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 following equations:

Where:

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

Explanation: The 500 calorie deficit is a common recommendation for safe, sustainable weight loss (about 0.5kg per week).

3. Importance of BMR and TDEE Calculation

Details: Understanding your BMR and TDEE helps create effective weight loss plans by determining appropriate calorie intake while maintaining health.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select your activity level. For accurate results, measure weight and height precisely.

5. Frequently Asked Questions (FAQ)

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

Q2: What if I want to lose weight faster?
A: It's generally not recommended to consume fewer than 1200 calories/day without medical supervision.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Factors like muscle mass and medical conditions can affect actual energy needs.

Q4: Should I adjust my calories as I lose weight?
A: Yes, recalculate your BMR and TDEE every 5-10kg of weight loss as your energy needs will decrease.

Q5: Is this calculator only for women?
A: This specific equation is for women. Men should use a different BMR equation (10 × weight + 6.25 × height - 5 × age + 5).
