THE IMPORTANCE OF MACROS:
- Carbohydrates: The brain, kidneys, muscles and heart all need carbohydrates to function properly. Carbohydrates aid in the synthesis of certain amino acids. Fats can only be properly metabolized when carbs are present. All of our tissues have the ability to use the simple carbohydrate glucose as energy. When the body uses carbohydrates for energy, it can use other macronutrients (like protein) for muscle growth and strength.
- Protein: Enzymes, used for digestion and your immune system, are made of protein. Some essential hormones require protein to be produced. Proteins may be used as a source of energy when carbohydrates are not available. It is the major constituent of most cells, making up more than 50% of the dry weight of your body. It is used to produce new tissues for growth and tissue repair.
- Lipids (Fats): Lipids provide cushioning for organs and insulation for your body. They control maintenance of cellular membranes. Fats are also used as a high density energy source.
