    I did, but the study was not talking about insulin resistance as a positive, the way you are. It was talking about natural selection for a gene that increased Insulin production. And how during times of starvation in the past having higher natural insulin levels was a net positive factor in carrying a baby to term.

    Insulin is a vital hormone, and very necessary. Insulin Resistance is nothing but bad times.

    "But when the gene’s low-activity version arose somewhere in Eurasia an estimated 8,100 years ago, that same glucose-boosting quality may have helped women maintain their pregnancies during lean times."

    "GIP helps stimulate insulin production after a meal. Insulin, in turn, helps cells more efficiently use sugars from food. Too little insulin can lead to high levels of sugar in the blood, a symptom of diabetes. But higher blood sugar levels may also help fetuses grow. The new form of the gene may have given people an evolutionary advantage to survive famines, the researchers speculate."

    Insulin promotes the movement of glucose out of the blood and into the tissue. During lean times it was more important to make certain that it got to the baby, rather than into the mothers tissues, so the mother became insulin resistant.

    That's how I'm reading it.

    The GIP gene adaptation that is talked about would cause there to be a lower level of insulin produced. How can producing less Insulin lead to Insulin resistance? I mean, the effect is the same (higher blood glucose levels). But they are not the same thing.
