1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including 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 — Extra 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: How is TDEE different from BMR?
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 (5+ lbs) or your activity level changes.

Q3: Can I use this for weight loss?
A: Yes, consuming 500 kcal less than your TDEE daily typically results in ~1 lb/week weight loss.

Q4: Why are there different activity factors?
A: Different activity levels burn different amounts of calories. The factors account for these variations.

Q5: How accurate is this calculation?
A: It provides a good estimate, but individual variations exist. Consider it a starting point and adjust based on results.
