1. What is the Daily Calorie Intake Calculator?

The Daily Calorie Intake Calculator estimates the number of calories needed for weight loss based on your Basal Metabolic Rate (BMR) and Physical Activity Level (PAL). It follows the Australian guidelines for weight loss calorie calculation.

2. How Does the Calculator Work?

The calculator uses the calorie equation:

\[ Daily = BMR \times PAL - 500 \]

Where:

\( BMR \) — Basal Metabolic Rate (kcal)
\( PAL \) — Physical Activity Level (1.4-1.9)
\( 500 \) — Calorie deficit for weight loss

Explanation: The equation calculates your total daily energy expenditure and subtracts 500 calories to create a deficit for gradual weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is crucial for effective weight management, ensuring you create an appropriate calorie deficit without compromising nutrition or health.

4. Using the Calculator

Tips: Enter your BMR in kcal, select your appropriate PAL level (1.4-1.9). All values must be valid (BMR > 0, PAL between 1.4-1.9).

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how do I calculate it?
A: BMR (Basal Metabolic Rate) is the number of calories your body needs at rest. You can use various formulas like Mifflin-St Jeor or Harris-Benedict to calculate it.

Q2: What PAL level should I choose?
A: Choose based on your activity level: 1.4 (sedentary), 1.5 (light activity), 1.6 (moderate activity), 1.7 (very active), 1.8 (extremely active), or 1.9 (athlete level).

Q3: Why subtract 500 calories?
A: A 500-calorie daily deficit typically results in about 0.5kg weight loss per week, which is considered safe and sustainable.

Q4: Are there limitations to this calculation?
A: Individual variations in metabolism, medical conditions, and other factors may affect actual calorie needs. Consult a healthcare professional for personalized advice.

Q5: Should I use this calculation long-term?
A: This is designed for weight loss. Once you reach your goal weight, you should recalculate your maintenance calories (BMR × PAL without the 500 deficit).
