1. What is the Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation is considered the most accurate for estimating Basal Metabolic Rate (BMR) in healthy individuals. This calculator adapts it to calculate a calorie goal for weight loss in women by accounting for activity level and creating a 500-calorie deficit.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

\[ Calorie\ Goal = (10 \times weight + 6.25 \times height - 5 \times age - 161) \times activity\_factor - 500 \]

Where:

\( weight \) — Body weight in kilograms
\( height \) — Height in centimeters
\( age \) — Age in years
\( activity\_factor \) — Multiplier based on activity level
\( -500 \) — Creates calorie deficit for weight loss

Explanation: The equation first calculates your BMR (calories burned at complete rest), then multiplies by activity level to estimate total daily energy expenditure (TDEE), then subtracts 500 calories to create a weight loss deficit.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is essential for healthy, sustainable weight loss. A 500-calorie daily deficit typically results in about 0.5kg (1lb) of weight loss per week.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates about 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.

Q2: Should I eat fewer calories for faster weight loss?
A: Women should generally not consume fewer than 1200 calories/day without medical supervision to avoid nutrient deficiencies.

Q3: How often should I recalculate my calorie needs?
A: Recalculate every 5-10kg of weight loss, as your calorie needs decrease with lower body weight.

Q4: Why does activity level matter?
A: More active individuals burn more calories and can therefore eat more while maintaining the same deficit.

Q5: Is this calculator only for women?
A: Yes, this uses the female-specific equation. Men should use a different calculator with the male equation.
