What’s the difference between physical activity and exercise when you live with type 1 diabetes? And why does it matter? 

Full show notes & transcript: Episode 18 page 

In this episode, I’m joined by Prof. Othmar Moser, exercise physiologist, guideline author, and fellow person with type 1, to break down: 

• Why 10 minutes of activity after meals is the easiest, most powerful place to start.
• The 20/20 and 40/40 rules — how 20 minutes of light movement can drop glucose by 20–40 mg/dL (1–2 mmol/L).
• How CGM feedback makes activity tangible and motivating.
• The Before–During–After playbook for structured exercise:
  • Before: meal timing, prandial reductions, AID temp targets, basal adjustments.
  • During: safe glucose range, 3–20 g carb top-ups, when to fingerstick.
  • After: the first hour of hypo risk, late-night dips, protein strategy, and therapy-specific caveats (AID vs Pump vs MDI).
