1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn each day, including both basal metabolic rate (BMR) and calories burned through physical activity.

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

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. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more calories than your TDEE.

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 calculation.

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from TDEE?
A: BMR represents calories burned 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 (±10 lbs/4.5 kg) or your activity level changes substantially.

Q3: Can TDEE vary day to day?
A: Yes, TDEE can vary based on daily activity levels, but the calculator provides an average estimate.

Q4: Is this calculation accurate for athletes?
A: While generally accurate, elite athletes with extreme training regimens may need more specialized calculations.

Q5: How should I use TDEE for weight loss?
A: For weight loss, create a calorie deficit of 300-500 calories below your TDEE for steady, sustainable weight loss.
