BMR Calculator
Understanding your Basal Metabolic Rate (BMR) is key to managing weight and energy levels. BMR represents the number of calories your body needs to maintain basic functions like breathing, circulation, and cell production. This calculator simplifies determining your BMR.
Formula
The formula to calculate BMR is:
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + constant
The constant is +5 for men and −161 for women.
How to Use
- Enter your weight in kilograms.
- Enter your height in centimeters.
- Input your age in years.
- Select your gender (male or female).
- Click “Calculate” to see your BMR result.
Example
For a male weighing 70 kg, 175 cm tall, and aged 25:
BMR = (10 × 70) + (6.25 × 175) − (5 × 25) + 5
BMR = 700 + 1093.75 − 125 + 5 = 1673.75 kcal/day
FAQs
- What is BMR?
BMR stands for Basal Metabolic Rate, the calories required for basic bodily functions at rest. - Why is BMR important?
BMR helps determine daily calorie needs for weight loss, gain, or maintenance. - Does gender affect BMR?
Yes, men and women have different constants in the formula. - Can I use this calculator for children?
It’s designed for adults. Consult a pediatrician for children’s calorie needs. - How accurate is the BMR formula?
It provides an estimate but may vary depending on body composition. - What factors affect BMR?
Weight, height, age, and gender are key factors. - Does muscle mass affect BMR?
Yes, more muscle mass increases BMR as muscles require more energy. - Is BMR the same as TDEE?
No, TDEE (Total Daily Energy Expenditure) includes activity levels, while BMR does not. - How can I increase my BMR?
Strength training and increasing muscle mass can boost BMR. - Can BMR decrease over time?
Yes, BMR decreases with age and loss of muscle mass. - What should I do with my BMR result?
Use it to plan calorie intake based on your health goals. - Is the BMR calculator free to use?
Yes, it’s completely free. - Do I need to recalculate BMR if my weight changes?
Yes, any significant weight change will affect BMR. - Can medical conditions influence BMR?
Yes, conditions like thyroid issues can impact BMR. - What’s the difference between BMR and RMR?
RMR (Resting Metabolic Rate) is slightly different, often including additional factors like digestion.
Conclusion
Calculating your BMR is a foundational step in understanding your body’s energy needs. By using this simple yet effective tool, you can tailor your nutrition and fitness goals for a healthier lifestyle.
