BMR Calculator
BMR Calculator
Calculate your Basal Metabolic Rate (BMR) to estimate how many calories your body burns at rest.
BMR Calculator FAQs
1. What does BMR stand for?
BMR stands for Basal Metabolic Rate. It represents the minimum amount of energy your body needs to perform basic life-supporting functions while at rest.
2. How many calories does the average person burn at rest?
Average BMR values are typically around 1,400–1,800 calories per day for women and 1,600–2,000 calories per day for men, depending on age, height, weight, and body composition.
3. Which formula is commonly used to calculate BMR?
Many calculators use the Mifflin-St Jeor Equation because research has shown it provides reliable BMR estimates for most adults.
4. Does muscle mass affect BMR?
Yes. Muscle tissue burns more calories than fat tissue, so people with higher muscle mass usually have a higher BMR.
5. Does BMR decrease with age?
Yes. BMR generally decreases with age because muscle mass tends to decline and metabolism naturally slows over time.
6. Is BMR different for men and women?
Yes. Men often have a higher BMR than women because they generally have more muscle mass and lower body fat percentage.
7. Can dieting lower BMR?
Very low-calorie diets may temporarily reduce BMR because the body tries to conserve energy during calorie restriction.
8. Is BMR the same as TDEE?
No. BMR measures calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes physical activity, exercise, and digestion.
