The conditions that doctors treat as separate problems—obesity, Type 2 diabetes, Alzheimer’s, heart disease, and even polycystic ovary syndrome—may share a single underlying driver: insulin resistance.
Insulin resistance develops quietly, long before symptoms appear, and it is far more responsive to lifestyle than most people realize.
What Insulin Does
After we eat carbohydrates or sugar, glucose enters the bloodstream, triggering the release of insulin—a hormone that helps move sugar out of the blood and into the muscles and liver, where it can be used for energy or stored for later.
