Macros is the abbreviation for macronutrients, which refers to carbohydrates, fats, and proteins.
Carbohydrates (which provide energy), fats (which have a very bad reputation, when, in reality, they contribute to cell growth, protect organs, self-regulate our temperature and also provide energy) and proteins (which build and repair muscles).
They are called macros because we need to consume them in larger quantities than micronutrients (vitamins and minerals).
The proportion of macros will vary depending on your goals, physical activity level, and the amount of exercise you do on a daily basis. If you train hard every day, you'll need to increase your protein intake to regain muscle mass and prevent future injuries. However, if you're more into cardio, you'll need to increase your carbohydrate intake to prevent glycogen depletion.
For those following the keto diet, it is a very important tool, as they must be very careful with the amount of carbohydrates and fats they consume, especially.
We recommend the MACROS app to track your nutritional intake and plan your daily diet.
