Lose Weight Calculator Calories for Women

Weight Loss Formula:

\[ \text{Daily Calories} = \text{TDEE} - \text{Deficit} \] \[ \text{TDEE} = \text{BMR} \times \text{Activity Factor} \] \[ \text{BMR (Women)} = 655 + (9.6 \times \text{weight in kg}) + (1.8 \times \text{height in cm}) - (4.7 \times \text{age in years}) \]

1. What is the Weight Loss Calculator?

This calculator estimates the daily calorie intake needed for women to lose weight based on their Basal Metabolic Rate (BMR), activity level, and desired calorie deficit.

2. How Does the Calculator Work?

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

\[ \text{BMR} = 655 + (9.6 \times \text{weight in kg}) + (1.8 \times \text{height in cm}) - (4.7 \times \text{age in years}) \] \[ \text{TDEE} = \text{BMR} \times \text{Activity Factor} \] \[ \text{Daily Calories} = \text{TDEE} - \text{Deficit} \]

Where:

\( \text{BMR} \) — Basal Metabolic Rate (calories burned at rest)
\( \text{TDEE} \) — Total Daily Energy Expenditure (calories burned including activity)
\( \text{Deficit} \) — Calorie reduction for weight loss (typically 500 kcal/day for 0.5kg/week loss)
\( \text{Activity Factor} \) — Multiplier based on physical activity level

3. Importance of Calorie Calculation

Details: Accurate calorie calculation helps create a sustainable weight loss plan by ensuring adequate nutrition while maintaining a calorie deficit for fat loss.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, select activity level, and desired calorie deficit. A 500 kcal/day deficit typically results in about 0.5kg weight loss per week.

5. Frequently Asked Questions (FAQ)

Q1: Why use the Mifflin-St Jeor equation?
A: It's currently considered the most accurate BMR equation for healthy individuals.

Q2: What's a safe calorie deficit?
A: 500-1000 kcal/day deficit is generally safe, resulting in 0.5-1kg weight loss per week.

Q3: Should I eat below my BMR?
A: Not recommended long-term as it may slow metabolism. Aim to stay above BMR unless supervised by a professional.

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

Q5: Why is this calculator for women only?
A: The BMR equation differs between genders due to differences in body composition. Men should use a different calculator.
