A Macro Calculator is an online tool that allows you to track and discover your macronutrient intake. Here’s how it works.

What is a macro calculator?

This macro calculator is a comprehensive tool that can work as your dieting companion. After providing some basic information such as your current level of fitness and goal weight, you will get a weekly detailed diet plan based on your macros intake.

Counting macros is a crucial part of flexible dieting, and your success will be determined mainly by your macro calculation. A poorly calculated macro ratio leads to loss of muscle mass and a lack of progress in fat loss goals. It can even make you gain weight! But with the right calculator and macro calculator tips, everything will become much easier.

The macro calculator, also known as the ‘free macro calculator,’ was created to show you what your correct calorie intake and macro breakdown should look like based on your goals. It’s a diet calculator that allows you to find the right way to eat for yourself. So let’s get into it!

If you’re new to the whole Macro diet and flexible dieting world, you may be wondering where I start. How do I calculate my Macros? What are ideal body macro ratios?


What are Macronutrients (Macros)?

Main food groups macronutrients

Macronutrients or “macros” are the building blocks of nutrition. You probably know them better as carbohydrates, protein, and fat. Macros are the components of food that provide us with calories (or energy).

Macronutrients are the 3 main types of food energy that your body needs in the greatest amount. They include protein, carbohydrates, and fats.

“Body Composition” macronutrient calculator: how to calculate macronutrients the right way?

The most important thing to remember when calculating your macronutrients is that this isn’t an exact science. You’ll need to use a calculator and experiment with various amounts until you find what works best for you.

For example, if you’re starting out with a weight loss goal, it’s generally recommended that you start at 20% protein and 50% carbohydrates, while only eating as much fat as necessary to feel full (the rest of your calories will come from protein and carbs). If this ratio doesn’t work for you, you can increase or decrease it until it does.

For example:

If 20% protein isn’t enough for you and causes hunger pangs, increase the amount of protein in your diet by 5-10%. If 50% carbohydrates make you feel bloated or tired after eating them, lower the amount by 5-10% until they’re no longer causing side effects.

The short answer is: You need to create a diet that fits your lifestyle and your body type. The long answer involves getting into the details of macronutrient ratios, counting calories, and knowing how much protein, carbs, and fat you need.

Macronutrients are the main components of food that provide energy to our bodies. They are carbohydrates, proteins and fats. The ideal percentage of each depends on your goals and activity level. For example, if you’re active, you need more carbs than someone who doesn’t exercise as often. Or if you’re trying to lose weight, then you might want to increase your protein intake while reducing fat intake.

Why are macronutrients essential?

Macro is short for macronutrients. A macronutrient is one of three nutrients we consume in our diet: Protein, carbohydrates, and fats. Each macro has a specific caloric value per gram:

Carbohydrates = 4 calories/gram

Protein = 4 calories/gram

Fats = 9 calories/gram

“Fat Loss” macronutrient calculator

If you’re trying to lose weight, macronutrient calculator will help you find the right amount of protein, carbohydrate, and fat.

The reason is that each macro will affect your body differently. If you’re looking to lose fat, you will want to eat more protein and fewer fats and carbohydrates. If you’re looking to gain muscle, you will want to eat more protein, carbohydrates, and fewer fats. So how do we calculate what the right amount of macros should be for you? First, we need to figure out your maintenance calories (the amount of calories required to maintain your current weight). We then multiply that number by a percentage based on your goal (fat loss or muscle gain) to get

Macronutrients serve as your body’s fuel to keep you moving throughout the day. Each macronutrient has a different role to play in your body:

Protein contains amino acids, which build muscle, other tissues, enzymes, and hormones. Protein also helps repair muscles after exercise and aids in recovery.

Carbohydrates provide glucose, which is used by cells for energy. Glucose is essential for fueling the brain and central nervous system.

Fat provides essential fatty acids and fat-soluble vitamins A, D, E, and K. Fatty acids help support healthy skin and hair, insulate your body and protect vital organs from damage.

