1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and multiplies by activity level:

Where BMR is calculated as:

• Male: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) + 5 \)
• Female: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) - 161 \)

Activity multipliers:

• Sedentary (little or no exercise): 1.2
• Light (exercise 1-3 days/week): 1.375
• Moderate (exercise 3-5 days/week): 1.55
• Active (exercise 6-7 days/week): 1.725
• Very Active (hard exercise daily): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps in weight management - consuming fewer calories than TDEE leads to weight loss, while consuming more leads to weight gain. It's essential for creating effective diet and nutrition plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select gender and activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why use Mifflin-St Jeor equation?
A: It's considered one of the most accurate BMR equations for the general population.

Q2: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (±5 kg).

Q3: What if my activity level changes?
A: Update your activity multiplier to reflect your current exercise routine.

Q4: Are there limitations to this calculation?
A: Individual variations in metabolism, body composition, and other factors can affect accuracy.

Q5: Should I use TDEE for weight loss?
A: Yes, subtract 500 calories from your TDEE for a safe weight loss of about 0.5 kg per week.
