Macros is short for macronutrients, which are the nutrients your body needs in large amounts. The three main macronutrients are carbohydrates, proteins, and fats, which provide the body with energy and support many bodily functions. A macro-balanced diet involves consuming these macronutrients in specific ratios to meet individual needs. This approach can help maintain a healthy weight, support muscle gain, improve athletic performance, and reduce the risk of chronic diseases. The recommended ratio of macronutrients may vary depending on factors such as age, health conditions, and overall goals. Counting and tracking macros can be a useful tool for weight loss and achieving fitness goals, but it may also be time-consuming and socially restrictive. It is important to ensure a balanced and varied diet that meets all nutritional needs, including micronutrients such as vitamins and minerals. Consulting a registered dietitian or nutrition professional can help individuals determine the appropriate macro ratios and ensure their nutritional needs are met.

Macronutrients: proteins, carbohydrates, and fats
Macronutrients are the nutrients in food that your body needs in large amounts. The three macronutrients are carbohydrates, proteins, and fats.
Carbohydrates
Carbohydrates are the primary source of energy for the body. They can be found in grains, fruits, vegetables, and legumes. Carbohydrates provide the body with fuel and energy. The amount of carbohydrates a person needs varies. Some people thrive on lower-carb diets, while others require a diet higher in carbs. The recommended intake of carbohydrates is 45% to 65% of your daily calories.
Proteins
Proteins are essential for many processes in the body. They are made from long chains of amino acids and are necessary for cell building and repair. Enzymes, neurotransmitters, hormones, and antibodies are all made from proteins. The Recommended Dietary Allowance is 0.8 grams of protein per kilogram of body weight per day. For a person who weighs 150 pounds, that is about 54 grams of protein per day. Individual needs will vary based on age, activity level, medical history, and health goals.
Fats
Fats are another important source of energy for the body and are necessary for the absorption of certain vitamins and minerals. Fats also serve as an energy reserve, provide insulation, and protect organs. Unsaturated fats, such as those found in olive oil, avocado, fatty fish, and meat, are associated with decreased cardiovascular risk and improved health outcomes. Saturated fats, on the other hand, should comprise no more than 10% of your daily calories. The recommended intake of fats is 20% to 35% of your daily calories.
A macro-balanced diet focuses on balancing these three macronutrients in specific ratios to meet individual needs. This approach can help maintain a healthy weight, support muscle gain, improve athletic performance, and reduce the risk of chronic diseases. It is important to note that everyone's macronutrient needs are different, so it is recommended to consult a dietitian for advice on appropriate macro ratios.

Counting macros vs calories
Counting calories and macros are both tools used to manage food and energy intake, often with the aim of helping with weight loss, gain, or maintenance. Both methods require tracking food intake, usually with an app, to count the number of calories or macros one is consuming. However, they differ in that calorie counting gives a set number of calories to eat each day, taking into account one's height, weight, age, activity level, and weight goals, whereas macro counting focuses on the macronutrient profiles of the food consumed—namely, protein, fat, and carbohydrates.
Counting macros involves counting calories, but not vice versa. This is because macros contain calories. Each macronutrient provides a different amount of energy per gram: carbohydrates and proteins provide four calories per gram, while fats provide nine calories per gram. Thus, by counting macros, one is inherently also counting calories.
Counting macros can be more effective in helping one achieve their weight and health goals because it places more emphasis on what one is eating, rather than the specific focus calorie counting places on how much energy one is consuming. Macro tracking also takes into account one's nutrient intake to some extent, while calorie counting does not. By manipulating different macronutrient intakes, one can more directly impact their health and weight outcomes. For example, high-protein diets have been shown to help grow lean muscle mass, as well as leaving one more satiated throughout the day and therefore less likely to overeat.
However, counting macros may be time-consuming, socially restrictive, and confusing. It can also be misleading if one falls into the trap of IIFYM (If It Fits Your Macros). Furthermore, focusing too much on the numbers can lead to nutrient deficiencies and poor health outcomes if one is not eating enough nutrient-dense foods.

