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 physical activity. It's the sum of all energy used for bodily functions and movement throughout 24 hours.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity \) — Activity multiplier based on lifestyle

Activity Multipliers:

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

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. It helps create personalized nutrition and fitness plans.

4. Using the Calculator

Tips: Enter your BMR in kcal and select your activity level based on your typical weekly exercise routine. For accurate results, use a reliable BMR calculator first.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculation?
A: It provides a good estimate, but individual variations in metabolism and activity can affect accuracy.

Q3: Should I eat my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or when your weight, activity level, or body composition changes significantly.

Q5: Can TDEE change throughout the week?
A: Yes, TDEE varies daily based on activity levels. This calculator gives an average estimate.
