Macros, short for macronutrients, are the nutrients that the body needs in large amounts, including carbohydrates, fats, and proteins. Counting macros has become a popular diet trend in recent years, as it helps people understand where their calories are coming from and achieve long-term weight loss. Each macronutrient plays a role in keeping the body full and satisfied, which helps prevent overeating, reduces cravings, and enables weight loss. Carbohydrates provide energy, protein helps rebuild and repair the bodys tissues, and fat is important for satiety, hormone balance, and helping the body absorb certain vitamins. Counting macros involves tracking the grams of proteins, carbs, or fat that a person consumes. People count their macros to reach weight loss goals, build muscle mass, and balance blood sugar levels. However, it can be time-consuming, socially restrictive, and confusing. It is important to note that a macro diet could lead to a lack of nutrient diversity, and precise calculations are required to track macros, which can contribute to disordered eating behaviors. Therefore, it is recommended to consult with a registered dietitian before starting a macro diet.