“Healthy Food” macronutrient calculator

The macronutrient calculator is a tool that allows you to determine how many calories you need to consume, and what foods you need to eat, in order to reach your desired weight.

The macronutrient calculator is based on the following principles:

A calorie deficit is needed in order to lose weight. This means burning more calories than you take in through food and drink.

Macronutrients are the nutrients required by the body in large amounts. These include protein, carbohydrates, and fat. Carbohydrates provide energy for the body and are found in starchy foods like bread, pasta, rice and potatoes. Protein helps build muscle mass and repair tissues in the body.

Fat provides energy too but also has many other functions such as storing vitamins A, D, E and K, as well as being a source of essential fatty acids (omega-3 and omega-6).

“Lose Weight” macronutrient calculator

The Lose Weight Calculator takes into account all three macronutrients and allows you to choose how many calories you want to consume for each one. This will help you determine how much of each type of food you need per day in order to meet your calorie goal.

For example, if you are trying to lose weight and you want to take in 2,000 calories per day, we would recommend having 40 percent carbs (800 calories), 30 percent protein (600 calories), and 30 percent fat (600 calories).

Counting macros helps keep track of how many grams of protein, carbs and fat you should eat each day. This ensures that your diet provides enough nutrients for your body’s daily needs while also keeping your calorie intake within a healthy range for weight loss or maintenance (depending on your goals).

The following calculator will help you determine the number of calories and grams of protein, carbs, and fat you should aim for each day. It also gives you an idea of how much water you should drink each day!

Healthy protein

Healthy proteins are natural substances comprised of amino acids and are among the types of macronutrients. Amino acids are essential to a person’s health, and there are specific amino acids that can just be gotten through diet. These are typically called “crucial amino acids” and are obtained by humans and various other animals through healthy protein intake.

There are many sources of protein, both animal (meat, dairy products, and so on) and plant-based (beans, vegetables, nuts, seeds, etc.). Likewise, healthy protein supplements are often utilized by people trying to construct muscle mass. Although healthy protein is a necessary part of the human diet plan, just like many points, moderation is essential. There are additionally much healthier and unhealthier proteins.

Healthy proteins consist of:

  • Soy.
  • Beans.
  • Nuts.
  • Fish.
  • Skinless fowl.
  • Lean beef.
  • Pork.
  • Low-fat dairy products.

Unhealthier proteins consist of:

  • Fried meats.
  • Processed meats (deli meats, sausages, fast-food hamburgers, etc.).
  • High sugar yogurts.
  • Refined healthy protein bars.
  • Numerous cheeses.

Carbs (Carbohydrates)

Carbohydrates, commonly referred to as just “carbs,” are substances that are typically categorized as sugar, starch, or fiber. Sugar is the simplest type of carb, while starch and fiber are ex carbohydrates. Carbs are commonly additionally categorized based on the number of saccharides that rise them: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Monosaccharides and disaccharides are usually referred to as “straightforward carbohydrates,” while oligosaccharides and polysaccharides are “complex carbohydrates.”

Glucose is a monosaccharide and is just one of the crucial sources of power for humans and other pets. Numerous microorganisms, including people, can not quickly metabolize polysaccharides such as cellulose. However, it can still provide them with critical dietary fibers, which assist with digestion.

Way too many carbohydrates in the form of sugar (typical in processed foods) can have adverse health impacts. Yet, more intricate carbohydrates (from veggies, fruits, whole grains, vegetables, and so on), specifically those that provide dietary fibers, are advantageous and needed for the human body.

Fats are molecules that are comprised primarily of carbon as well as hydrogen atoms. Typical instances consist of cholesterol, phospholipids, and also triglycerides. Although fats are generally viewed as unhealthy in the context of nourishment, they have both structural and metabolic functions and are a needed part of the human diet regimen. They are also highly energy thick and have the most reliable energy storage space.

