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 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)
• \( Activity Factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation calculates your total daily energy needs by multiplying your basal metabolic rate by an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Accurate TDEE estimation is crucial for weight management, athletic performance optimization, and creating effective nutrition plans for both weight loss and muscle gain goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level. All values must be valid (BMR > 0, activity factor between 1.2-1.9).

5. Frequently Asked Questions (FAQ)

Q1: What is BMR?
A: Basal Metabolic Rate (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 level?
A: Sedentary (office job, little exercise), Lightly Active (light exercise 1-3 days/week), Moderately Active (moderate exercise 3-5 days/week), Very Active (hard exercise 6-7 days/week), Extra Active (very hard exercise, physical job).

Q3: How accurate is TDEE calculation?
A: While this provides a good estimate, individual variations in metabolism and activity patterns can affect actual energy expenditure.

Q4: Should I use TDEE for weight loss?
A: Yes, consuming 500-1000 calories less than your TDEE typically results in 1-2 pounds of weight loss per week.

Q5: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 4-6 weeks for optimal accuracy.
