1. What is the Weight Calorie Calculator?

The Weight Calorie Calculator for Women estimates the daily calorie intake needed for healthy weight loss (about 0.5 kg per week) based on your basal metabolic rate (BMR) and activity level.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calculated using Mifflin-St Jeor Equation)
• \( activity\_factor \) — Multiplier based on your activity level
• 500 — Calorie deficit for gradual weight loss

BMR Calculation (Women): \[ BMR = (10 \times weight\:in\:kg) + (6.25 \times height\:in\:cm) - (5 \times age) - 161 \]

3. Importance of Calorie Calculation

Details: Calculating appropriate calorie intake is essential for safe and sustainable weight loss. A 500-calorie daily deficit typically results in about 0.5 kg weight loss per week.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, age in years, and select your typical activity level. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculator only for women?
A: Yes, this specific calculator uses equations optimized for women's physiology. Men should use a different BMR equation.

Q2: Why subtract 500 calories?
A: A 500-calorie daily deficit creates about a 3500-calorie weekly deficit, which equals roughly 0.5 kg of fat loss.

Q3: Can I lose weight faster with a larger deficit?
A: While possible, deficits greater than 500-750 calories/day may lead to muscle loss, nutrient deficiencies, and metabolic slowdown.

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

Q5: Should I eat back exercise calories?
A: The activity factor already accounts for regular exercise. Only eat back calories if you do extra, unplanned exercise.
