"...a peptide hormone produced by beta cells of the pancreatic islets, and it is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of, especially, glucose from the blood into fat, liver and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both."
"Insulin also signals the fat cells to take up fat and hold on to it."
"All foods raise insulin to some degree. Refined carbohydrates tend to raise insulin the most and fatty foods the least, but insulin still goes up in both cases. Therefore, the most effective method of reducing insulin is to avoid all foods altogether ... Regularly lowering insulin levels leads to improved insulin sensitivity — your body becomes more responsive to insulin."
