Insulin is almost universally considered a hormone whose primary purpose is to regulate blood glucose levels. Indeed, it does this. But is that the whole picture? When we look at what governs pancreatic insulin secretion inside the beta-cell, it’s about total energy and the versatility of the short-term energy supply, not about glucose. When we look at what insulin does to energy metabolism, it does far more than regulate blood glucose: it governs how we use energy and what we do with it.
