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 activity level. It's crucial 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)
• \( activity\_factor \) — 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 helps determine appropriate calorie intake for weight loss, maintenance, or gain. It's fundamental for creating effective diet and exercise plans.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level. For accurate results, use a recent BMR measurement or calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg) or your activity level changes.

Q3: Are these activity factors accurate for everyone?
A: They're estimates. Individual variations exist based on metabolism, body composition, and exercise intensity.

Q4: Can I use this for weight loss?
A: Yes, consuming 500kcal less than your TDEE daily typically results in about 0.5kg weight loss per week.

Q5: What's more accurate - calculated BMR or measured?
A: Measured BMR (via indirect calorimetry) is more precise but calculated estimates work well for most people.
