BMR Equation for Females:
| From: | To: |
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. This includes breathing, circulation, cell production, and nutrient processing. It represents the minimum energy required to keep your body functioning.
The calculator uses the BMR equation for females:
Where:
Explanation: This equation estimates the calories your body burns at complete rest based on your weight, height, and age.
Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It helps determine your daily caloric needs when combined with activity level.
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: Why is there a different equation for females?
A: Females typically have lower BMR than males due to differences in body composition, muscle mass, and hormonal factors.
Q2: What is a normal BMR range for females?
A: Normal BMR for adult females typically ranges from 1200-1500 kcal/day, but this varies based on age, weight, height, and body composition.
Q3: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (5+ kg) or annually as you age.
Q4: Can muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Individuals with higher muscle mass typically have higher BMR.
Q5: How can I use my BMR for weight management?
A: Multiply your BMR by your activity level factor to determine your total daily energy expenditure, then adjust your calorie intake based on your weight goals.
