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 calories burned through physical activity. It's essential for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for men:

Then calculates TDEE:

Where Activity Factor is:

• 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 you determine how many calories you need to maintain, lose, or gain weight. It's crucial for creating effective diet and exercise plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is the calories your body needs at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this calculator?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas, but individual variations may occur.

Q3: Should I eat at my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should help maintain your current weight.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every few months.

Q5: Can this calculator be used for weight loss?
A: Yes, creating a calorie deficit below your TDEE (typically 500 calories less) can lead to weight loss of about 0.5kg per week.
