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 your activity factor.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: Your BMR represents the calories your body needs at complete rest. The activity factor accounts for your daily movement and exercise.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you understand how many calories you need to maintain your current weight. This is the foundation for any weight loss, gain, or maintenance plan.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator or lab test) and select your activity level. The calculator will estimate your daily calorie needs for weight maintenance.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism and activity can affect actual TDEE.

Q2: What if I don't know my BMR?
A: Use a BMR calculator first, which typically requires age, gender, height, and weight.

Q3: How should I adjust calories for weight goals?
A: For weight loss, consume 250-500 kcal below TDEE. For gain, consume 250-500 kcal above.

Q4: Should I recalculate my TDEE often?
A: Yes, especially if your weight, activity level, or body composition changes significantly.

Q5: Why are there different activity factors?
A: Different activity levels burn different amounts of calories, so the multiplier adjusts for this.
