1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and physical activity. It's the number of calories needed to maintain your current weight.

2. How Does the Calculator Work?

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

\[ BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) + 5 \text{ (for men)} \] \[ BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) - 161 \text{ (for women)} \]

Then calculates TDEE:

\[ TDEE = BMR \times Activity Factor \]

Where Activity Factor ranges from 1.2 (sedentary) to 1.9 (extra active).

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management. To maintain weight, consume calories equal to TDEE. To lose weight, create a calorie deficit. To gain weight, create a calorie surplus.

4. Using the Calculator

Tips: Enter accurate weight in kg, height in cm, age in years, select gender and appropriate activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the TDEE calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas, but individual variations may occur.

Q2: Should I adjust my calorie intake based on goals?
A: Yes, for weight loss subtract 500 kcal/day, for weight gain add 500 kcal/day from your TDEE.

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

Q4: What if my activity level changes?
A: Update your activity factor in the calculator to reflect your current lifestyle.

Q5: Are there limitations to this calculation?
A: Individual metabolism, medical conditions, and body composition can affect actual calorie needs.
