1. What Is Total Daily Energy Expenditure?

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 and digestion.

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
• Extremely 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 and select your activity level. First calculate your BMR using a BMR calculator, then use this calculator to determine your total daily calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: What is 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 are TDEE calculations?
A: They provide good estimates but individual variations exist. Monitor your weight and adjust based on results.

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 when your weight changes significantly or your activity level changes substantially.

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