1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, accounting for your basal metabolic rate (BMR), physical activity, and digestion of food.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at complete rest)
• \( activity\_factor \) — Multiplier based on daily activity level
• \( exercise\_calories \) — Additional calories burned through exercise

Explanation: The equation accounts for your base metabolism plus additional energy expenditure from daily activities and exercise.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more.

4. Using the Calculator

Tips: For best results, calculate your BMR first using a BMR calculator. Choose the activity factor that best matches your lifestyle. Include additional exercise calories if you want to account for specific workouts.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculation?
A: It provides a good estimate but individual variations exist. For more precision, track your actual calorie intake and weight changes over time.

Q2: Should I eat my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight, assuming accurate calculation.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes substantially.

Q4: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q5: Why include exercise calories separately?
A: Some people prefer to account for exercise separately rather than using a higher activity factor.
