1. What Is This Calorie Calculator?

This calculator estimates the daily calorie intake needed for weight loss in women based on the Mifflin-St Jeor equation, adjusted for activity level with a 500 kcal deficit for gradual weight loss.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

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

Explanation: The formula calculates your Basal Metabolic Rate (BMR), adjusts for activity level, then subtracts 500 kcal to create a deficit for weight loss (approximately 0.5kg per week).

3. Importance Of Calorie Calculation

Details: Accurate calorie estimation is crucial for sustainable weight loss, ensuring you create an appropriate deficit without compromising nutrition or energy levels.

4. Using The Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500 kcal daily deficit typically results in about 0.5kg weight loss per week, considered a safe and sustainable rate.

Q2: What if I'm not losing weight at this calorie level?
A: Metabolic adaptations may occur. Reassess your activity level, measurements, and consider consulting a nutritionist.

Q3: Should I eat back exercise calories?
A: The activity factor already accounts for regular exercise. Only additional, unusual exercise might warrant small adjustments.

Q4: How often should I recalculate?
A: Recalculate every 5-10kg of weight loss or if your activity level changes significantly.

Q5: Is this suitable for everyone?
A: This is specifically for adult women. Men, adolescents, pregnant/nursing women, and those with medical conditions should use specialized calculators.
