Post-Lunch Insulin Sensitivity

Meaning

Post-Lunch Insulin Sensitivity refers to the degree of responsiveness of peripheral tissues, primarily muscle and adipose cells, to the glucose-lowering effects of insulin secreted following the midday meal. Optimal sensitivity ensures that blood glucose is rapidly and efficiently transported into cells for energy or storage, preventing prolonged postprandial hyperglycemia and the subsequent reactive hypoglycemia that causes the “afternoon crash.” Maintaining high sensitivity in this period is a critical factor for sustained energy, metabolic health, and reducing the risk of developing insulin resistance.
