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. It's essential for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\ Factor \) — Multiplier based on activity level (1.2 to 1.9)
• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years

Explanation: The formula calculates your basal metabolic rate first, then multiplies it by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized diet plans and achieve fitness goals.

4. Using the Calculator

Tips: Enter accurate measurements of weight (kg), height (cm), and age. Select your gender and appropriate activity level based on your weekly exercise routine. All values must be valid and within reasonable ranges.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculation?
A: It provides a good estimate for most people, but individual variations in metabolism may affect accuracy.

Q3: Should I use this for weight loss?
A: Yes, subtract 500 calories from your TDEE for a safe weight loss of about 0.5kg per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes (±5kg).

Q5: Are there limitations to this calculation?
A: It may be less accurate for athletes, pregnant women, or individuals with certain medical conditions affecting metabolism.
