1. What is the Weight Loss Calculator?

The Weight Loss Calculator for Australian Women estimates daily calorie needs for safe weight loss (approximately 0.5kg per week) based on your Basal Metabolic Rate (BMR) and activity level.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level
• 500 — Calorie deficit for ~0.5kg weight loss per week

Explanation: The equation accounts for your body's energy needs at rest (BMR) adjusted for activity level, then creates a moderate deficit for sustainable weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation helps ensure safe, sustainable weight loss while maintaining energy levels and nutritional adequacy.

4. Using the Calculator

Tips: Enter your BMR in kcal/day (use a BMR calculator if unknown) and select your activity level. For best results, combine with balanced nutrition and regular exercise.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500 kcal daily deficit typically results in ~0.5kg weight loss per week, considered safe and sustainable.

Q2: What if I want faster weight loss?
A: We don't recommend deficits greater than 500-750 kcal/day without medical supervision.

Q3: How accurate is this calculator?
A: It provides estimates. Individual results may vary based on metabolism, body composition, and other factors.

Q4: Should I eat fewer calories than calculated?
A: Not without professional advice. Very low calorie diets can be harmful and counterproductive.

Q5: How often should I recalculate?
A: Reassess every 4-6 weeks or with significant weight or activity level changes.
