1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories your body burns naturally in a day, including basal metabolic rate (BMR) and physical activity. It's the amount of energy 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 complete rest)
• \( Activity Factor \) — Multiplier based on daily activity level

Activity Factors:

• 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. It helps create personalized nutrition and fitness plans.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level based on your daily exercise routine and lifestyle. Accurate BMR calculation is crucial for precise TDEE results.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculator?
A: It provides a good estimate based on standard activity multipliers, but individual variations may occur.

Q3: Should I use TDEE for weight loss?
A: Yes, subtract 500 kcal from your TDEE for approximately 1 pound (0.45 kg) of weight loss per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 10-15 pounds of weight change or if your activity level significantly changes.

Q5: Can TDEE change throughout the day?
A: Yes, TDEE varies based on daily activities, but the calculator provides a daily average estimate.
