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 level. 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

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 helps with weight loss (eat below TDEE), maintenance (eat at TDEE), or weight gain (eat above TDEE). It's fundamental for personalized nutrition planning.

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: How do I calculate my BMR?
A: Use a BMR calculator (like Mifflin-St Jeor equation) that considers your age, gender, weight, and height.

Q2: What if my activity varies day to day?
A: Choose the level that best represents your average weekly activity, or calculate separate TDEEs for different days.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg) or your activity level changes substantially.

Q4: Are there limitations to this calculation?
A: It's an estimate. Individual variations in metabolism, NEAT (non-exercise activity thermogenesis), and other factors can affect actual energy expenditure.

Q5: Should I adjust my TDEE for weight loss?
A: For weight loss, typically subtract 300-500 kcal from your TDEE, but consult a nutritionist for personalized advice.
