Weight Loss Calculator For Women

Weight Loss Formula:

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

1. What is the Weight Loss Calculator For Women?

This calculator estimates the daily calorie intake needed for weight loss in women based on the Mifflin-St Jeor equation for BMR, adjusted for activity level and a calorie deficit.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ \text{Daily Calorie Intake} = \text{TDEE} - \text{Deficit} \] \[ \text{TDEE} = \text{BMR} \times \text{Activity Factor} \] \[ \text{BMR (Women)} = 655 + (9.6 \times \text{weight}) + (1.8 \times \text{height}) - (4.7 \times \text{age}) \]

Where:

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

Explanation: The equation calculates how many calories your body needs at rest (BMR), then adjusts for activity level (TDEE), and finally subtracts your desired deficit for weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation helps create a sustainable weight loss plan. A deficit of 500 kcal/day typically leads to about 0.5kg (1lb) of weight loss per week.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select your activity level, and choose a calorie deficit (500 kcal/day is a common starting point).

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculator specific to women?
A: Women typically have different body compositions and metabolic rates than men, so gender-specific formulas provide more accurate results.

Q2: What's a safe calorie deficit?
A: 300-500 kcal/day is generally safe. Extreme deficits (<1200 kcal/day) should be medically supervised.

Q3: How accurate is the BMR calculation?
A: The Mifflin-St Jeor equation is about 80% accurate for most people. Individual variations exist.

Q4: Should I adjust my calories as I lose weight?
A: Yes, recalculate every 5-10 kg lost, as your BMR decreases with weight loss.

Q5: What if my weight loss stalls?
A: Reassess your activity level and calorie intake, as both may need adjustment over time.
