Macronutrient Ratios

Meaning

Macronutrient ratios refer to the proportional distribution of the three major energy-yielding nutrients—carbohydrates, proteins, and fats—within an individual’s total dietary intake. These ratios are a critical determinant of metabolic health, influencing insulin sensitivity, body composition, and hormonal signaling pathways. Clinical nutritional protocols often manipulate these proportions to achieve specific therapeutic goals, such as weight management or improved glycemic control.
