1. What is the BMR Equation?

The BMR (Basal Metabolic Rate) equation estimates the number of calories your body needs to perform basic life-sustaining functions at rest. It's a fundamental calculation for weight loss planning as it determines your baseline calorie requirements.

2. How Does the Calculator Work?

The calculator uses the BMR equation:

Where:

• \( Weight \) — Body weight in kilograms (kg)
• \( Height \) — Height in centimeters (cm)
• \( Age \) — Age in years
• 5 — Constant added for males
• -161 — Constant subtracted for females

Explanation: The equation calculates the minimum energy required to maintain vital body functions while at complete rest.

3. Importance of BMR Calculation for Weight Loss

Details: Knowing your BMR is essential for effective weight loss planning. It helps determine your daily calorie needs and creates appropriate calorie deficits for sustainable weight loss without compromising basic metabolic functions.

4. Using the Calculator

Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How accurate is this BMR calculation?
A: This equation provides a good estimate for most people, but individual variations in metabolism may affect accuracy.

Q3: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or every few months during weight loss.

Q4: Can BMR change over time?
A: Yes, BMR decreases with age and can be affected by muscle mass, hormonal changes, and weight loss itself.

Q5: How should I use BMR for weight loss?
A: Create a calorie deficit of 500-1000 calories below your TDEE (which is higher than BMR) for safe weight loss of 0.5-1 kg per week.
