Insulin resistance is clinically defined as the inability of the body to utilize insulin. Insulin is a hormone produced by the pancreas which regulates energy utilization. After eating, the pancreas is stimulated to release the hormone insulin. The insulin receptors which are found on every cell should normally respond to the hormone. With insulin resistance, there is unhealthy regulation of glucose, protein, and fat in the body. This condition commonly occurs in people with abdominal obesity, faulty lipid levels, and other factors associated with metabolic syndrome.
