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

Explanation: The equation accounts for your baseline metabolism plus additional calories burned through physical activity.

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 plans.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown) and select your activity level. For best results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculator?
A: It uses standard activity multipliers, but individual variations in metabolism and activity can affect accuracy by ±10-15%.

Q2: Should I eat my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight. Adjust ±500 kcal/day for weight loss/gain.

Q3: How often should I recalculate my TDEE?
A: Recalculate after significant weight changes (±10 lbs) or activity level changes.

Q4: Why is my calculated TDEE different from fitness trackers?
A: Fitness trackers estimate calorie burn differently and may include additional factors like heart rate.

Q5: Can TDEE change throughout the week?
A: Yes, TDEE varies daily based on activity. This calculator provides an average estimate.
