BMR Equation for Men:
| From: | To: |
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. It represents the minimum energy required to maintain vital functions such as breathing, circulation, and cell production.
The calculator uses the Mifflin-St Jeor equation for men:
Where:
Explanation: This equation calculates the number of calories your body burns at complete rest, which forms the foundation for determining your daily caloric needs for weight management.
Details: Knowing your BMR is essential for effective weight loss planning. It helps determine your Total Daily Energy Expenditure (TDEE) when combined with your activity level, allowing you to create a caloric deficit for weight loss while ensuring you meet your body's basic energy requirements.
Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120). For accurate results, use your current measurements.
Q1: What's the difference between BMR and TDEE?
A: BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities and is calculated by multiplying BMR by an activity factor.
Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (5+ kg) or every 3-6 months as part of your weight management routine.
Q3: Can BMR change over time?
A: Yes, BMR decreases with age (about 1-2% per decade after age 20) and with weight loss, as smaller bodies require fewer calories to function.
Q4: How accurate is this BMR calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for the general population, with about 80% accuracy for most individuals.
Q5: How should I use my BMR for weight loss?
A: Calculate your TDEE by multiplying BMR by your activity level, then create a caloric deficit of 500-1000 calories per day for safe weight loss of 0.5-1 kg per week.
