1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, accounting for your basal metabolic rate (BMR) and physical 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)
• \( \text{Activity Factor} \) — Multiplier based on physical activity level

Explanation: The equation accounts for your body's baseline energy needs 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 provides a scientific basis for nutrition planning.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For accurate results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

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

Q2: Should I use TDEE for weight loss?
A: Yes, consuming 300-500 calories below TDEE typically leads to safe weight loss (0.5-1 lb/week).

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

Q5: Can I use this for muscle gain?
A: Yes, consuming 200-500 calories above TDEE supports muscle growth when combined with strength training.
