Macronutrient utilization in humans is a complex phenomenon, with each macronutrient having its separate storage and utilization pathways. Carbohydrate and fat are to some extent interdependent, but while carbohydrate utilization is greatly dependent on intake, fat is not. The food quotient of the diet is important in determining how nutrients are utilized and stored, and thus is an important determinant of body composition. Also, the effect of these two macronutrients on food intake differs. The bioenergetics of utilization of the macronutrients are discussed.
人体对常量营养素的利用是一个复杂的现象，每种常量营养素都有其独立的储存和利用途径。碳水化合物和脂肪在一定程度上相互依存，但碳水化合物的利用很大程度上取决于摄入量，而脂肪则不然。饮食的食物商数在决定营养素如何被利用和储存方面很重要，因此是身体组成的一个重要决定因素。此外，这两种常量营养素对食物摄入量的影响也不同。本文讨论了常量营养素利用的生物能量学。
