1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity \) — Activity multiplier (unitless)

Explanation: The equation multiplies your basal metabolic rate by an activity factor that represents your daily physical activity level.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management. It helps determine how many calories you need to maintain, lose, or gain weight based on your goals.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level from the dropdown menu. The calculator will provide your estimated total daily energy expenditure.

5. Frequently Asked Questions (FAQ)

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

Q2: What if my activity level is between two options?
A: Choose the option that best matches your average weekly activity, or calculate a weighted average if your activity varies significantly.

Q3: How accurate is this TDEE calculation?
A: It provides a good estimate for most people, but individual variations in metabolism and activity patterns can affect accuracy.

Q4: Should I adjust my TDEE over time?
A: Yes, as your weight, body composition, or activity level changes, you should recalculate your TDEE for accurate calorie targets.

Q5: Can I use TDEE for weight loss?
A: Yes, creating a calorie deficit of 500-1000 kcal/day below your TDEE typically results in a safe weight loss of 1-2 pounds per week.
