Macros, short for macronutrients, are the three main categories of nutrients that your body needs in large amounts to function and provide energy. These macronutrients are protein, carbohydrates, and fats. Each plays a distinct role in your body's health and energy supply:
- Protein helps build and repair tissues, including muscles, bones, hair, and enzymes. It provides 4 calories per gram.
- Carbohydrates are the body's primary energy source, supplying glucose for muscle movement, brain function, and other processes. They also provide 4 calories per gram.
- Fats support nutrient absorption, hormone production, temperature regulation, and protect organs. Fats provide 9 calories per gram, making them the most calorie-dense macro
People often count macros to track their intake of these nutrients, which helps them make informed dietary choices beyond just counting calories. This approach can assist in achieving goals like weight loss, muscle gain, or overall health improvement by understanding not only how many calories are consumed but also where those calories come from and how they affect the body
. In summary, macros are the essential nutrients-protein, carbs, and fats-that fuel your body and are tracked to optimize nutrition and energy balance.
