Insulin Sensitivity Rhythms

Meaning

Insulin Sensitivity Rhythms describe the predictable, daily fluctuations in the responsiveness of target cells, particularly muscle and adipose tissue, to the action of insulin. Typically, the body exhibits higher insulin sensitivity in the morning and a progressive, natural decline into the evening, reflecting a fundamental circadian regulation of glucose metabolism. Recognizing and respecting these rhythms is paramount for metabolic health, as mistimed food intake, especially high-carbohydrate meals in the evening, can exacerbate insulin resistance and contribute to chronic metabolic disease.
