title: Metabolic efficiency of macronutrient utilization in humans.
abstract: 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.
