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 a crucial metric for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation accounts for your base metabolic rate multiplied by an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for creating effective weight loss, maintenance, or muscle gain plans. It helps determine appropriate calorie intake for your goals.

4. Using the Calculator

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

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 complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate are activity factors?
A: Activity factors provide estimates. Individual variations in metabolism and activity intensity can affect accuracy.

Q3: Should I use sedentary or active factor if I exercise occasionally?
A: Choose the factor that best represents your average weekly activity level, not just your workout days.

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

Q5: Can TDEE change throughout the week?
A: Yes, TDEE varies daily based on activity. The calculator provides an average estimate for consistent planning.
