1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn per day when exercise is taken into account. It's calculated by first establishing your Basal Metabolic Rate (BMR), then multiplying that value by an activity multiplier.

2. How Does the Calculator Work?

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

Where:

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

Explanation: The equation calculates your BMR (calories burned at complete rest) then adjusts for your activity level to estimate total daily calorie needs.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management - consuming fewer calories than your TDEE leads to weight loss, while consuming more leads to weight gain.

4. Using the Calculator

Tips: For most accurate results, weigh yourself in the morning after using the bathroom. Be honest about your activity level - most people overestimate their activity.

5. Frequently Asked Questions (FAQ)

Q1: Why use this equation instead of others?
A: The Mifflin-St Jeor Equation is currently considered the most accurate for estimating BMR in healthy individuals.

Q2: What are typical TDEE values for women?
A: Most women have a TDEE between 1,600-2,500 kcal/day, depending on size, age, and activity level.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg) or your activity level changes substantially.

Q4: Are there limitations to this calculation?
A: The equation may be less accurate for very muscular individuals, the elderly, or those with high body fat percentages.

Q5: Should I eat exactly my TDEE to maintain weight?
A: TDEE is an estimate - you may need to adjust up or down based on actual weight changes over time.
