1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. This calculator provides a calorie recommendation for men who want to lose weight at a safe rate of about 0.5kg per week.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for men:

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 estimates your resting calorie needs, then adjusts for activity level and creates a deficit for weight loss.

3. Importance of BMR Calculation

Details: Knowing your BMR helps create effective weight loss plans. A 500-calorie daily deficit typically leads to about 0.5kg weight loss per week.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates about 0.5kg weight loss per week, which is a safe, sustainable rate for beginners.

Q2: Is this calculator only for men?
A: Yes, this uses the male equation. Women should use a different equation as their BMR calculation differs.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Factors like muscle mass and medical conditions can affect actual BMR.

Q4: Should I eat fewer than the recommended calories?
A: Not without medical supervision. Very low calorie diets can be harmful and counterproductive for weight loss.

Q5: When should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or every few months as you lose weight.
