This formula has since been widely used by nutritionists, dietitians, and fitness professionals to help individuals achieve their health goals.
Using the Harris-Benedict formula, I personally calculated my daily caloric needs and was able to enjoy a flexible diet while ensuring that I consumed the appropriate number of calories.
As a result, I was able to shed a significant amount of body fat.
The formula takes into account an individual’s weight, height, age, and sex to determine their basal metabolic rate (BMR), or the number of calories burned at rest. The formula then factors in the individual’s activity level to determine their TDEE (Total Daily Energy Expenditure).
It is important to note that the Harris-Benedict Calculator provides an estimate and is not a definitive measurement of an individual’s caloric needs. However as a starting point it gives you the basic knowledge to start understanding your body.
As always, it is recommended that individuals consult with a healthcare professional or registered dietitian before making any significant changes to their diet or exercise routine.

Calorie Calculator: How to Easily Determine Your Daily Caloric Intake
If you’re looking to maintain or lose weight, it’s important to know how many calories your body needs to function properly. Your daily calorie intake depends on various factors such as your age, gender, height, weight, and activity level. Calculating your daily calorie needs can be a daunting task, but fortunately, there are many calorie calculators available online that can help you determine your daily caloric needs.
A calorie calculator is a tool that estimates the number of calories your body needs to maintain your current weight, lose weight, or gain weight. These calculators take into account your age, gender, height, weight, and activity level to provide an estimate of your daily caloric needs. By knowing your daily calorie needs, you can adjust your diet and exercise routine to achieve your weight loss or weight gain goals.
There are many calorie calculators available online, including those provided by Mayo Clinic, Calculator.net, and Healthline. These calculators can give you a good estimate of your daily caloric needs, but keep in mind that they are only estimates. Your actual calorie needs may vary based on your individual metabolism and other factors. It’s always a good idea to consult with a healthcare professional or registered dietitian to determine your specific daily calorie needs.
Understanding Calories
Before we dive into the specifics of calculating your daily calorie needs, it’s important to understand what calories actually are.
Calories are a unit of measurement for energy, specifically the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. When we talk about calories in relation to food, we’re referring to the amount of energy that food provides to our bodies.
Our bodies need calories to function properly. We use them to breathe, move, and perform all of the other activities that keep us alive. However, consuming too many calories can lead to weight gain, while consuming too few can lead to weight loss.
It’s important to note that not all calories are created equal. Different types of food provide different amounts of energy, and some types of food are more nutrient-dense than others. For example, a 100-calorie serving of broccoli provides a lot more vitamins and minerals than a 100-calorie serving of soda.
Understanding how many calories your body needs each day can be a helpful tool in maintaining a healthy weight. In the next section, we’ll go over how to calculate your daily calorie needs using a calorie calculator.
Determining Your Basal Metabolic Rate
To determine your daily calorie needs, you first need to calculate your Basal Metabolic Rate (BMR). This is the number of calories your body burns at rest, just to keep your vital organs functioning. Once you have calculated your BMR, you can then factor in your activity level to determine your Total Daily Energy Expenditure (TDEE), which is the total number of calories your body burns in a day.
Age
Your age is an important factor in calculating your BMR. As you age, your metabolism naturally slows down, which means you burn fewer calories at rest. This is why it’s important to adjust your calorie intake as you get older. The formula for calculating BMR takes into account your age in years.
Gender
Gender is another important factor in calculating BMR. Men generally have a higher BMR than women because they generally have more muscle mass and less body fat. The formula for calculating BMR is different for men and women.
Weight
Your weight is also a key factor in calculating your BMR. The more you weigh, the more calories you burn at rest. The formula for calculating BMR takes into account your weight in kilograms.
Height
Your height is also a factor in calculating your BMR. Taller people generally have a higher BMR than shorter people because they have more surface area and therefore more heat loss. The formula for calculating BMR takes into account your height in centimeters.
By taking into account your age, gender, weight, and height, you can calculate your BMR using a BMR calculator like the one provided by Bodybuilding.com. Once you have your BMR, you can then factor in your activity level to determine your TDEE and adjust your calorie intake accordingly.

