1. What is the Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation is considered the most accurate for estimating basal metabolic rate (BMR) and total daily energy expenditure (TDEE). This calculator provides calorie recommendations for weight loss (500 kcal deficit).

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 for physical activity level
• 500 — Calorie deficit for weight loss

Explanation: The equation calculates your basal metabolic rate (BMR), then adjusts for activity level, and finally subtracts 500 calories for weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for effective weight loss while maintaining health and muscle mass. The 500 kcal deficit typically leads to about 0.5 kg (1 lb) of weight loss per week.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level. For best results, use morning measurements before eating.

5. Frequently Asked Questions (FAQ)

Q1: Why use Mifflin-St Jeor instead of Harris-Benedict?
A: Mifflin-St Jeor is more accurate for modern populations, especially for obese individuals.

Q2: How accurate is this calculation?
A: It provides a good estimate (±10%) for most people, but individual variations exist.

Q3: Should I eat exactly these calories?
A: Use this as a starting point and adjust based on your weight loss progress.

Q4: What if I'm not losing weight?
A: You may need to adjust your calorie intake or activity level. Consider consulting a dietitian.

Q5: Can men use this calculator?
A: No, this is specifically for women. Men should use the male version of the equation.
