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 and digestion.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

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

Activity Level Multipliers:

• Sedentary: 1.2 (little or 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)
• Extra 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 daily physical activity.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this TDEE calculation?
A: This provides a good estimate, but individual variations in metabolism, body composition, and activity patterns can affect actual energy expenditure.

Q3: Should I use TDEE for weight loss?
A: Yes, consuming 300-500 calories less than your TDEE typically results in safe weight loss of 0.5-1 kg per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or when your weight, activity level, or body composition changes significantly.

Q5: Can TDEE change throughout the week?
A: Yes, TDEE varies daily based on activity levels. This calculation provides an average daily estimate.
