1. What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions at rest. This calculator helps determine your daily calorie needs for weight loss without exercise.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years
• 1.2 — Sedentary activity multiplier (no exercise)
• 500 — Calorie deficit for weight loss

Explanation: The equation calculates your basal metabolic rate and then applies a sedentary activity factor with a 500-calorie deficit for safe weight loss.

3. Importance of BMR Calculation

Details: Understanding your BMR is essential for creating an effective weight loss plan. A 500-calorie daily deficit typically results in about 0.5kg weight loss per week.

4. Using the Calculator

Tips: Enter your current weight in kg, height in cm, and age in years. All values must be valid positive numbers for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates a 3500-calorie weekly deficit, which typically results in about 0.5kg of weight loss per week.

Q2: Is this calculator suitable for everyone?
A: This calculator is designed for adults. Consult a healthcare professional before starting any weight loss program, especially if you have medical conditions.

Q3: What if I want to maintain weight?
A: For weight maintenance, use BMR × 1.2 without subtracting 500 calories.

Q4: How accurate is this calculation?
A: This provides an estimate. Individual metabolism may vary based on muscle mass, genetics, and other factors.

Q5: Should I eat below my BMR?
A: It's generally not recommended to eat below your BMR as this can slow your metabolism and cause nutrient deficiencies.
