1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. It estimates the calories needed to maintain your current weight.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

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

Activity Levels:

• Sedentary (1.2) — Little to no exercise
• Lightly Active (1.375) — Light exercise 1-3 days/week
• Moderately Active (1.55) — Moderate exercise 3-5 days/week
• Very Active (1.725) — Hard exercise 6-7 days/week
• Extremely Active (1.9) — Very hard exercise, physical job

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more calories than your TDEE.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level based on your weekly exercise routine and lifestyle.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict equations, which consider age, gender, height, and weight.

Q2: Is TDEE the same for everyone?
A: No, TDEE varies based on individual factors like age, gender, weight, height, muscle mass, and activity level.

Q3: How accurate is TDEE calculation?
A: It provides a good estimate, but individual variations exist. Monitor your weight changes and adjust accordingly.

Q4: Should I use TDEE for weight loss?
A: Yes, subtract 300-500 calories from your TDEE for gradual weight loss of 0.5-1 kg per week.

Q5: How often should I recalculate TDEE?
A: Recalculate every 4-6 weeks or when your weight changes significantly or your activity level changes.
