BMR Calculator
Calculate Basal Metabolic Rate and daily resting energy expenditure
How to Use This Calculator
- Select your biological Gender from the drop-down menu.
- Enter your current age in years into the Age field.
- Provide your total body weight in kilograms in Weight (kg).
- Input your standing height in centimeters in Height (cm).
- Click “Calculate BMR” to estimate your daily resting calorie burn.
The Formula Used
BMR is calculated using the revised Mifflines-St Jeor Equation, widely recognized for high clinical accuracy:
* Where s = +5 for males and -161 for females
Frequently Asked Questions (FAQ)
What is Basal Metabolic Rate (BMR)?
BMR represents the number of calories your body burns while performing basic life-sustaining functions at total rest.
How does BMR differ from Total Daily Energy Expenditure (TDEE)?
BMR measures baseline metabolism without activity, whereas TDEE includes additional energy burned through daily movement and exercise.
Can I increase my BMR?
Building lean muscle mass, staying active, and maintaining healthy protein intake can elevate your metabolic rate over time.
Does BMR decrease as you age?
Yes, natural changes in metabolic speed and gradual muscle mass reduction cause BMR to decrease slowly with age.
Should I consume fewer calories than my BMR?
Eating below your BMR for extended periods is generally discouraged as it can lead to nutritional deficiencies and muscle loss.
