Fitness junkies and personal trainers have more than likely heard the phrases “Did you hit your macros?” and “That doesn’t fit my macros” frequently. 

But if you aren’t a fitness professional or haven’t yet dipped a toe into macro counting, you may have some lingering questions regarding the very trendy diet plan and what “if it fits your macros (IIFYM)” is all about.

This begs the question: What exactly are macros, why do you need to count them, and how do you begin?

This article will explain all you need to know about macros and their importance. Also, we’ll show you how counting macros is helpful for everyone, regardless of fitness goals.

This post will discuss:

  • What are macros?
  • What is macro counting?
  • Determining macros for fat loss and building lean body mass
  • Pros and cons of macro counting
  • How to count macros
  • How to track macros and food intake


What Are Macros?

The first step with counting macros is answering the question: What is a macro? The term “macros” refers to macronutrients. Your body requires large quantities of these nutrients in order for it to function optimally. There are 3 different macros: protein, fat, and carbohydrates.

Not only does each macronutrient pack its own unique health benefits, but each also provides you with calories.

What Are Micronutrients?

Compared to macronutrients, micronutrients are various compounds essential for optimal health that are required in smaller amounts. These are vitamins and minerals.

We must consume over 13 essential vitamins and numerous other minerals in our diet. When it comes to vitamins, there are two groups:

  • Fat-soluble vitamins: Vitamins that are absorbed by fat for transfer.
  • Water-soluble vitamins: Vitamins that dissolve in water.

What Is A Macro Diet?

Let’s get into the question on everyone’s mind: What is counting macros? A macro diet is a flexible dieting method that allows a person to choose the foods they want, as long as they fit into a predetermined macro ratio.

Macro counting differs from plans such as the Metabolic Confusion Diet, as it requires counting calories and then also tracking macronutrients to fit within that daily calorie goal.

An example of this is a person on a 2,000-calorie diet who wants to hit a macro split of 30/30/40 (Protein/Fat/Carbs). This means they must choose foods to eat that will hit their intended macro target. In practice, this means that 30% of their daily calories come from protein, 30% from fat, and 40% from carbs.

It sounds more complicated than it is. And don’t worry, we’ll show you how to make tracking calories easier a little later on in the article. For now, let’s talk about each macronutrient in more detail.

Macro 1: Protein

In a way, how much protein you need per day is the most important macro to focus on and is generally the first macro determined in a diet.

Compared to fat and carbs, there is far less variation in the amount of protein a person eats across all fields. This number remains pretty steady, no matter your other macros. Protein is made of strings of amino acids, which act as the building blocks of tissue. It’s the primary macro used to build and repair muscle.

There are 4 calories per gram of protein.

Optimal Protein Intake:

The RDA for protein is 0.8 grams per kilogram of body weight (0.8g/kg).

However, this number is minimal for the entire population, including the sick and elderly. In addition, it’s the basic amount needed to support healthy liver function.

A 30-year-old guy going to the gym, following a workout split, will need more protein compared to an inactive man who never works out to support the amount of stress he’s putting on his muscles. Therefore, the recommended protein intake for athletes is 1.6-2.2g/kg¹.

Many people do better using a high protein intake as they generally see better muscle gains as well as improved body composition.

This occurs due to one of the proven health benefits protein provides. It aids in weight loss². This occurs through many mechanisms, including:

  1. Increases satiety (makes you feel fuller): Protein is harder to break down and stays in your stomach longer. This causes you to feel full longer after a high-protein meal.
  2. Mitigates muscle loss during a calorie deficit: When you lose weight and are under stress, your body may break down muscle for energy. Having larger amounts of protein mitigates this.
  3. Has a higher thermic food effect (TFE): This means your body requires a larger amount of calories to digest and utilize it. It’s like free calories!

Best Protein Sources:

Protein is found in both animal products and plant foods. Generally speaking, animal protein will be a better protein source in terms of quality and quantity.

Some of our favorite sources of high protein low-fat foods are:

  • Chicken breast
  • Lean red meat
  • Fish (Eat 2 servings of fatty fish a week)
  • Eggs
  • Low-fat milk

Macro 2: Dietary Fat

Fat is largely misunderstood by the public. It’s generally associated with excess body fat, but that is due to overconsumption. In reality, our bodies require a significant amount of fat to support life.

