1. What is TDEE?

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

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation with activity factor:

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 equation calculates your Basal Metabolic Rate (BMR) first, then multiplies it by an activity factor to estimate your total daily energy needs.

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. Maintaining weight requires matching calorie intake to your TDEE.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level based on your typical weekly exercise routine. Use accurate measurements for best results.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this calculator?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for healthy adults. Combined with appropriate activity factors, it provides a good TDEE estimate.

Q3: Should I adjust my TDEE over time?
A: Yes, as you lose/gain weight or change activity levels, your TDEE will change. Recalculate every 4-6 weeks or after significant lifestyle changes.

Q4: What if I'm pregnant or breastfeeding?
A: This calculator is not designed for pregnant or breastfeeding women. Consult with a healthcare professional for appropriate calorie recommendations.

Q5: How should I use my TDEE for weight loss?
A: For weight loss, create a calorie deficit of 500-1000 calories per day below your TDEE, aiming for 0.5-1kg weight loss per week.
