Chronically high insulin causes visible skin changes—skin tags, velvety neck skin, hair loss on toes—years before people recognize metabolic disease. Dr. Annette Bosworth reveals how late-night eating and processed foods quietly trigger insulin resistance, leading to cancer, depression, and accelerated aging, then walks through a 12-step protocol to lower insulin and restore metabolic health. Skin tags in armpits and groin, darker velvety skin on the neck, and disappearing toe hair are early physical markers of chronic high insulin, not cosmetic issues but signs of metabolic disease.