The suggested minimum dietary fat intake is at least 25% of a person’s diet. You can go higher if you would like, but aside from Keto, most diets are in the 25-45% range.

A few functions provided through dietary fat include warmth, fatty acids, protection of our organs, hormone production, and stored energy. It’s also required to transport fat-soluble vitamins.

Fats have a significant amount of calories at 9 calories per gram.

Best Fat Sources:

There are numerous types of fat. To keep things simple, stay away from or limit anything with trans fats or saturated fats. These are mainly found in things like fast food and processed food.

Aim for healthy fats. Some good sources include avocado, fatty fish (2 servings a week), nuts, and eggs, which can increase testosterone³.

Macro 3: Carbs

Again, carbs are vastly misunderstood. Carbs are your body’s main fuel source for intense activities, like HIIT, making them vital for sufficient energy.

Carbs are basically sugar in different molecular structures. That’s a wildly simplified explanation, but for the purpose of this discussion, it will do. When digested, carbs are broken down into a single molecule of sugar (glucose), which is then stored in our muscles to be used as fuel.

Best Carbs Sources:

Most people would do awesome if they cut out anything with added sugar. If you only get your carbs from natural sources, it’s not going to make a massive difference whether it’s from fruit or pasta. 

That said, some of our favorite carb sources are:

  • Oatmeal
  • Sweet potato
  • Brown rice
  • Quinoa
  • Fruit

Optimal Carb Intake:

Carbs are vital for optimal performance, particularly as you take on a tough gym session, like these assault bike workouts, and we love them. However, when compared to fats and protein, our bodies can function with very low amounts.

We only need to get around 5% of our calories from carbs as our brains require glucose. Our other muscles and organs can get energy from other fat and protein if needed.

But the diets of some endurance athletes may include a carb intake of 70%-80%⁴! That said, your average lifter will likely be around 3-5g per kilogram of body weight.

One important thing to keep in mind is carb’s role in manipulating calories, which is almost exclusively done by increasing and decreasing your carbs. Your protein and fat intake should remain consistent.

Counting Calories vs Counting Macros: What’s The Difference?

The first question some people may ask themselves is: What’s the difference between whether I count calories or count macros? At the end of the day, both methods wind up using the same calorie intake.

However, there is a significant difference that sets these methods apart.

What Is Calorie Counting?

Tracking calories puts all of the emphasis on, you guessed it, calories, in order to get into a deficit, maintain weight, or build muscle.

But simply counting calories can be too simplistic and neglect other parts of a person’s nutrition. A person’s diet consists of a lot more than just calories.

In fact, this entire article is about your macros. In addition, there are also micronutrients that can have a large effect on the body’s health and performance.

Further, it ignores the source of the food. This can lead some people to determine if a product is “healthy” or not purely by looking at the calories.

For example, here are a couple of examples of how only using calories results in poor choices.

  • Avocados are bad as they’re high in calories.
  • Coke is better than milk as it has fewer calories.

Neither assumption would be correct.

What Is Macro Counting?

In comparison, counting macros shifts the interest to tracking how many macros you need to eat. While your calorie goal stays the same, you focus on hitting your desired macro ratio.

This is important because it causes people to look at the foods they eat, so they’re not bypassing any of the three macros.

Further, this leaves less room for junk food as a person must eat nutrient-dense foods to hit their prescribed macros within their calorie goal. This aligns with the 80-20 rule diet, which emphasizes high-quality, nutritious foods the majority of the time.

Benefits Of Counting Macros

Now, let’s go through some of the reasons a macro diet might be good for you.

1. It’s guaranteed To Work.

The first benefit of tracking macros for weight loss or any other goal is that it’s going to work. It’s one of the few things we can guarantee in nutrition and fitness.

The end goal of any weight loss program, or clean bulking diet, is to control calories. Counting them and keeping track is the only way to ensure you don’t overeat.

Plus, if you hit your macros and stay within your calorie goal, you’ll lose weight. It’s science.

2. You’ll Learn About Your Body.

If it doesn’t work, or you find you are gaining/losing too much weight, you can adjust your macro ratio or calorie intake.

Even though we’re confident your body will respond, nothing is 100% guaranteed. Some people seem to operate better with different macro splits as they handle compounds differently than others.

The only way to discover this is by tracking macros and calories while paying attention to body changes. Start by figuring out your daily macros, and then even determining things like how much protein you need per serving to hit those, and adjust as needed.

