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 (BMR), physical activity, and the thermic effect of food. It's the most accurate way to determine your daily calorie needs.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity \) — Activity multiplier based on lifestyle
• \( Adjustments \) — Additional calorie adjustments for specific needs

Explanation: The equation accounts for your base metabolic rate multiplied by your activity level, with optional adjustments for specific dietary requirements or goals.

3. Importance of TDEE Calculation

Details: Accurate TDEE calculation is crucial for weight management, whether your goal is weight loss, maintenance, or muscle gain. It provides the scientific basis for creating effective nutrition plans.

4. Using the Calculator

Tips: Enter your BMR in kcal, select your activity level, and add any necessary adjustments. All values must be valid (BMR > 0, activity level between 1.2-1.9).

5. Frequently Asked Questions (FAQ)

Q1: Why is TDEE more accurate than simple calorie calculators?
A: TDEE accounts for individual metabolic rate, activity level, and specific adjustments, providing personalized results rather than generic estimates.

Q2: How do I determine my BMR?
A: BMR can be measured through metabolic testing or estimated using formulas like Mifflin-St Jeor or Harris-Benedict equations.

Q3: What activity level should I choose?
A: Select the level that best matches your daily physical activity, including both exercise and non-exercise activities.

Q4: When should I use adjustments?
A: Use adjustments for specific goals like weight loss (negative adjustment) or muscle gain (positive adjustment), or to account for special metabolic conditions.

Q5: 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.
