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 you want 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)
• \( Activity\_factor \) — Multiplier based on activity level (1.2 to 1.9)

Explanation: The equation accounts for your basic metabolic needs plus the additional calories burned through physical activity.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you create an appropriate calorie plan for your fitness goals. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. The calculator will estimate your total daily calorie needs.

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 calorie needs.

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

Q3: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

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 weight loss?
A: Yes, consuming 300-500 calories below your TDEE typically leads to safe, sustainable weight loss.
