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 health monitoring.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( \text{activity multiplier} \) — Sedentary: 1.2, Light: 1.375, Moderate: 1.55, Very Active: 1.725, Extra Active: 1.9

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

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management, nutrition 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 activity level. All values must be valid (BMR > 0). For accurate results, use a reliable BMR calculator first.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how is it different from TDEE?
A: BMR is the calories your body burns at rest for basic functions, while TDEE includes all calories burned including physical activity.

Q2: How accurate are the activity multipliers?
A: The multipliers provide estimates based on general activity levels. Individual variations may occur based on specific exercise routines and metabolism.

Q3: Should I use TDEE for weight loss?
A: Yes, consuming 500-1000 calories less than your TDEE per day typically results in safe weight loss of 1-2 pounds per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 4-6 weeks for ongoing weight management.

Q5: Can TDEE change over time?
A: Yes, TDEE can change with age, weight fluctuations, muscle mass changes, and alterations in activity levels.
