Macros, short for macronutrients, are what make up the caloric content of food.
The three main macronutrients are carbohydrates, fat, and protein.
Both carbohydrates and protein provide 4 calories per gram.
Alcohol is also a macronutrient, but it provides no nutritional value and is therefore excluded from a macros- based approach.
CARBOHYDRATES
Carbohydrates are the body’s main source of fuel. When consumed, they are broken down into glucose and enter the bloodstream. When exercising, your body will first use the glucose in your blood stream.
FAT
Fat is used for energy after the body’s glycogen stores are depleted. Fat also helps the body absorb fat soluble vitamins, insulate and protect organs, produce new cells, and regulate many bodily functions.
PROTEIN
Protein is responsible for maintaining, growing, and repairing muscle tissues and ligaments. Protein is only used for fuel when the body does not receive enough energy from carbohydrates and fat.
FIBER
Fiber is found in carbohydrates. There are two kinds of fiber: soluble and insoluble. Soluble fiber is mainly found in starches. Insoluble fiber, mainly found in vegetables.
