Here’s How Many Calories You Naturally Burn in a Day 

The number of calories you naturally burn in a day, known as your basal metabolic rate (BMR), depends on various factors including your age, gender, weight, height, and activity level. 

Harris-Benedict Equation: One common method to estimate BMR is using the Harris-Benedict equation, which takes into account your gender, age, weight, and height. Here are the formulas for calculating BMR for adults: 


Bruises and Minor Bumps: Mifflin-St Jeor Equation: Another commonly used equation is the Mifflin-St Jeor equation, which is considered to be more accurate for estimating BMR. The formulas are as follows: – For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 – For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161– Elevate the injured limb if possible to further reduce swelling.

Activity Level: Once you have calculated your BMR, you can estimate your total daily calorie needs by multiplying your BMR by an activity factor that represents your typical activity level: – Sedentary (little to no exercise): BMR × 1.2 – Lightly active (light exercise/sports 1-3 days a week): BMR × 1.375 – Moderately active (moderate exercise/sports 3-5 days a week): BMR × 1.55

ake into account your personal information and activity level to estimate the number of calories you burn in a day. These devices typically use algorithms similar to the ones mentioned above to calculate BMR and total daily calorie expenditure. 

Keep in mind that these equations provide estimates, and individual calorie needs may vary. Additionally, factors such as muscle mass, body composition, and metabolic health can also influence calorie expenditure. 

If you're trying to manage your weight or make changes to your diet and exercise routine, it's helpful to track your calorie intake and expenditure to ensure you're meeting your goals. 

Activity Level: Physical activity, including exercise and non-exercise activities like walking, cleaning, and standing, also contributes to your total daily calorie expenditure. The more active you are, the more calories you burn above your BMR.
