TDEE Equation:

The TDEE (Total Daily Energy Expenditure) Calculator for Women James estimates the total number of calories your body burns in a day, based on the Harris-Benedict formula. It accounts for your basal metabolic rate (BMR) and activity level to provide an accurate estimate of your daily energy needs.
The calculator uses the Harris-Benedict equation for women:
Where:
Explanation: The equation first calculates your Basal Metabolic Rate (BMR) - the calories your body needs at complete rest, then multiplies it by your activity factor to determine your total daily energy expenditure.
Details: Knowing your TDEE is essential for weight management, whether you want to lose, maintain, or gain weight. It helps you set appropriate calorie targets for your goals and ensures you're providing your body with adequate energy for optimal function.
Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. Be honest about your activity level for the most accurate results. All values must be valid (weight > 0, height > 0, age between 1-120).
Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the calories your body burns at complete rest, while TDEE (Total Daily Energy Expenditure) includes all calories burned through daily activities and exercise.
Q2: How accurate is the Harris-Benedict formula?
A: While not perfect, it provides a good estimate for most people. Individual variations in metabolism can cause actual TDEE to differ by ±10-15%.
Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.
Q4: Can this calculator be used for men?
A: No, this specific calculator uses the Harris-Benedict formula for women. Men should use a different equation with different coefficients.
Q5: What if I'm pregnant or breastfeeding?
A: This calculator is not designed for pregnant or breastfeeding women, as their energy needs are significantly different. Consult with a healthcare provider for appropriate calorie recommendations.
