1. What is the Weight Loss Calories Calculator?

This calculator estimates the daily calorie intake needed for weight loss in men, based on the Mifflin-St Jeor Equation with a 500-calorie deficit for approximately 0.5kg (1lb) of weight loss per week.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Calorie Calculation

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

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select your activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit typically results in about 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.

Q2: Should I eat exactly these calories?
A: This is an estimate. Monitor your progress and adjust as needed based on your body's response.

Q3: What if I'm not losing weight?
A: You may need to adjust your calorie intake, activity level, or check for medical conditions affecting metabolism.

Q4: Can women use this calculator?
A: This version is specifically for men. Women should use a different equation that accounts for female physiology.

Q5: How often should I recalculate?
A: Recalculate every 5-10kg of weight loss or if your activity level changes significantly.
