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 and digestion.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( \text{activity factor} \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation calculates your total daily calorie needs by multiplying your BMR 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 - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more, and to maintain weight you should match your TDEE.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level from the dropdown menu. Make sure to use an accurate BMR value for best results.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is the calories your body burns at complete rest, while TDEE includes all calories burned throughout the day including physical activity and digestion.

Q2: How accurate is the TDEE calculation?
A: It provides a good estimate, but individual variations in metabolism and activity patterns can affect accuracy. It's best used as a starting point.

Q3: Should I use my actual BMR or estimated BMR?
A: For most accurate results, use a measured BMR if available. Otherwise, use a reliable BMR calculator that considers your age, gender, weight, and height.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, your activity level changes, or every few months to account for metabolic adaptations.

Q5: Can TDEE change over time?
A: Yes, TDEE can change with weight loss/gain, aging, changes in muscle mass, and alterations in activity levels or metabolic health.
