1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is 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, whether your goal is to lose, maintain, or gain weight.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\_multiplier \) — Factor based on your activity level

Explanation: The equation accounts for your base metabolic needs multiplied by your activity level to estimate total daily calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you determine how many calories to consume for your goals. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculator?
A: It provides a good estimate, but individual variations in metabolism and activity can affect actual TDEE.

Q2: Should I adjust my TDEE over time?
A: Yes, as your weight, body composition, or activity levels change, you should recalculate your TDEE.

Q3: What's the best way to determine my BMR?
A: Use a validated BMR calculator that considers your age, gender, weight, and height, or get it measured professionally.

Q4: How often should I recalculate my TDEE?
A: Every 4-6 weeks, or whenever your weight changes significantly or your activity level changes.

Q5: Can I use TDEE for muscle gain?
A: Yes, consuming 250-500 calories above your TDEE can support muscle growth when combined with resistance training.
