1. What is TDEE?

Total Daily Energy Expenditure (TDEE) 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 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, whether your goal is to lose, maintain, or gain weight. It helps determine appropriate calorie intake for your fitness objectives.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level from the dropdown menu. Make sure to use an accurate BMR value for the most precise TDEE calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and 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 when your weight changes significantly (±5kg/10lbs) or when your activity level changes substantially.

Q3: Is TDEE the same for everyone with the same weight?
A: No, TDEE varies based on body composition, age, gender, and individual metabolism in addition to weight and activity level.

Q4: Can I use TDEE for weight loss?
A: Yes, consuming 500-1000 calories less than your TDEE typically results in 0.5-1kg (1-2lbs) of weight loss per week.

Q5: How accurate is this calculation?
A: It provides a good estimate, but individual variations may occur. Use it as a starting point and adjust based on your results.
