Insulin sensitivity means your cells respond efficiently to insulin, so a small amount effectively moves glucose into cells. Insulin resistance means more and more insulin is required to do the same job. You want sensitivity. In a small isocaloric trial of eight overweight men with prediabetes, eating earlier in the day improved insulin sensitivity without weight loss, which separates timing from calories; it is the right kind of evidence at a size that cannot prove anything on its own. Resistance is a step toward type 2 diabetes; that it also drives fat storage and hunger is the carbohydrate-insulin model’s proposal, and the model’s own proponents call the human evidence inconclusive.
This companion covers what insulin does, the ideal of sensitivity, the problems of resistance, how resistance develops (chronic insulin exposure, excess fat, inactivity), and how to improve sensitivity through fasting, exercise, and dietary changes. (5 min read)
