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. It's a crucial metric for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\ Multiplier \) — Factor based on activity level (1.2-1.9)

Explanation: The equation multiplies your BMR by an activity factor that represents your daily physical activity level to estimate total daily calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for creating effective weight management plans. 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/day and select your appropriate activity level multiplier. Ensure BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how is it different from TDEE?
A: BMR (Basal Metabolic Rate) is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q2: How do I determine my activity multiplier?
A: Choose based on your daily activity: Sedentary (1.2), Lightly Active (1.375), Moderately Active (1.55), Very Active (1.725), Extremely Active (1.9).

Q3: How accurate is TDEE calculation?
A: It provides a good estimate but individual variations exist. Monitor your weight changes and adjust accordingly.

Q4: Should I recalculate my TDEE regularly?
A: Yes, recalculate when your weight changes significantly or your activity level changes.

Q5: Can TDEE be used for weight loss planning?
A: Absolutely. Creating a calorie deficit of 500-1000 calories below your TDEE typically results in 1-2 pounds of weight loss per week.
