How Many Calories Do You Burn Just Being Alive

How Many Calories Do You Burn Just Being Alive?

The number of calories you burn just being alive is known as your basal metabolic rate (BMR). Your BMR accounts for about 60-75% of your daily calorie expenditure. This means that even if you don’t do any physical activity, you’ll still burn a significant number of calories just by performing basic bodily functions, such as breathing, digesting food, and circulating blood.

Factors That Affect Your BMR

There are a number of factors that affect your BMR, including:

  • Age: Your BMR decreases as you get older.
  • Sex: Men generally have a higher BMR than women.
  • Height: Taller people generally have a higher BMR than shorter people.
  • Weight: Heavier people generally have a higher BMR than lighter people.
  • Body composition: People with more muscle mass generally have a higher BMR than people with more fat mass.

How to Calculate Your BMR

There are a number of different formulas that can be used to calculate your BMR. One of the most common formulas is the Harris-Benedict formula:

For men: BMR = 66.47 + (13.75 x weight in kg) + (5.003 x height in cm) – (6.755 x age in years)

For women: BMR = 655.1 + (9.563 x weight in kg) + (1.850 x height in cm) – (4.676 x age in years)

Once you’ve calculated your BMR, you can use it to estimate how many calories you need to eat each day to maintain your current weight. To lose weight, you’ll need to create a calorie deficit by eating fewer calories than you burn.

Conclusion

Your BMR is an important factor to consider when trying to lose weight or maintain a healthy weight. By understanding how your BMR is calculated and what factors affect it, you can make informed decisions about your diet and exercise plan.
