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 (BMR) and calories burned through physical activity.

2. How Is TDEE Calculated?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( \text{activity factor} \) — Multiplier based on activity level (unitless)

Activity Factors:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise 1-3 days/week): 1.375
• Moderately active (moderate exercise 3-5 days/week): 1.55
• Very active (hard exercise 6-7 days/week): 1.725
• Extra active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether your goal is to lose, maintain, or gain weight. It helps determine appropriate daily calorie intake.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine. For accurate results, use a recent BMR measurement or calculation.

5. Frequently Asked Questions (FAQ)

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

Q2: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg/10lbs) or your activity level changes substantially.

Q3: Are activity factors accurate for everyone?
A: They provide estimates. Individual variations exist based on metabolism, body composition, and exercise intensity.

Q4: Can TDEE change throughout the week?
A: Yes, your TDEE varies daily based on activity levels. The calculator provides an average estimate.

Q5: Should I eat exactly at my TDEE to maintain weight?
A: TDEE provides an estimate. Monitor your weight over time and adjust calorie intake as needed for your goals.
