The hormone that gets sugar into cells and promotes storage.
Insulin is an anabolic pancreatic hormone secreted in response to rising blood glucose. It allows glucose entry into cells and stimulates storage as glycogen and fat.
Insulin is secreted by beta cells of the pancreas. It activates GLUT4 transporters in muscle and adipose tissue, stimulates glycogenesis and protein anabolism. Insulin resistance (precursor to type 2 diabetes) is promoted by sedentary lifestyle, abdominal obesity and ultra-processed diet.
Regulate blood glucose, stimulate energy storage, promote muscle anabolism.
Physical exercise improves insulin sensitivity — it is the best preventive treatment for insulin resistance.
Insulin is not a hormone to fear — it is chronic resistance to it that is problematic.
