Insulin even be slightly over-corrected) by the end of the test. Even during digestion, in general, one or two hours following a meal, insulin release from the pancreas is not continuous, but oscillates with a period of 3–6 minutes, changing from generating a blood insulin concentration more than about 800 p mol/l to less than 100 pmol/l. This is thought to avoid downregulation of insulin receptors in target cells, and to assist the liver in extracting insulin from the blood. This oscillation is important to consider when administering insulin-stimulating medication, since it is the oscillating blood concentration of insulin release, which
Insulin resistance associated with excess body weight. A possible explanation is that both insulin resistance and obesity often have the same cause, systematic overeating, which has the potential to lead to insulin resistance and obesity due to repeated administration of excess levels of glucose, which stimulate insulin secretion; excess levels of fructose, which raise triglyceride levels in the bloodstream; and fats, which may be absorbed easily by the adipose cells, and tend to end up as fatty tissue in a hypercaloric diet. Some scholars go as far as to claim that neither insulin resistance, nor obesity really are metabolic disorders "per se",