Fats are commonly categorized based on the bonding of carbon atoms in terms of dietary fats considered referenced fats include several types of fat:

Generally, saturated and trans fats are considered harmful fats, while monounsaturated, polyunsaturated, and omega-3 fatty acids are considered much healthier and much better fat resources for the body.

Basic recommendations from the Dietary Guidelines for Americans for 2015-2020 include entirely avoiding trans fats, limiting saturated fat consumption to comprise less than 10% of calories consumed daily, and preferably changing saturated fats in the diet regimen with monounsaturated and also polyunsaturated fats.

Daily Calorie Demands

The variety of calories an individual requires to consume daily is mainly based upon various elements consisting of height, weight, age, and task degree, together with whether the individual intends to keep, lose or gain weight. The values calculated are based upon 2 formulas for estimating the Basal Metabolic Rate (BMR) or relaxing daily energy expense (RDEE) of a person. Once the BMR or RDEE is determined, they are then increased by an activity factor to estimate day-to-day calorie demands.

The Mifflin-St Jeor Formula is a commonly adopted equation that calculates BMR mainly based on physical attributes such as body weight and height. The Katch-McArdle Formula calculates RDEE, which takes lean body mass into account. The Katch-McArdle Solution can be much more accurate for leaner people and their body fat percentage.

Based on the above aspects, an average individual might need to consume anywhere from 1600-to 3000 calories a day. The referrals are usually higher for guys (2000-3000) than women (1600-2400), and a raised task level requires more calories, while a less active individual would undoubtedly call for less.

As carbohydrates, proteins, and fats give virtually the whole energy demands of the human body, their everyday needs can be calculated based on the daily caloric requirement. The values returned by the macro calculator are an estimate based upon standards and standards given by several institutions, such as the American Dietetic Association, Centers for Condition Control and Avoidance, World Health Organization, and much more.

What is Macro Calculator?

A macro calculator is a simple tool that helps you find out the right amount of calories and macronutrients (like proteins, fats, and carbs) to eat daily.

The calculator is based on your age, height, current weight, and activity level.

Whether you want to lose weight or gain muscle mass, you can use this calculator or be in good shape. This tool will help you determine the ideal number of calories you should consume each day, considering your goal. It also calculates the number of calories burned per day based on an estimate of your metabolic rate.

Flexible dieters design the macro calculator. If It Fits Your Macros (IIFYM) is another name for flexible diet programs. The full kind of IIFYM is if it fits your macros. Macros are brief for macronutrients, as well as they are defined as substratum made use of to generate power in the body. Carbohydrates, fats, and healthy proteins are macronutrients. The total caloric amount for food is determined by adding all the macronutrient quantities.

What Are The Right Macros For You?

Every person has a different metabolic rate and will lose or gain weight at different rates depending on how many calories they consume. In order to lose weight, you need to be in a caloric deficit; to gain weight. It would help if you were in a caloric surplus.

The ideal macros for you depend on your goals and body type. If you want to reduce fat, aim for 25% protein, 25% carbs, and 50% fats. If you want to increase muscle mass, aim for 40% protein, 40% carbs, and 20% fat.

While these are general guidelines, the best way to get an accurate calculation is by consulting a medical professional or fitness coach who can help you set your macros based on your goals and body type.

The right macros are based upon your individual Total Daily Energy Expenditure (TDEE).

Our macro calculator defaults at the best macro ratio that’s proven to work for the most number of individuals. You ought to attain your goals by making use of the default setup. However, there is nothing incorrect with adjusting this ratio if needed. Perhaps you’re an endomorph and do far better with fewer carbs. Or, probably only have one kidney and need to consume much less protein. You can readjust the macros to ideal degrees for you directly with a bit of math, described thoroughly here.

How to Determine the Right Daily Protein Amount?

Setting healthy protein to Modest readjusts the ratio to.65 grams per pound of body weight. This is appropriate for less active people or people with higher body fat portions.

High is suitable for active people who do moderate strength training and have an ordinary body fat percentage.

