1. What is BMR and Calorie Calculation?

BMR (Basal Metabolic Rate) represents the number of calories your body needs to perform basic life-sustaining functions at rest. Total daily calorie needs are calculated by multiplying BMR by an activity factor that accounts for your daily physical activity level.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years
• \( activity factor \) — Multiplier based on physical activity level

Explanation: The formula calculates the basal metabolic rate and then adjusts it based on your activity level to determine total daily calorie needs.

3. Importance of BMR and Calorie Calculation

Details: Understanding your BMR and daily calorie needs is essential for weight management, creating effective diet plans, and maintaining overall health and fitness goals.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities and is calculated as BMR multiplied by activity factor.

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

Q3: Should I use this for weight loss?
A: Yes, knowing your calorie needs helps create a calorie deficit for weight loss or surplus for weight gain.

Q4: How often should I recalculate my BMR?
A: Recalculate when your weight changes significantly or every few months to account for metabolic changes.

Q5: Are there other factors that affect BMR?
A: Yes, factors like muscle mass, genetics, hormones, and environmental temperature can influence BMR.