3. It Allows Some Freedom With Food Choices.

This is what differentiates it from other diets. At the end of the day, just about every diet that has been introduced is a “macro diet.” The difference is that it either prescribes what macro ratio to use (keto, “low-fat”) or it dictates what foods you eat (Mediterranean, paleo, vegan).

We’re not saying that any of the above are bad diets, nor are we saying they’re great. What we’re saying is that with macro counting, as long as you’re hitting your macro goals (which you set), you get to select the foods you eat to reach your target. Essentially, there’s more freedom.

Drawbacks Of Macro Counting

If macro counting is almost guaranteed to work, why isn’t everybody doing it? These are a few reasons why.

1. It’s hard to track and takes time.

This primary drawback explains why more people don’t track their macros. It’s hard, especially at the beginning.

And truth be told, they’re right. While we can make it easier with the use of a macro counterit still takes time. There’s a learning process involved, even with a macros calculator helping you out. Unfortunately, this part can be a bit obnoxious. Anyone who tells you it’s not is lying.

However, it does get easier the longer you do it (what doesn’t?).

Further, not taking control of your health will eventually lead to many annoying things, like heart disease and constant insulin injections. The point being is that while it can be hard to learn, the payoff is huge. Plus, you’ll start to prioritize healthy habits, like eating the right foods before a workout and after a workout, to support your macro and muscle-building goals.

2. It Can Lead To Eating Disorders.

Eating disorders can occur anytime weight loss is involved, meaning this isn’t specific to a macro diet. However, counting calories and tracking macros have the potential to create an unhealthy obsession with tracking food.

You likely even know someone who shows disordered eating patterns, doing things such as checking the nutrition label of everything they eat and stressing out because they tracked their calories incorrectly.

This obsession develops from the fear of eating too many calories or missing your macro target. While you want to hit your macros pretty consistently, you will never get them exactly, nor will eating a few too many cancel the health benefits.

However, we know that knowing these things doesn’t necessarily fix the issue. If you are prone to eating disorders or obsessive behaviors, please keep this in mind and be mindful of any signs. In fact, if you have a history of eating disorders or obsessive behaviors, you should first speak to your doctor.

3. A Macro Diet Doesn’t Distinguish Between Healthy & Unhealthy Foods.

Similar to the issue with calorie counting, a macro diet still leaves room for unhealthy food choices. Don’t get us wrong. Following one will probably result in better overall food selection. But not everyone sees it this way or uses the diet with the correct mindset.

For example, your macro diet quality can be greatly increased by choosing healthy foods that deliver the same macros. This includes things like choosing healthy fats vs. saturated fats and complex carbs instead of added sugar.

To some people, fat is fat, and carb is a carb. This isn’t true. That is like saying fuel is fuel. However, there’s a definite difference between diesel, premium, and regular.


You May End Up Hitting Your Macros But Missing Your Micros

Some will choose to eat any type of food as long as it fits their macros. For example, choosing Mcdonald’s 10-piece chicken nuggets as a protein source delivers 20+ grams at 440 calories.

The problem is that there are other important nutrients your body needs and some compounds your body doesn’t need, such as saturated fat, which nuggets are full of.

Further, you must consume all of your vitamins and minerals consistently. Not only do some of these processed foods have larger amounts of calories, but they also have smaller quantities of vitamins and minerals. In other words, even if you do hit your macros, you could still miss your micros.

That said, if you concentrate on using nutrient-dense foods to hit your macros, strategically including things such as the best protein powders, lean protein sources, fruits, veggies, and whole grains, hitting your micros shouldn’t be an issue.

How To Determine How Many Macros To Eat

Figuring out how to count macros first includes finding out how many macros you need to eat. You’ll start by finding out how many calories you need, and then you’ll take your calorie tracking a step further.

This process contains a few steps, but we’ll try to keep it simple.

Step 1: What’s The Best Macro Ratio?

Depends on who you ask. Seriously.

If you ask us, we like to keep things moderate except for protein. We suggest a higher protein intake for the majority of people as it works great regardless of your goal.

  • Fat: Above, we said your diet should be at least 25% fat. However, we like to bump that to 30% as athletes probably do better with a slightly higher amount.
  • Protein: If you do the calculations, 1.6-2.2g/kg of body weight equals about 25-35% of a person’s diet. Start with 30% and adjust as needed. If you start incorporating protein into everyday meals, like protein French toast and protein coffee, you’ll find you can easily hit this.
  • Carbs: Carbs will fill in the rest of your diet, which is 40%.