The maximum will undoubtedly be ready to 1 gram/ lb. This is ideal for those intending to acquire weight/muscle mass and do intense training.

Using the Macro Calculator to Measure Daily Fat Quantity.

Fats are evaluated by 30% of everyday energy expenditure. This is a healthy and balanced moderate amount that most people succeed with and is based on recommendations by nutritional guidelines. When selecting foods that contain fat, concentrate on obtaining predominately healthy and balanced fats as part of that 30%.

Using The Macro Calculator To Measure Daily Carb Quantity.

After calculating protein and fat, the calculator appoints the remainder of your calories as carbohydrates. This generally causes a modest amount of carbs in the variety suggested for many people. Carbs fuel your body and exercise and are the body’s preferred energy resource. Many individuals originating from the “low carb” type of weight loss might feel like this calculator measures carbohydrates on the high side. Nevertheless, according to valued nutritional guidelines, this is a moderate quantity of carbs. The notion that sugars create weight gain or avoid weight loss when eaten about your TDEE has been exposed.

When should you calculate your macronutrient consumption?

When you are slim yet want to be slimmer:

If you determine your macronutrient intake, you can track what you eat and go down a couple of pounds of fat.

A due date to fulfill:

Whether it’s an image shoot or any friend’s wedding and also you intend to reduce weight, however, you have much less time on your hand. You can use the macro calculator to change your diet according to your objective weight.

It’s difficult to control your appetite:

The cravings for chips or chocolate ice cream can substantially damage your diet plan and, side by side, raise your weight. This way, you cannot take in the essential macronutrients and balance them. If you calculate your macronutrient intake, you can intend your meals and steer clear of these food cravings, reducing your hunger.

The idea of just how much healthy protein to take in isn’t clear:

Most individuals aren’t well aware of how much protein to consume and have the wrong idea. To suggest how much healthy protein to eat, you must utilize a macro calculator as individuals often tend to take in carbohydrates and fats more than proteins.

When you are a macronutrient veteran.

Being aware of which diet you need to eat with the limit of each macronutrient, you have understood that balancing your lifestyle according to healthy consumption makes using a macro calculator ineffective.

Why can’t I count calories?

Tracking calories while focusing on healthy food sources and the general equilibrium can work! As long as you remain in a good shortage or surplus, your weight will gradually alter. Nevertheless, counting macros helps focus on each macronutrient, which can be conveniently tailored around specific training designs and goals. Whatever you do, do not merely reduce your calories significantly. Count them and assume that’s the be-all, end-all option. For many people, solely taking a calorie-conscious technique may lead to the same old yo-yo diet catch, where they feel fatigued, denied, and diminished. I’m sure that wasn’t your plan when trying to tidy up your nourishment.

Do I need to be 100% accurate?

When it pertains to calories, complete accuracy is a misconception. So don’t sweat it. Obtaining within 10 grams of your target healthy protein and carbohydrate intake is sufficient. This will undoubtedly enable versatility and a much-needed remedy for overanalyzing your intake. If, for example, your goal is 250 grams of carbs, anywhere within 240-260 grams is OK. The deviation is an adjustment of 40 calories at most in either direction. This isn’t anything to fret about.

On the other hand, fat is more significant than twice as calorie-dense as healthy protein and carbs, containing 9 calories per gram versus 4. To limit excess calorie intake, maintain your fat intake within 5 grams of your goal. If, for example, your fat goal is 60 grams, anywhere between 55-65 grams will be enough. This, too, will result in just a minor difference of 45 calories.

How should I track my macros?

Track your macros in any way that helps you. Applications can be convenient, most of which enable you to track your consumption on the go. Most have a high nutrient food database, which will help you find any food. Some even include a barcode scanner, assisting you in guaranteeing every meal you consume is trackable.

Fresh vegan food

Should I track my Vegetables?

Many vegetables consist of really little in the means of calories (leaving out starchy veggies like peas, potatoes, and corn), so many individuals support including them in your macros. However, they still have calories and carbs, so there’s a debate either way. My referral consists of a handful of non-starchy veggies at a minimum of three dishes.

