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 and physical activity. It's essential for weight management and nutritional planning.

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 Levels:

• Sedentary (1.2): Little to 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
• Extremely Active (1.9): Very hard exercise, physical job

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized nutrition plans and fitness goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your weekly exercise routine. Ensure BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using formulas like Harris-Benedict or Mifflin-St Jeor, which consider age, weight, height, and gender.

Q2: Is TDEE the same for everyone with the same weight?
A: No, TDEE varies based on age, gender, muscle mass, genetics, and activity level, not just weight.

Q3: How accurate is the activity factor?
A: Activity factors are estimates. Individual variations in metabolism and exercise intensity can affect actual energy expenditure.

Q4: Should I adjust my TDEE over time?
A: Yes, as you lose/gain weight or change activity levels, recalculate your TDEE for accurate calorie targets.

Q5: Can TDEE be used for athletic training?
A: Yes, athletes often use TDEE to ensure adequate calorie intake for performance and recovery.
