What is a Calories Burned Calculator?

Calorie Burned Calculator determines the calories while doing any activity. The activity could be walking, cycling, or running. In the Calculator, state the activity like walking or running. Add the duration you will be doing the activity and your body weight.

The Calculator will calculate the Calories Burned.

How to find Calorie Burned by Distance Calculator?

The calories that need to be burned by running, walking, or cycling.

Mention the activity and the speed at which one is doing the activity. Add the details of the distance covered for the activity and the body weight.

So, the number ofduring the activity depends on various factors. Hence it is not an exact science. The result of this Calculator depends on standardized data regarding the average person. Hence it can only calculate. So the formula used by the Calculator is described further in the article.

If one needs to know how many calories should be taken, maintaining the weight or weight loss. The Calorie Calculator can be used. Mostly the number of calories consumed, burning fewer calories with activities, and Basal Metabolic rate. It determines if a person maintains, loses, or gains weight. So if the number is negative, the individual will lose weight, and if it's positive, the individual will gain weight. In case of more details regarding Basal Metabolism, one can use a BMR calculator.

What factors affect the calories burned?

The calories an individual burns while performing a certain activity depends on various factors. It mostly involves three things. The key factors are Body Mass, the activity period, and the Metabolic Equivalent of a Task It is also called MET.

• Body Mass and duration

The Body Mass of an individual determines how many calories are burned even when the individual is resting. A person largely burns more calories due to fat, muscle, and even height. It is also possible when one is doing ExerciseExercise. The body needs more energy from a person which large body fat compared to a person with less BMI. So if a person weighs 200 pounds burns more calories after running 1 mile than someone who weighs 100 pounds. Provided other conditions remain the same.

The duration of Exercise is another factor affecting the calories burned. So longer a person exercises, the more calories are burned. However, it is not possible with body mass. Because now the Intensity of the exercise matters.

Consider this an example: A person who walks 1 mile in an hour will burn fewer calories than walking 5 miles.

• The Intensity of Exercise

Exercise is another major factor in determining the number of calories burned. So the more intense the Exercise, the more calories are burned. The Intensity of Exercise is measured in different ways. Some of them are more precise.

The Intensity of Exercise is measured using heart rate. Heart rate determines how difficult it is for a person to complete one Exercise.

The higher a person's heart rate while exercising, the more the Intensity and hence more calories are burned. People also have variable resting heart rates and maximum heart rates. Hence, heart rate is not the precise measure of the Intensity of the Exercise. It is because a fit person has a lower heart rate. Also, assuming they have other conditions which could affect the heart rates.

Now a more precise measuring factor of Intensity involves the measurement of oxygen consumed by a person. It is measured while the person is exercising.

Oxygen consumed and Intensity of Exercise is directly proportional. Because as the Intensity of Exercise increases similarly, oxygen consumption also increases.

Unlike the heart rate because it varies depending on various factors. The oxygen needed by a person is closely related to BMI. It makes it clear and creates a standard for Oxygen Consumption. Now again, it is for specific exercises concerning BMI.

Now oxygen consumption is measured in MET. There are many definitions of MET. But the original definition and one used by the Calculator completely depend on oxygen utilization and BMI.

MET

It is a ratio of the rate at which a person spends energy while doing a physical task compared to a reference. So the reference is based on the energy spent by an average person. Even if the person sits quietly, it is around 3.5ml of oxygen. The value is calculated by measuring the MET of a 40-year-old. The person weighs, let's assume, 70 kg. The baseline and MET values indicate the energy spent by an average person at rest. So an activity with a MET value of 2 needs twice an average person's energy at rest. So a MET value of 8 needs eight times more energy.

Now exercises are commonly categorized as light Intensity, modern or vigorous. Higher Intensity, also known as HIIT, has a higher MET rate.

So walking is a low-intensity exercise with a MET of 2.0. Playing table tennis is 5.0MET. Jumping 100 times with the rope is vigorous Exercise, and the MET is 11.

Is anyone interested in buying fat or losing weight? Understanding that exercise intensity affects the fuel type, meaning the carbohydrate, fats, and proteins, is crucial. The body breaks them down and supplies them as energy. Mostly low, the intense Exercise burns fatter. So if a person intends to burn fat, they should stick to low-intensity work out for a brief duration. But as the intensity increases. The body uses protein and carbs instead of fat to provide energy. The body gets energy from proteins, although it happens very less. Mostly the body will take the carbs or fats to burn during intense workouts.

What are the other factors?

The points mentioned above are key factors. It is used in estimating calories burned. Although there are many other factors, such as:

• It affects a person's energy used while resting. As a person grows, they lose out on body mass. It tends to cause a loss in metabolic rate. So as an individual grows, they burn a few calories. Suppose we compared two people with different age groups. The older one burns fewer calories.
  
  
• Body Composition-The muscle needs more energy than fat. So a person with the same height and weight burns more calories if he/she has more muscle.
• Weather-People burn more calories in a warmer environment. Because the higher temperature in the surrounding increase the body temperature. So the body burns more calories instead of making the body warm.
  
  
• Level of fitness- It affects the exercise intensity on an individual level. So a person with a fit shape burns fewer calories than someone with a not-so-fit shape. It is because the person's shape is more efficient; hence, the body uses less energy.
• Diet- A person's diet directly affects their metabolism. A person with low metabolism burns fewer calories than someone with a high metabolism.
• Rest-It is a major factor in determining the number of calories burned in some ways. A person who rests less or sleeps less is more fatigued. So the person exercises less as compared to others. So if a person doesn't rest or sleep well can see a decline in their metabolism. Hence it reduces the number of calories burned.

How to calculate the calories burned?

The calories burned using the Calculator can be calculated with the following formula.

Calories =Time × MET × Body Weight/200

Here time is the unit of minutes and body.

Weight is the unit in kilograms.

Many doctors, dietitians, and studies have been conducted on the calories burned or expended. The Calculator uses data from such studies to calculate the MET. Calculating the calories burned during the duration of an activity performed along with the Body Mass.

The accuracy of the Calculator

The accuracy of the Calorie Calculator is affected by MET. So 1 MET is equal to 1 Calorie per Kg. It is equal to consuming 3.5ml oxygen per Kg of BM per minute.

The formula was derived by considering a single subject. So a person who weighs 70kg at the age of 40. An individual's resting metabolic rate is based on many factors like lean body mass, age, health, and more. So the calculation of a person whose RMR differs from the reference used.

Some studies suggest that 1 MET value is 20-30%of oxygen consumed while resting.

The MET values are considered as the activity is performed at a constant rate.

Now consider this example: Playing tennis for an hour will include taking breaks, resting, chatting, and other. So the activity is based on a small duration. So if the duration is not represented accurately, it will affect the accurate calculation.

Conclusion

A good way to determine an accurate number is for an individual should go to a lab. A lab that measures all the necessary factors needed. Like the oxygen capacity, maximum heart rate, and other things as per their requirement. More often, it needs to be right what the approximate is based on. It is important to understand that MET is used as an Intensity index. So instead of calculating calories for a Specific person. The calories burned may only be accurate once the person shares similar traits with someone whose RMR is used for comparison.
