1. What is the Calories for Weight Loss Equation?

The calories equation estimates daily calorie needs for weight loss based on weight, height, age, and activity level. It provides a 500-calorie deficit from maintenance calories, which typically results in about 0.5kg weight loss per week.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation calculates basal metabolic rate adjusted for activity level, then subtracts 500 calories to create a weight loss deficit.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for sustainable weight loss while maintaining adequate nutrition and energy levels.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select your activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: 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.

Q2: What if I want faster weight loss?
A: Consult a healthcare professional before creating larger deficits. Very low calorie diets require medical supervision.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual metabolism varies. Adjust based on your actual weight loss results.

Q4: Should I eat fewer calories than this?
A: Women should generally not consume fewer than 1200 calories/day without medical supervision to ensure adequate nutrition.

Q5: How often should I recalculate?
A: Recalculate every 5-10kg of weight loss, as calorie needs decrease with lower body weight.
