Total Daily Energy Calculator For Women

TDEE Formula (Harris-Benedict for Women):

\[ TDEE = (447.593 + (9.247 \times weight) + (3.098 \times height) - (4.330 \times age)) \times activity \]

1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity. It's a crucial metric for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the Harris-Benedict equation for women:

\[ TDEE = (447.593 + (9.247 \times weight) + (3.098 \times height) - (4.330 \times age)) \times activity \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity \) — Activity level multiplier

Activity Level Multipliers:

Sedentary (little or no exercise): 1.2
Lightly active (light exercise 1-3 days/week): 1.375
Moderately active (moderate exercise 3-5 days/week): 1.55
Very active (hard exercise 6-7 days/week): 1.725
Extra active (very hard exercise & physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps in creating effective weight management plans. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. Maintaining weight requires matching calorie intake to TDEE.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Harris-Benedict equation?
A: While widely used, it provides an estimate. Individual variations in metabolism can affect actual energy expenditure.

Q2: Should I use my current weight or goal weight?
A: Use your current weight for accurate TDEE calculation. Adjust as your weight changes.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (2-3 kg) or your activity level changes substantially.

Q4: Can this calculator be used for men?
A: No, this specific calculator uses the equation for women. Men should use a different equation.

Q5: What if my activity level varies day to day?
A: Choose the multiplier that best represents your average weekly activity level for the most accurate estimate.
