1. What is BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest. TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day including physical activity.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equations:

Where:

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

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

3. Importance of Calorie Calculation

Details: Knowing your TDEE helps with weight management - consuming fewer calories than your TDEE leads to weight loss, while consuming more leads to weight gain.

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: Is this calculator only for men?
A: Yes, this specific calculator uses the equation for men. Women should use a different equation.

Q2: How accurate is the BMR calculation?
A: It's an estimate - individual variations in metabolism can cause actual BMR to differ by ±10%.

Q3: What's the best activity factor to choose?
A: Be honest about your activity level. Most people overestimate their activity.

Q4: Should I eat exactly my TDEE to maintain weight?
A: TDEE is an estimate. Monitor your weight and adjust calories as needed.

Q5: How often should I recalculate?
A: Recalculate after significant weight changes (±5kg) or activity level changes.
