Carb addict” is a catchy phrase, but it collapses a complicated neurohormonal system into a moral failing wrapped in snack food language.

People like me, on GLP-1s aren’t discovering some secret weakness. We’re discovering that appetite, reward, satiety, and impulse are biologic systems — and when those systems are altered, the noise changes. That’s the point. Nobody says a patient with hypertension is a “salt addict” because a medication lowered their blood pressure. Yet somehow obesity still invites this strange Victorian need to turn physiology into character judgment. Also, if carbohydrates were uniquely addictive in the simplistic way internet nutrition tribes claim, then cultures built around rice, beans, lentils, fruit, and bread would have collapsed centuries ago into universal metabolic ruin. They did not. The problem is not “carbs.” The problem is hyperpalatable, engineered, calorie-dense food environments colliding with human biology that evolved for scarcity, not DoorDash at midnight. GLP-1s did not create discipline in people. They revealed what appetite feels like when the volume knob is no longer stuck on maximum.
