1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate (BMR) and activity. For women looking to lose weight fast, consuming 1000 kcal less than TDEE is often recommended.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( activity\ factor \) — Multiplier based on activity level (1.2-1.9)
• \( Intake \) — Recommended daily calorie intake for fast weight loss

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for effective weight management. A 1000 kcal deficit from TDEE typically leads to about 1 kg (2.2 lbs) of weight loss per week.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is a 1000 kcal deficit safe?
A: For most women, this is aggressive but generally safe. Consult a doctor if you have health concerns.

Q2: What if my recommended intake is very low?
A: Never consume fewer than 1200 kcal/day without medical supervision.

Q3: How often should I recalculate my TDEE?
A: Recalculate every 5-10 kg of weight loss or if your activity level changes significantly.

Q4: Why use the Mifflin-St Jeor equation?
A: It's currently the most accurate BMR estimation formula for healthy individuals.

Q5: What about macronutrients?
A: While calories matter most for weight loss, aim for adequate protein (1.6-2.2g/kg of body weight) to preserve muscle.
