1. What is the James Smith TDEE Equation for Women?

The James Smith TDEE equation calculates Total Daily Energy Expenditure specifically for women, based on the Mifflin-St Jeor formula with James Smith's modifications. It estimates the total calories your body burns in a day, including basal metabolic rate and activity level.

2. How Does the Calculator Work?

The calculator uses the James Smith TDEE equation for women:

\[ TDEE = (655.1 + 9.563 \times weight + 1.850 \times height - 4.676 \times age) \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on activity level

Activity Factors:

Sedentary (little/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 is essential for weight management, whether your goal is weight loss, maintenance, or muscle gain. It helps determine appropriate calorie intake for your specific needs and activity level.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculation?
A: The James Smith formula provides a good estimate for most women, but individual variations in metabolism may affect accuracy.

Q2: Should I use this for weight loss?
A: Yes, subtract 300-500 calories from your TDEE for gradual weight loss of 0.5-1kg per week.

Q3: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (±5kg).

Q4: Does this work for pregnant or breastfeeding women?
A: No, this equation is not designed for pregnant or breastfeeding women who have different nutritional needs.

Q5: What if my activity level changes?
A: Update your activity factor selection to reflect your current exercise routine for accurate results.
