one.
Diabetes Performance gives you in-depth articles, practical tools, and personalized consultations based on your data and goals.