When reading a macro split, it’s labeled as protein/fat/carbs. So this would be a 30/30/40 split.

Step 2: Estimate Your Total Daily Energy Expenditure.

Now that you know your macro nutrients ratio, you need to calculate how many calories you burn during the day. This is called your total daily energy expenditure, or TDEE for short. Your TDEE consists of four different values:

  • Basal metabolic rate (BMR) (60%): Your BMR is the number of calories burned for life function. This includes things like brain activity and respiration.
  • Exercise (20-30%): Includes any activity with the intent to exercise, like your 4-day split, for example, or playing sports.
  • Non-exercise activity thermogenesis (NEAT) (5-10%): Includes activity without the intent of being exercised, such as walking to your car.
  • Thermic effect of food (TFR) (10%): TFR is the energy our body needs to digest and utilize food.

To find this number, you must first calculate your BMR. There are multiple equations that can be used for this. For example, the Mifflin St. Jeor equation is popular. It looks like this:

  • Men: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5 (kcal / day) 
  • Women: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) -161 (kcal / day)

You then calculate this number by your activity level.

  • Sedentary = 1.2
  • Lightly active = 1.375
  • Moderately active = 1.550
  • Very active = 1.725
  • Extra active = 1.9

That said, you can also find a good TDEE calculator on the web that will not only provide you with your maintenance calories but may also have a macro calculator that provides you with your daily macros split.

Regardless of which TDEE calculator or equation you use, it’s important to note that you will need to track your progress and likely need to tweak these numbers as everyone’s needs are highly individual. Think of the daily calories provided by a calculator as a good starting point.

Step 3: Divide Your Daily Calorie Intake By Your Macro Split.

Once you know your total daily energy expenditure, take the macronutrient ratios you’ve decided to go with (like 30/30/40) and calculate your macros.

Remember that the ratio is only from the calories. So once you determine how many calories should come from each macro, you then divide that by the number of calories in 1 gram of each macro.

Take an imaginary person who weighs 100kg (~220 pounds). He has a 3,000-calorie diet and wants to use a 30/30/40 split.

1) 30% Protein:

  • 30% x 3000 calories = 900 calories
  • 900 calories divided by 4 cal/g = 225 grams of protein (notice this is close to 2.2g/kg)

2) 30% Fat:

  • 30% x 3000 calories = 900 calories
  • 900 calories divided by 9cal/g = 100 grams of fat

3) 40% Carbs:

  • 40% X 3000 calories = 1,200 calories
  • 1,200 calories divided by 4cal/g = 300 grams of carbs

So the macro diet for this person would be 225 grams of protein, 100 grams of fat, and 300 grams of carbs.

If after walking through this, you’re still feeling like it’s too much math required when it comes to how to count your macros, you can download an app like MyFitnessPal, which serves as a macro calculator for weight loss. Simply pay the monthly membership, and they will do the majority of the macro-calculating work for you.

How Do You Count Macros? (And Ways to Make It Easy!)

Now we get to the “complicated” part: Tracking macros, which is an essential part of the macros diet. When figuring out how to count macros, it will take a bit of time to get used to.

The only way to be sure of what you’re eating is if you make your own food. You can use packaged foods once in a while, but what your read on the nutrition label isn’t always correct.

This means when it comes to how to count macros, you need to learn how to cook at least some basic meals (using nutritious whole foods). This muscle-building meal plan will provide you with some inspiration.

Strategies for Tracking Macros:

There are a ton of different websites that show you the nutritional information of various foods. However, we strongly recommend just downloading a macro counting app, like MyFitnessPal, which we touched on above.

Not only does a counting macros app help provide the calorie content of different foods, but it also serves as a great macro counter, requiring minimal effort (aside from inputting your food) from you.

For example, if you’re cooking chicken breast you can search the app for chicken breast, select how many grams or ounces of that food you’ll be eating, and the app will record that information for you.

This is why we also strongly recommend you buy a digital food scale to weigh your food. Remember to weigh your food before cooking it (raw meat and vegetables).

How To Make Tracking Macros Easier:

When you cook your food, make a larger quantity so you can then divide it into multiple meals. Basically, meal prep!

Learn some easy meals that are easy to calculate. The easiest meal should have a minimal amount of ingredients. We like these bulking breakfasts if your goal is building muscle. When you count calories, don’t get too caught up on precision either.

