1. What is the Female Calorie Equation?

The female calorie equation estimates daily calorie needs based on weight, height, age, and activity level. It's derived from the Mifflin-St Jeor Equation, which is considered one of the most accurate formulas for calculating basal metabolic rate (BMR).

2. How Does the Calculator Work?

The calculator uses the female calorie equation:

Where:

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

Explanation: The equation first calculates basal metabolic rate (calories needed at complete rest), then multiplies by an activity factor to estimate total daily energy expenditure.

3. Importance of Calorie Calculation

Details: Knowing your daily calorie needs helps with weight management, whether your goal is maintenance, loss, or gain. It provides a scientific basis for meal planning.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select your activity level. For accurate results, use recent measurements and be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate for most women, but individual variations in metabolism can affect actual calorie needs.

Q2: Should I eat fewer calories to lose weight?
A: A moderate deficit of 300-500 calories/day is recommended for sustainable weight loss (0.5-1 kg/week).

Q3: Do I need to adjust my calories as I age?
A: Yes, calorie needs typically decrease with age due to reduced muscle mass and metabolic changes.

Q4: What if I'm pregnant or breastfeeding?
A: This calculator isn't designed for pregnancy/lactation - consult a healthcare provider for nutritional guidance.

Q5: How often should I recalculate my needs?
A: Recalculate after significant weight changes (>5 kg) or changes in activity level.
