In this lecture, Dr. Ben Bikman shifts the focus from how GLP-1 affects insulin to the overlooked reverse question: how insulin affects GLP-1. That shift reveals a deeper metabolic story about how chronic hyperinsulinemia may impair the body’s ability to produce GLP-1 over time.</p><br><p>Dr. Bikman first clarifies a key misconception. While GLP-1 can stimulate insulin under artificial conditions, in a real meal its dominant role is to slow gastric emptying, suppress glucagon, and reduce the need for insulin. In that sense, GLP-1 functions primarily as an insulin-sparing hormone. This makes the reverse question critical: what happens when the body produces less GLP-1?</p><br><p>Evidence shows that insulin-resistant, obese, prediabetic, and type 2 diabetic individuals consistently have a blunted GLP-1 response. Mechanistic studies indicate that chronic exposure to high insulin can make L-cells insulin resistant, reducing their ability to secrete GLP-1 when needed. This may create a vicious cycle: high insulin suppresses GLP-1, low GLP-1 removes metabolic brakes, and the resulting larger glucose and insulin spikes further worsen the problem over time.</p><br><p>The lecture reframes GLP-1 deficiency as a potential consequence of chronic hyperinsulinemia rather than an isolated defect. While GLP-1 drugs can bypass this dysfunction and improve outcomes, they do not repair the underlying cause—making long-term strategies that lower chronically elevated insulin levels more fundamental.</p><br><p>References:</p><p>For complete show notes and references, we invite you to become an Insider subscriber.