Calculating Your Total Daily Energy Expenditure
If you’re looking to maintain or lose weight, it’s important to know how many calories your body burns each day. This number is known as your Total Daily Energy Expenditure (TDEE), and it takes into account your Basal Metabolic Rate (BMR), Physical Activity Level (PAL), and the Thermic Effect of Food (TEF).
Physical Activity Level: How to Work Out Daily Calories
Your PAL is determined by your level of physical activity throughout the day. It ranges from sedentary (little or no exercise) to very active (intense exercise or physical labor). To determine your PAL, you can use the following table:
Activity Level | Description | Example |
---|---|---|
Sedentary | Little or no exercise | Desk job, watching TV |
Lightly Active | Light exercise or sports 1-3 days a week | Walking, housework |
Moderately Active | Moderate exercise or sports 3-5 days a week | Jogging, cycling |
Very Active | Intense exercise or sports 6-7 days a week | Crossfit, marathon training |
Extremely Active | Intense daily exercise or sports and physical job | Professional athlete, construction worker |
Once you’ve determined your activity level, you can use a TDEE calculator, like the one found at tdeecalculator.net, to estimate your daily calorie needs.
Thermic Effect of Food
The Thermic Effect of Food (TEF) is the energy required to digest, absorb, and metabolize the food you eat. It accounts for approximately 10% of your TDEE. This means that if your TDEE is 2000 calories, your TEF would be around 200 calories.
To maximize your TEF, focus on eating whole foods that are high in protein and fiber. These foods require more energy to digest and can help boost your metabolism.
By calculating your TDEE and taking into account your PAL and TEF, you can determine how many calories you need to maintain, lose, or gain weight. It’s important to remember that these are just estimates, and your actual calorie needs may vary based on a variety of factors, including age, gender, and genetics.
Creating a Calorie Deficit for Weight Loss
If you’re looking to lose weight, creating a calorie deficit is essential. A calorie deficit occurs when you consume fewer calories than your body needs to maintain its current weight. This forces your body to use stored fat for energy, resulting in weight loss. However, it’s important to create a calorie deficit in a safe and sustainable manner.
Safe Calorie Deficit Levels
It’s important to create a calorie deficit that is safe and sustainable. A safe calorie deficit is generally considered to be 500-1000 calories per day, which can lead to a weight loss of 1-2 pounds per week. However, it’s important not to create too large of a calorie deficit, as this can lead to muscle loss, a slower metabolism, and other negative health effects.
Impact of Calorie Deficit on Metabolism
Creating a calorie deficit can have an impact on your metabolism. When you consume fewer calories than your body needs, your metabolism slows down to conserve energy. This can make it harder to lose weight over time, as your body becomes more efficient at using the calories you consume.
To combat this, it’s important to incorporate strength training into your exercise routine. Strength training can help to build and maintain muscle mass, which can help to keep your metabolism high. Additionally, make sure to eat enough protein, as this can also help to preserve muscle mass.
Overall, creating a calorie deficit is an effective way to lose weight. However, it’s important to do so in a safe and sustainable manner. By creating a moderate calorie deficit and incorporating strength training into your routine, you can lose weight while maintaining your muscle mass and metabolism.
Creating a Calorie Surplus for Weight Gain
If you want to gain weight, you need to create a calorie surplus. This means that you need to consume more calories than you burn. The calorie surplus will allow your body to build muscle and gain weight.
Safe Calorie Surplus Levels
It is important to create a calorie surplus, but it is also important to do it safely. You don’t want to gain too much weight too quickly, as this can be unhealthy. A safe calorie surplus level is around 250-500 calories per day. This will allow you to gain weight slowly and steadily.
If you are not sure how many calories you need to consume to create a calorie surplus, you can use a calorie calculator. The calculator will take into account your age, gender, weight, height, and activity level to determine how many calories you need to consume to create a calorie surplus.
Impact of Calorie Surplus on Metabolism
Creating a calorie surplus can have an impact on your metabolism. When you consume more calories than you burn, your body will store the excess calories as fat. This can lead to weight gain, but it can also slow down your metabolism.
To prevent your metabolism from slowing down, it is important to continue exercising while creating a calorie surplus. This will help you build muscle and increase your metabolism. It is also important to eat a balanced diet that includes plenty of protein, carbohydrates, and healthy fats.
