BMR Equation:
| From: | To: |
The BMR (Basal Metabolic Rate) equation estimates the number of calories your body needs to perform basic life-sustaining functions at rest. This equation uses weight in pounds, height in inches, and age in years to calculate daily calorie requirements.
The calculator uses the BMR equation:
Where:
Explanation: The equation calculates the basal metabolic rate based on body size and age, representing the calories needed for basic bodily functions at complete rest.
Details: Knowing your BMR is essential for weight management, creating effective diet plans, and understanding your body's energy requirements. It serves as the foundation for calculating total daily energy expenditure.
Tips: Enter your weight in pounds, height in inches, and age in years. All values must be valid positive numbers (weight > 0, height > 0, age between 1-120).
Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to maintain basic physiological functions while at complete rest, including breathing, circulation, and cell production.
Q2: How accurate is this BMR calculation?
A: This equation provides a good estimate for most people, but individual variations in metabolism, body composition, and other factors can affect actual BMR.
Q3: Should I use BMR or TDEE for diet planning?
A: BMR represents your baseline calorie needs. For diet planning, you should calculate your Total Daily Energy Expenditure (TDEE) by multiplying BMR by an activity factor.
Q4: How often does BMR change?
A: BMR changes with age, weight fluctuations, muscle mass changes, and overall health status. It's recommended to recalculate periodically.
Q5: Can I increase my BMR?
A: Yes, building muscle mass through strength training, maintaining proper hydration, and ensuring adequate protein intake can help increase your metabolic rate.
