Sensibilité à l'insuline : le facteur que personne ne regarde

Everyone tells you to avoid insulin spikes. But what if it were exactly the opposite? Insulin is probably the most misunderstood hormone in the fitness world. It's often portrayed as the thing that makes you store fat, when in fact it's one of the reasons your body functions. In this video, I explain what insulin really is, what it does to your muscles and energy stores, and most importantly, what happens when your body starts to respond less effectively to it. You'll understand why it's a factor that matters as much for your physique as for your health. And at the end, I'll show you how to track your insulin levels. This is part 1 of a two-part series. In part 2, I'll give you all the concrete steps you need to improve it. ────────────────────────── 📩 Personalized Coaching / Follow-up Want to improve your body composition without going in blind? → Fill out the form here: https://docs.google.com/forms/d/1cs3b... → Or write "COACHING" in the comments / DM on Instagram @rz_physics I review each request personally. 📧 Contact: [email protected] 🔔 Subscribe for part 2! ────────────────────────── 📚 SCIENTIFIC SOURCES Structure of insulin Endotext (NCBI Bookshelf), reference NBK279029 — human insulin, 51 amino acids, A and B chains Adipose tissue, adipokines, and insulin resistance Rabe K. et al.
