24 Jul Calories and macros!
Calories are made up of macro-nutrients. But what are they??
Nutrients are substances needed for growth, energy and other body functions.
Macro-nutrients are those nutrients required in large amounts that provide the energy needed to maintain body functions and carry out the activities of daily life. There are 3 macronutrients – carbohydrates, proteins and fats.
Carbohydrates are the preferred source of energy for your body. Carbohydrates provide your body with the simple sugar glucose, which is carried to each of your tissues and cells and converted to energy.
Protein provides the structure to all of the cells in your body. Proteins also help build enzymes and hormones, maintain the acid-base balance in your body, transport various substances throughout your cells and help keep your immune system healthy. In the absence of carbohydrates, proteins can provide your body with energy.
Protein plays a huge role in your diet. Protein will help preserve lean muscle tissue if you are in a caloric deficit, and help build muscle if you are trying to bulk up. It also helps control your appetite better and will keep you satisfied for longer periods of time.
Although fat is often associated with negative health implications, fat is essential for a healthy diet. Fat helps cushion your organs, provides insulation to help you maintain body temperature and allows you to absorb fat-soluble vitamins. Your body has an unlimited ability to store fat, so fat can also provide with you energy when you haven’t eaten for an extended period of time.
