1. What Is The Calorie Calculator For Weight Loss?

The Calorie Calculator For Weight Loss estimates your daily calorie needs for weight loss based on your Total Daily Energy Expenditure (TDEE) minus a calorie deficit. It accounts for age, gender, weight, height, and activity level to provide personalized recommendations.

2. How Does The Calculator Work?

The calculator uses the Mifflin-St Jeor equation to estimate Basal Metabolic Rate (BMR), then calculates TDEE based on activity level:

\[ \text{BMR} = 10 \times \text{weight} + 6.25 \times \text{height} - 5 \times \text{age} + (5 \text{ if male, } -161 \text{ if female}) \] \[ \text{TDEE} = \text{BMR} \times \text{Activity Factor} \] \[ \text{Daily Calorie Intake} = \text{TDEE} - \text{Deficit} \]

Where:

\( \text{weight} \) — Weight in kilograms
\( \text{height} \) — Height in centimeters
\( \text{age} \) — Age in years
\( \text{Activity Factor} \) — Multiplier based on activity level
\( \text{Deficit} \) — Calorie deficit for weight loss (typically 500 kcal/day)

3. Importance Of Calorie Calculation

Details: Accurate calorie calculation is essential for effective weight loss. Consuming fewer calories than you burn creates a deficit leading to weight loss, while maintaining the right balance ensures healthy and sustainable progress.

4. Using The Calculator

Tips: Enter your age in years, select gender, input weight in kg and height in cm, choose your activity level, and specify your desired calorie deficit (typically 500 kcal/day for gradual weight loss).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate based on population averages, but individual metabolism can vary by ±10-15%.

Q2: What's a safe calorie deficit?
A: 500 kcal/day deficit is generally safe, leading to about 0.5kg (1lb) weight loss per week. Avoid deficits >1000 kcal/day without medical supervision.

Q3: Should I adjust my calories as I lose weight?
A: Yes, recalculate every 5-10kg lost as your BMR decreases with weight loss.

Q4: Why does age affect calorie needs?
A: Metabolism naturally slows with age due to decreased muscle mass and hormonal changes.

Q5: How often should I recalculate?
A: Recalculate every 3-6 months or after significant weight changes (±5kg) or activity level changes.
