Hosted by diabetes dietitian John Pemberton, this show blends science and real-life experience to make managing type 1 diabetes easier, clearer, and more human. Smart insights, practical tips, and honest conversations await.
It's all about C-Peptide and what it means for people living with T1D!
🕒 [00:09 ] Think all T1D is the same? Think again.
🕒 [02:14 ] Some people really do have it harder — and “brittle diabetes” might be real.
🕒 [04:37 ] Enter C-peptide: a marker of how much insulin your body still makes.
🕒 [06:10 ] Know your number:
• High: >200 pmol/L
• Intermediate: 30–200
• Low: <30
🕒 [09:11 ] Diagnosed young? You likely have lower C-peptide. John, diagnosed at 27, still has 220 after 10 years.
🕒 [10:20 ] High C-peptide = better time-in-range, fewer hypos, fewer complications.
🕒 [13:10 ] Why? More portal insulin + less glucagon = smoother control.
🕒 [14:01 ] Use your C-peptide to prioritise tech and tailor therapy (GLP-1s, HCL systems, nutrition).
🕒 [17:55 ] Most of all—be kind to yourself. It’s not weakness. It’s biology.