Don’t count that quantity, and continually do your best to get it at every meal. If you pick to have more than one serving at a dish, count the carbs from the servings to keep calories in check. For instance, 1 cup of pasta squash has 7 grams of carbohydrates. If you plan to have 3 portions at one dish, count carbs from the second and 3rd cups. In this case, you would undoubtedly count the squash as 14 grams of carbohydrates for the meal.

Main macronutrient food groups

Should my macros coincide daily?

This is where you get points as an individual. Many experts argue that macros are the same, regardless of the day’s training, to keep food preparation and intake simple. Sure, this might save you a couple of minutes, but on the other hand, your caloric requirements are most likely to vary on a day of rest than on a hard training day.

Does it take that much more time to consider 100 grams of wild rice? Most likely not. You probably do not need various macro splits for every day of the week, but I advise setting apart between a training day and an off day. On days when you don’t educate, you will certainly not have as great a demand for carbs since you’re using up much fewer calories. Cutting back on carbohydrates will undoubtedly assist in more appropriately straightening your nourishment and training, mainly when weight reduction is the goal. I recommend cutting down carbohydrates by 30-50 percent while maintaining healthy protein and fats constant.


  • Carbohydrates 250 grams.
  • Protein 185 grams.
  • Fat 70 grams.
  • Calories 2,370.


  • Carbohydrates 125 grams.
  • Protein 185 grams.
  • Fat 70 grams.
  • Calories 1,870.

After Fulfilling my macros, should I fill the remaining calories?

This happens at all times. Say your everyday calorie objective is 2,500 calories and hit your macros with 110 calories. Don’t worry about “filling out” those extra calories. Focus on the macros, and the calories will certainly level in time. Each day’s food options will undoubtedly influence the complete calories eaten, but this distinction differs day by day. For example, taking in an offering of olive oil will provide you with 15 grams of fat; nonetheless, taking in 15 grams of fat from the peanut butter will certainly likewise give you trace amounts of healthy protein and carbohydrates and 80 added calories.

This calorie difference usually functions itself out over time when including a selection of food options into your day. Tomorrow’s mild shortage will be smoothed over at work by tomorrow’s mild unwanted. There’s no need to “complete” continuing to be calories. If you discover you’re somewhat above your predetermined calorie goal, the same applies.

Among the significant rewards of following an If It Fits Your Macro (IIFYM) strategy is that you can eat a  combination of nutrients and your favorite deals. So practically, you can indulge daily in a slick of cake or an item of chocolate. Nevertheless, it can be a nice mental breather not to track macros for a meal every so often. For ideal development, particularly during a weight-loss stage, limiting these “free meals” to when every few weeks or once a month. That might appear limiting, yet remember that you can consume anything you intend to each day, as long as you watch. That counts for lots!

Key and a note on a wooden table - It's Up To You

The rest is up to you

Despite whether you’re trying to shed or gain weight, your objective must be to target no higher than an adjustment in weight of 1 percent of your body weight per week to optimize the change to your body composition.

This implies that a 155-pound female focused on weight loss need to aim for no greater than 1.5 extra pounds weekly, to decrease the threat of muscle mass loss. A 170-pound male attempting to gain weight must similarly aim for no greater than 1.7 extra pounds each week to minimize fat gain.

With these details in mind, make adjustments of 300-500 calories as soon as your weight management has been delayed to keep you on track for your goal weight.  Most of the time, the best approach is to keep protein consumption the same (if sufficient) and adjust carbs and fat to help you tweak your numbers.

​​IIFYM isn’t a set-in-stone system like Atkins or Weight Watchers. It’s an individual approach that’s exploded in the online age, and as such, there are numerous methods to approach it as there are foods in the store.

Sure, you can slip into analysis paralysis. However, this method is meant to be satisfying! Remember that, and keep in mind to be sincere and track consistently, and you’re set for success.