In summary, creating a calorie surplus is essential for weight gain, but it is important to do it safely. Aim for a calorie surplus of around 250-500 calories per day and continue to exercise and eat a balanced diet to prevent your metabolism from slowing down.
Using a Calorie Calculator
If you are looking to work out your daily calorie intake, a calorie calculator can be a useful tool. Calorie calculators use various factors such as age, height, weight, sex, and activity level to estimate the number of calories your body needs to maintain your current weight.
To use a calorie calculator, you will need to input your personal information and activity level. Some calculators may also ask for additional information such as your body fat percentage or goal weight. Once you have entered all the necessary information, the calculator will provide an estimate of your daily calorie needs.
Keep in mind that calorie calculators provide an estimate and are not 100% accurate. They are a helpful tool to give you an idea of your daily calorie needs, but it is important to listen to your body and adjust your calorie intake accordingly.
It is also important to note that calorie needs can vary depending on individual factors such as metabolism, genetics, and medical conditions. If you have any concerns about your calorie intake or weight, it is always best to consult a healthcare professional.
In addition to estimating your daily calorie needs, some calorie calculators may also provide guidelines for gaining or losing weight. If you are looking to lose weight, the calculator may provide a recommended daily calorie intake for weight loss. If you are looking to gain weight, the calculator may provide a recommended daily calorie intake for weight gain.
Overall, using a calorie calculator can be a helpful tool in working out your daily calorie needs. Remember to use it as a guide and adjust your calorie intake based on your body’s needs.

How to Workout Your Daily Calories with the Harris-Benedict Calculator
To use the Harris-Benedict Calculator to work out your calories, follow these steps:
Determine your BMR. Use the following formulas, depending on your sex:
For men: BMR = 88.36 + (13.4 x weight in kg) + (4.8 x height in cm) – (5.7 x age in years)
For women: BMR = 447.6 + (9.2 x weight in kg) + (3.1 x height in cm) – (4.3 x age in years)
Determine your activity level. Multiply your BMR by the appropriate activity factor:
Sedentary (little or no exercise): BMR x 1.2
Lightly active (light exercise or sports 1-3 days per week): BMR x 1.375
Moderately active (moderate exercise or sports 3-5 days per week): BMR x 1.55
Very active (hard exercise or sports 6-7 days per week): BMR x 1.725
Extra active (very hard exercise or sports, physical job or training twice a day): BMR x 1.9
Add your BMR and activity factor together to determine your TDEE. Then once you have your TDEE, you can use this to determine roughly how many calories your body needs to be consuming in a day to maintain your current weight or lose weight. I personally ate 500 calories under my needed TDEE calorie amount.
Use MyFitnessPal for How to Work Out Daily Calories
Once you have determined your TDEE using the Harris-Benedict Calculator, you can use this information in the MyFitnessPal app to track your calories and macros.
First, go to the “Goals” section of the app and input your TDEE as your daily calorie goal. This goal will be the number of calories you need to consume to maintain your current weight.
If you want to lose weight, you will need to create a calorie deficit. To do this, you can subtract 500-1000 calories from your TDEE to determine your daily calorie goal for weight loss. For example, if your TDEE is 2000 calories, you could aim for a daily calorie goal of 1500-2000 calories to lose weight.
If your body needs 2000 calories a day and you only eat 1500 calories a day, it will take the other 500 calories from your fat storages (body fat). This will allow you to lose weight.
Once you have set your daily calorie goal in MyFitnessPal, you can begin tracking your food intake. I recommend buying a food scale from Amazon or somewhere convenient to accurately track your portion sizes.
The MyFitnessPal app has a vast food database, including restaurant meals, and you can also scan barcodes or enter nutritional information manually for foods that are not in the database. You can also create custom recipes and meals to make tracking easier.
In addition to tracking your calories, MyFitnessPal also allows you to track your macros. This is useful if you’re wanting to understand nutrition more in-depth. Understanding the use of Carbs, Fats and Proteins is valuable for long term health
Tracking your macros in MyFitnessPal can be incredibly helpful when trying to lose weight. By ensuring that you are getting the proper balance of macronutrients, you can feel fuller for longer and avoid overeating. Additionally you can get the flexibility to go out with friends for food and still hold yourself accountable to your daily calorie goal.
