1. What Is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate (BMR) and activity. It's crucial for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

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

Explanation: Your BMR accounts for 60-75% of TDEE, while physical activity accounts for the remainder. The activity factor adjusts for different levels of daily movement and exercise.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps determine appropriate calorie intake for weight loss, maintenance, or gain. It's fundamental for creating effective nutrition plans.

4. Using the Calculator

Tips: First calculate your BMR using a BMR calculator, then select your activity level based on your typical weekly exercise routine.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: It provides a good estimate but individual variations exist. Track your results and adjust as needed.

Q2: Should I use sedentary or actual activity level?
A: Use your actual activity level for maintenance calories, sedentary for weight loss calculations.

Q3: How often should I recalculate TDEE?
A: Recalculate after significant weight changes (±10 lbs) or activity level changes.

Q4: What's the difference between TDEE and BMR?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q5: Can TDEE change day to day?
A: Yes, based on activity levels. The calculator provides an average estimate.
