1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest. It represents the minimum energy required to keep your body functioning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation:

Where:

• Weight — in kilograms (kg)
• Height — in centimeters (cm)
• Age — in years
• Activity Multiplier — Based on daily activity level

3. Importance of BMR Calculation for Weight Loss

Details: Understanding your BMR and TDEE is crucial for effective weight management. By creating a calorie deficit of 500 calories per day, you can achieve a safe and sustainable weight loss of approximately 0.5 kg per week.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select your gender and activity level. For accurate results, use your current measurements and be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories for weight loss?
A: A deficit of 500 calories per day typically results in losing about 0.5 kg per week, which is considered a safe and sustainable rate of weight loss.

Q2: How accurate is the BMR calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for the general population, but individual variations may occur.

Q3: Should I eat below my BMR to lose weight?
A: No, you should never eat below your BMR as this can slow down your metabolism and cause muscle loss. Always create a deficit from your TDEE, not your BMR.

Q4: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (more than 5 kg) or every 3-6 months to account for metabolic changes during weight loss.

Q5: Can this calculator be used for weight gain?
A: Yes, simply add 300-500 calories to your TDEE instead of subtracting for healthy weight gain.
