Question

What is the % breakdown for each macronutrient of the diet for an endurance athlete?

a) 40% carbs, 30% fat, 30% protein
b) 60% carbs, 20% fat, 20% protein
c) 30% carbs, 40% fat, 30% protein
d) 70% carbs, 15% fat, 15% protein

Answer 1

The macronutrient breakdown for an endurance athlete is typically 60% carbohydrates, 20% fat, and 20% protein, which supports sustained energy levels and muscle repair during prolonged activity.

Step-by-step explanation:

The macronutrient breakdown for an endurance athlete typically follows a pattern that is different from that of the general populace. For endurance athletes, carbohydrates, which are the body's primary source of energy during prolonged activity, should make up a larger proportion of the diet. The recommended breakdown is often close to 60% carbohydrates, 20% fat, and 20% protein.

This macronutrient distribution allows for sustained energy levels during endurance sports. As the intensity and duration of exercise increase, the need for carbohydrates scales up accordingly, to about 3-10 g/kg/day. Protein intake is also crucial but does not need to be as high as carbohydrate intake, as it primarily serves to aid in muscle repair and growth. Healthy fats are necessary for overall health and to provide energy during prolonged periods of lower intensity exercise.
