1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. It's essential for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

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

Explanation: The equation first calculates Basal Metabolic Rate (BMR) using the Mifflin-St Jeor formula, then multiplies by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps in creating effective weight management plans. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

Tips: Enter accurate weight in kg, height in cm, age in years, and select the appropriate activity factor that matches your daily routine.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this TDEE calculation?
A: While the Mifflin-St Jeor formula is one of the most accurate BMR formulas, TDEE estimates can vary based on individual metabolism and accurate activity level selection.

Q3: Should I use this calculator for weight loss?
A: Yes, subtract 300-500 calories from your TDEE for gradual weight loss of 0.5-1kg per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg) or your activity level changes substantially.

Q5: Are there limitations to this calculation?
A: This formula may be less accurate for extremely muscular individuals, those with very high body fat percentages, or people with certain medical conditions.
