Protein to Carbohydrate Ratio

Meaning

The Protein to Carbohydrate Ratio is a fundamental nutritional metric that expresses the relative proportion of protein intake compared to carbohydrate intake in a person’s diet, typically calculated by weight or energy percentage. This ratio is a key determinant of the postprandial metabolic and endocrine response, significantly influencing the secretion of insulin and glucagon, and subsequent blood glucose homeostasis. Strategically optimizing this ratio is a fundamental strategy in hormonal health for managing insulin resistance, promoting sustained satiety, and supporting the maintenance of lean muscle mass, which is particularly relevant in the context of aging and metabolic syndrome.
