Calories Burned by Existing Calculator

The number of calories burned by existing, also known as the Resting Metabolic Rate (RMR), depends on various factors such as age, weight, height, gender, and body composition. On average, a sedentary person may burn around 1,200 to 2,400 calories per day. However, individual variations can cause these values to vary significantly.

How many calories does my metabolism burn a day?

The number of calories your metabolism burns in a day depends on various factors such as your age, weight, height, gender, body composition, and activity level. The Resting Metabolic Rate (RMR) is the number of calories your body burns at rest, just to maintain essential bodily functions like breathing, circulating blood, and maintaining body temperature.

As an estimate, you can use the Harris-Benedict equation to calculate your Basal Metabolic Rate (BMR), which is similar to RMR but includes a slight adjustment for activity level:

For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

After obtaining your BMR, you can multiply it by an activity factor to estimate your total daily caloric needs, which takes into account your physical activity level:

Sedentary (little to no exercise): BMR x 1.2 Lightly active (light exercise/sports 1-3 days/week): BMR x 1.375 Moderately active (moderate exercise/sports 3-5 days/week): BMR x 1.55 Very active (hard exercise/sports 6-7 days/week): BMR x 1.725 Extra active (very hard exercise/sports and a physical job): BMR x 1.9

How many calories do I burn just living?

The number of calories you burn just by living, also known as Resting Metabolic Rate (RMR) or Basal Metabolic Rate (BMR), varies depending on your age, weight, height, gender, and body composition. It represents the energy your body needs to maintain essential bodily functions at rest, such as breathing, circulating blood, and maintaining body temperature.

To estimate your RMR or BMR, you can use the Harris-Benedict equation:

For men: RMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) For women: RMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

For example, if you are a 30-year-old woman, weighing 70 kg and measuring 165 cm tall, your estimated RMR would be:

RMR = 447.593 + (9.247 x 70) + (3.098 x 165) – (4.330 x 30) = 1367 calories per day

This means that, just by living and performing essential bodily functions, your body would burn approximately 1367 calories per day. Keep in mind that this is only an estimate, and actual calorie needs may vary based on individual factors and activity level. For a more accurate assessment, consider consulting a registered dietitian or healthcare professional.
