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 physical activity. It's crucial 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 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. For maintenance, match your intake to your TDEE.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level based on your weekly exercise routine and daily activity patterns.

5. Frequently Asked Questions (FAQ)

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

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

Q3: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 3-6 months for maintenance.

Q4: Can TDEE change over time?
A: Yes, TDEE decreases with age, weight loss, and reduced activity levels due to changes in metabolism and body composition.

Q5: Should I eat exactly at my TDEE for maintenance?
A: Use it as a starting point and adjust based on your actual weight changes and energy levels over 2-4 weeks.
