1. What is TDEE?

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

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

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 multiplied by your daily activity level to estimate total calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for creating effective weight loss, maintenance, or muscle gain nutrition plans. It helps determine appropriate calorie intake for your goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level from the dropdown menu. For accurate results, use a recent BMR calculation from a reliable source or calculator.

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (±5kg/10lbs) or activity level changes.

Q2: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q3: How accurate are TDEE calculations?
A: They provide good estimates but individual variations exist. Adjust based on actual results over 2-3 weeks.

Q4: Should I eat at my TDEE for weight maintenance?
A: Yes, consuming calories equal to your TDEE should maintain your current weight.

Q5: How much should I adjust my intake for weight loss/gain?
A: For weight loss, subtract 300-500 calories from TDEE; for weight gain, add 300-500 calories.
