1. What is TDEE Calculation?

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 formula:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( AF \) — Activity Factor (dimensionless)

Explanation: The equation multiplies your basal metabolic rate by an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management, diet planning, and achieving fitness goals. It helps determine appropriate calorie intake for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level. All values must be valid (BMR > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to perform basic life-sustaining functions at complete rest.

Q2: How do I determine my activity factor?
A: Choose based on your daily activity level: Sedentary (1.2), Lightly Active (1.375), Moderately Active (1.55), Very Active (1.725), or Extra Active (1.9).

Q3: How accurate is TDEE calculation?
A: While it provides a good estimate, individual variations in metabolism and activity patterns may affect accuracy.

Q4: Should I adjust my TDEE over time?
A: Yes, as your weight, body composition, and activity levels change, you should recalculate your TDEE periodically.

Q5: How should I use TDEE for weight management?
A: For weight loss, consume fewer calories than your TDEE; for weight gain, consume more; for maintenance, match your TDEE.