Health benefits of a macro-balanced diet
A macro-balanced diet focuses on balancing macronutrients—proteins, carbohydrates, and fats—in specific ratios to meet individual needs. This approach offers several health benefits, including:
Weight Management
Balancing your macronutrients can help with weight management. By consuming the right ratio of macronutrients, you can regulate your appetite and control your food intake, leading to a reduction in overall calorie consumption and weight loss. For example, if most of your calories are coming from simple carbohydrates, you are more likely to gain weight. On the other hand, a drastic reduction in carbohydrates can put your body in a metabolic state called ketosis, where it becomes very efficient at burning fats.
Energy Levels and Athletic Performance
A macro-balanced diet can improve your energy levels and enhance athletic performance. Carbohydrates are the primary source of energy for the body, and they can be found in grains, fruits, vegetables, and legumes. Fats are also an important source of energy, providing more calories per gram than carbohydrates or proteins.
Muscle Gain and Maintenance
Macronutrient balance supports muscle gain and enhances muscle maintenance. Proteins are essential for the formation, management, and recovery of muscles. Additionally, building lean muscle mass is promoted by paying attention to your macronutrient ratio, helping to reduce fat storage.
Chronic Disease Prevention
Adopting a macro-balanced diet can help reduce the risk of chronic diseases. This is achieved by ensuring your body gets the right balance of essential nutrients, supporting overall health and well-being.
Nutrient Absorption
A balanced intake of macronutrients aids in the absorption of certain vitamins and minerals. For example, fats are necessary for the absorption of fat-soluble vitamins like vitamins A, D, E, and K.

Calculating your daily calorie needs
A macro-balanced diet focuses on balancing macronutrients – proteins, carbohydrates, and fats – in specific ratios to meet individual needs. This approach helps to maintain a healthy weight, supports muscle gain, improves athletic performance, and reduces the risk of chronic diseases.
> Calories/day = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (years) + 5
And for assigned female at birth:
> Calories/day = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (y) - 161
Once you know your daily calorie needs, you can determine the appropriate macronutrient ratio to meet your health and fitness goals. It is recommended to get 45–65% of your daily calories from healthy carbohydrates, 10% to 35% from protein, and 20% to 30% from fats.
For example, if you are consuming 2,000 calories per day and want to get 50% of your daily intake from carbohydrates, you can calculate the grams of carbohydrates to consume using the following formula:
> (Total daily calories x macronutrient percentage) / calories per gram
In this case, carbohydrates and proteins provide 4 calories per gram, while fats provide 9 calories per gram. So, for a 2,000-calorie diet with 50% carbohydrates, you would consume 500 grams of carbohydrates, providing 2,000 calories.
By calculating your daily calorie needs and determining the appropriate macronutrient ratios, you can design a meal plan that supports your health and fitness goals while ensuring you consume a balanced and nutritious diet.

Micronutrients: vitamins and minerals
A macro-balanced diet focuses on balancing macronutrients—proteins, carbohydrates, and fats—to meet an individual's needs. Micronutrients, on the other hand, are vitamins and minerals that are required in smaller amounts. They are essential for carrying out a range of normal bodily functions and can be divided into macrominerals, trace minerals, and water- and fat-soluble vitamins.
Vitamins are necessary for energy production, immune function, and blood clotting, among other functions. Water-soluble vitamins, such as vitamin C and the B-complex vitamins (e.g., vitamin B6, vitamin B12, and folate), must be regularly provided by the diet as they are not stored in the body. Fat-soluble vitamins (vitamin A, vitamin D, vitamin E, and vitamin K) tend to accumulate in the body. Deficiencies in vitamin B12 are common among vegans, vegetarians, and elderly individuals.
Minerals play a crucial role in growth, bone health, and fluid balance. Common mineral deficiencies include iron, which is prevalent among preschool children, menstruating women, and vegans.
To achieve a balanced diet, it is recommended to consume a variety of foods, including fruits, vegetables, whole grains, good protein sources, and healthy fats. While supplements can be beneficial in certain cases, they should not be used as a substitute for a healthy, balanced diet.
It is important to note that the requirements for vitamins and minerals vary based on factors such as age, sex, and physiological state. Consulting a healthcare professional or using an online calculator can help determine your specific needs.