Here are some guidelines for building a meal.

  1. Start with a protein. Only count the protein, only worrying about its fat and carbs if it’s significant.
  2. Choose one source of carbs. Most natural carbs don’t have fat (sweet potato or brown rice) so won’t need to worry about counting fats with your carbs.
  3. Use oil or butter for fats (if needed). This is an easy method to add your fats and some flavor.
  4. Add vegetables for the remaining calories.
  5. Be sure the total calories are correct and the macros are within range.

Examples of meals that easily make this possible include a sandwich, crockpot meals, and smoothies. Crockpot meals let you easily toss in all of your macros, and a dinner of steak, sweet potato, and spinach checks all your macro boxes. A pasta meal consisting of chicken, noodles, and tomato sauce is another meal that will help you stay on macro-counting track.

Once you have cooked a few meals, write down the recipes along with the nutritional information. This way, you don’t need to recalculate everything, which saves a ton of time and headaches!


An Alternative Macros Tracking Method

Another method some people use is to only track their protein intake and monitor their daily calories. If you do this, then for fats and carbs, just pay attention to what you’re eating to make sure you get your essentials (like omega fatty acids and vitamins).

In fact, a lot of advanced lifters do this to ensure muscle hypertrophy without rigorously tracking.

Tips And Common Mistakes With Counting Macros

Keep these 3 tips in mind to set yourself up for macro counting success.

  1. Remember to track everything, even a little “snack.”
  2. Track your food as soon as you eat it, so you don’t forget.
  3. Calories from liquids count!

How To Control Your Body Weight By Counting Macros

We’ll now quickly go through how to adjust your macros and total calorie intake. To do this, we’re going to use the 3,000-calorie example from above.

The calorie needs from the above calculation are known as your maintenance calories. This is the amount you need to eat to maintain your weight.

Basically, your daily calorie intake is equal to the number of calories burned throughout the day. As a result, you maintain the same body composition. If you’re hoping to use macro counting for weight loss, you’ll need to lower your daily intake. If the goal is to build muscle, you’ll want to increase it.

How to Count Macros For Weight Loss

When you want to lose fat and weight, you need to eat fewer calories than you expend. This means your body will grab more fuel from your fat stores, glucose, or muscle (which we don’t want!).

Therefore, when counting macros for weight loss, eat fewer calories than your maintenance calories. Under normal circumstances, you should attempt to cut 300-500 calories for steady weight loss. This will put you in a big enough defect to lose weight while still being moderate enough to maintain muscle mass.

Subtracting the 300 to 500 calories, your daily calories are now 2,500-2,700 calories. We suggest making this cut as small as possible. So if you’re not in a rush, choose to eat 2,700 calories. Without reducing your calories more, you can create an even bigger deficit with simple changes to your workout routine, like adding a few LISS cardio sessions each week.

For your macros, you’ll eat the same amount of fat (100g at 900 calories) and protein (225g at 900 calories). You could alter the fat and protein content, but this isn’t needed under normal circumstances.

Therefore, we use carbs to cause a 300-calorie deficit. Three hundred calories divided by 4 calories is equal to 75 g. of carbs. So the new macro diet becomes:

  • 225 grams of protein
  • 100 grams of fat
  • 225 grams of carbs (300g – 75g)

Macro Counting For Muscle Gain

Now, in order to build muscle and gain strength, you need to add more calories. When it comes to weight gain, the same general rule of 300-500 calories applies, but now we’re using it to create a caloric surplus.

In order to mitigate fat gain and maximize muscle gain, start with 300 calories. This means you now need to eat 3,300 calories.

Again, the fat and protein content can stay the same. This leaves us with raising the number of carbs to add calories. Three hundred calories equal 75 grams of carbs, so the new macro diet for gaining weight is:

  • 225 grams of protein
  • 100 grams of fat
  • 375 grams of carbs (300g + 75g)

Counting Macros: A Summary

Counting macros, particularly when paired with moderate exercise, is an effective way to control your diet while still giving yourself some freedom to occasionally eat unhealthy foods. Also, realize that a time will come when you won’t need to really count macros anymore.

As you become aware of your body and proper food portions, the need to be exact will lessen. Alternatively, if nothing has ever worked for you, counting macros will as it’s merely obeying natural laws. The headache will be worth it in the end!
