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 essential for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for women:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years
• \( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation calculates your basal metabolic rate (BMR) and then multiplies it by an activity factor to estimate your total daily energy needs.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you determine appropriate calorie intake for weight loss, maintenance, or muscle gain. It provides a scientific basis for creating effective diet plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. Use accurate measurements for the most precise results.

5. Frequently Asked Questions (FAQ)

Q1: Why use the Mifflin-St Jeor Equation?
A: The Mifflin-St Jeor Equation is considered one of the most accurate BMR formulas, especially for the general population.

Q2: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or whenever your weight changes significantly, as your BMR changes with body composition.

Q3: What if my activity level changes?
A: Update your activity factor selection to reflect any significant changes in your exercise routine or daily activity patterns.

Q4: Are there limitations to this calculation?
A: Individual variations in metabolism, body composition, and other factors may cause actual energy expenditure to differ from calculated values.

Q5: Should I eat exactly at my TDEE for maintenance?
A: The calculated TDEE is an estimate. Monitor your weight over time and adjust your calorie intake based on your actual results and goals.
