1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories you burn in a day, including your basal metabolic rate (BMR) and calories burned through activity.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories your body needs at complete rest)
• \( Activity Factor \) — Multiplier based on your activity level (1.2 to 1.9)

Explanation: The equation accounts for your basic metabolic needs plus additional calories burned through physical activity.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more.

4. Using the Calculator

Tips: Enter your BMR (calculated separately) and select your activity level based on your typical weekly exercise routine.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using equations like Mifflin-St Jeor or Harris-Benedict, which consider age, gender, weight and height.

Q2: What if my activity level changes day to day?
A: Choose the activity factor that best represents your average weekly activity.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations in metabolism can affect actual calorie burn.

Q4: Should I adjust my calorie intake based on exercise?
A: Yes, more active days may require more calories, especially if you're trying to maintain weight.

Q5: Does muscle mass affect TDEE?
A: Yes, muscle tissue burns more calories at rest than fat tissue, so those with more muscle mass typically have higher TDEE.
