Summary Introduction
Introduction: Macronutrients like carbohydrates, fats, and proteins are the major three sources of energy. The carbohydrates provide energy for muscles and brain by breaking down into glucose. The carbohydrates constitute about 45-65% of energy (or calories); fats constitute 20-35% of energy; and protein constitutes about 10-20% of energy.
