1. What is Total Daily Energy Expenditure?

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 a crucial metric for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

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

Activity Factors:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise 1-3 days/week): 1.375
• Moderately active (moderate exercise 3-5 days/week): 1.55
• Very active (hard exercise 6-7 days/week): 1.725
• Extra active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for effective weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps in creating personalized diet plans and achieving fitness goals.

4. Using the Calculator

Tips: Enter your BMR in calories/day and select your appropriate activity level. Ensure BMR is calculated accurately using a reliable method or calculator for precise TDEE estimation.

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 often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 4-6 weeks during weight loss/gain programs.

Q3: Can TDEE vary day to day?
A: Yes, TDEE can vary based on daily activity levels, exercise intensity, and other factors like stress and sleep.

Q4: Is this calculation accurate for everyone?
A: While generally accurate, individual variations in metabolism, body composition, and other factors can affect actual energy expenditure.

Q5: How can I use TDEE for weight loss?
A: Create a calorie deficit of 500-1000 calories per day below your TDEE for safe and sustainable weight loss of 1-2 pounds per week.
