Insulin Sensitivity

A relation of how well Insulin in the body is able to affect cells by inducing insulin-like effects. Insulin resistance is poor efficacy in affecting cells, and insulin sensitivity is good efficacy. Chronic Insulin resistance is one of the pathological signs of type II diabetes.

Insulin Sensitivity is a function of how well your body can handle glucose (blood sugar) through insulin secretion. Insulin is secreted from an organ called the pancreas in response to elevating blood sugar, and the less insulin that is needed to get the job done is how sensitive you are to insulin.

For a somewhat full review of insulin sensitivity, please refer to our FAQ page on increasing insulin sensitivity.



In general, being more insulin sensitive is better. If you had to blindly choose between being insulin sensitive or resistant, sensitive is probably the way to go.

Keep in mind that there are times where insulin resistance is good. The third trimester of pregnancy is one where insulin resistance is good as by hindering the ability of the mother to get glucose the baby gets more (up until a point, gestational diabetes is not that good) and fat loss diets and supplements tend to induce transient states of insulin resistance; the latter is not wholly bad because you should be having less food anyways and thus there really isn't any drastic spike in blood glucose to be resistant to on a fat loss diet (if you are doing it right).
