1. What is TDEE?

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

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( activity\_factor \) — Multiplier based on activity level

Activity Factors:

• 1.2 — Sedentary (little or no exercise)
• 1.375 — Lightly Active (light exercise 1-3 days/week)
• 1.55 — Moderately Active (moderate exercise 3-5 days/week)
• 1.725 — Very Active (hard exercise 6-7 days/week)
• 1.9 — Extremely Active (very hard exercise & physical job)

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: Enter your BMR (use a BMR calculator if unknown) and select your activity level based on your typical weekly exercise routine.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: It provides a good estimate but individual variations exist. Track your results and adjust as needed.

Q2: Should I use TDEE for weight loss?
A: Yes, creating a calorie deficit of 300-500 kcal below your TDEE is a common weight loss strategy.

Q3: How often should I recalculate TDEE?
A: Recalculate whenever your weight changes significantly or your activity level changes.

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: Can TDEE change throughout the week?
A: Yes, your TDEE will be higher on active days than sedentary days. This calculation gives an average.
