Insulin sensitivity refers to how responsive the body's cells are to the hormone insulin. When an individual is insulin sensitive, their cells can efficiently take up glucose from the bloodstream with only a small amount of insulin. This is a hallmark of good metabolic health. In contrast, insulin resistance occurs when cells stop responding effectively to insulin, requiring the pancreas to produce higher amounts to maintain normal blood sugar levels.
Improving insulin sensitivity is a primary goal of many health and wellness protocols. Strategies such as reducing carbohydrate intake, practicing intermittent fasting, and consuming healthy fats help to lower chronic insulin levels and restore the cells' responsiveness to the hormone. High insulin sensitivity not only facilitates easier weight loss by allowing for better access to stored fat but also reduces the risk of developing type 2 diabetes and systemic inflammation.
