1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn per day when exercise is taken into account. It's calculated by multiplying your Basal Metabolic Rate (BMR) by an activity factor that represents your daily activity level.

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: The equation accounts for your base 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, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For accurate results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism can affect actual TDEE.

Q3: Should I recalculate my TDEE often?
A: Yes, especially if your weight, activity level, or body composition changes significantly.

Q4: Why are there different activity factors?
A: Different activity levels burn different amounts of calories. The factors account for this variation.

Q5: Can TDEE change throughout the week?
A: Yes, if your activity levels vary day to day. Consider calculating separate TDEEs for different days.
