Summary of Importance of Macronutrients:
Carbohydrates are your body's main source of energy for completing work; simple sugars are good for immediate bursts of energy, and complex carbs can be stored for a burst of energy later on. Proteins build the structures in your body, from your hair to your muscles. Fats are used to make chemicals in your body, and as a sustained, long lasting source of energy. Your diet should be about 40-50% Carbs, 25-35% protein, and 20-30% fat.
